Roundabouts Are Safer. So Why Does The U.S. Have So Few Of Them?

Roundabouts - the circular intersections seen all over Europe and elsewhere in the world - are said to be far safer than traffic lights. Research shows they reduce crashes, clear up congestion and save cities quite a bit of money. They have a heritage in the U.S., but America has a fraction of the roundabouts that far smaller countries like France, Spain and the United Kingdom have. But there are some states that are adopting them, and one small town in particular: Carmel, Indiana. The people of Carmel love their roundabouts and the mayor credits them with helping revitalize his city. So are they all they’re cracked up to be? And if so, why hasn’t the U.S. adopted them?

Roundabouts Are Safer. So Why Does The U.S. Have So Few Of Them?

Roundabout eliminate 14 points of conflict in what you would see in an intersection, doesnt eliminate other problems like what happens when people over take them and it gets congested or semi-trucks entering two lanes blah blah blah

Civil engineering students need a mandatory course in urban design. It's sad that you can learn transportation without learning the history of urban form. As one of 12 civil engineers who appreciates urban design, I had to read books on my own time.

[@Pesmog]

I worked for a UK company that had a large office in Texas. When the office was refurbed they decided to add a low speed 20mph roundabout that all vehicles would have to negotiate as they entered the site to filter vehicles to either the visitor car park, visitor drop off/reception, staff parking or goods inwards. To say there was an uproar from local staff would be an understatement. However, management stuck to their guns and it was duly installed for when the office reopened, and within a week not a single complaint was heard again apart from visiting delivery drivers who were using it for the first time. 😉 A year later a request for a roundabout to be added to the other office in Chicago came from the staff representative committee as they had heard how good it was !

@@Yautah That dread is understandable, and comes from the same culture shock, that a student that just graduated from grade school, probably experiences going to collage, or out in the real world for the first time. Roundabouts have been more prevalent in the UK longer then the US. So they are a new thing to get the just of to a lot of us American drivers. Like for an example, if you get me to tackle one of the big multi lane roundabouts in England without learning how it works first, I would be as lost of it like Chevy Chase [Clark Griswold], driving it in circles all day, if you know what movie i am referring to.

Go to the UK. In the vast majority of places where the US would have a stop sign, it is a 'give way' (what the Brits use instead of yield) sign. It is far superior for everyone except maybe the braindead Americans.

[@SmallSpoonBrigade]

Yes, it means that basically all roads are all way stops as you need to figure out who gets to go first. Also, horses aren't likely to be too keen on t-boning the other vehicle.

[@cgpcgp3239]

I live in a country like that for a few years. We joked the right of way was trucks, cars, motor bikes, pedestrians. Crossed at your own risk. When lights were install in town where I lived (about 100,000) not everyone got the memo. Some drivers thought red light meant go. Some thought green meant go. Everyone eventually figured it out. Stop lights were a great idea.

[@JaidenJimenez86]

I often see comments from truck drivers criticizing roundabouts - I'm a truck driver in the UK and they're great for us. Every trucker knows how much of a pain stopping and starting is, particularly at night when there's no other traffic. Also, they make every turn a wide swing, you don't have to jacknife the trailer on a tight crossroads - and they give you the chance to turn around rather than doing a series of turns around the block. They only become an issue when the town puts a load of trees in the centre, so you can't easily see if something is approaching from the other side, trucks take off very slowly, so often you can be 6 feet into a roundabout and a car comes along, especially if they're driving quickly.

[@redxslayer6922]

United States Semi trucks are bigger compared to UK trucks, therefore making U.S. trucks harder to maneuver. In the United States, a Semi truck needs almost half of the intersection space to make right-hand turn. Having a roundabout in the middle would prohibit the Semi from making that turn. They would either have to remove the sidewalks to create more space or make the island in the middle extremely small. You have to take into consideration that there are a lot of Semi trucks that drive through small towns with narrow roads, having a roundabout would just not fit.

[@Niowi]

They don’t make them big enough for the trucks in the USA just like poster stated. They’re entirely a waste of money here in the us as they serve no purpose other than to lower costs for heap ass cities and increase accidents because people are too rude to allow others to join the flow, and hence make them less than ideal here

[@dbclass4075]

​@@redxslayer6922That is what the textured curb in the island is for: for truck use, while discouraging light vehicles to drive over it. Another technique is to make the entrances and exits more tangent to the circle. This will reduce the turning angle required for long vehicles. And if space is indeed an issue (roundabouts works opitmally with large circumference), make use of yield and priority rules instead.

[@dbclass4075]

​​@@NiowiBut those accidents are less severe, partly due to reduced angle, but mostly due to reduced speed. Cheaper fender bumpers instead of expensive body repair or hospital bills. Also, less red-light and stop sign tickets.

[@Niowi]

@@dbclass4075 ok, /I get all that, but the main reason they’re useless, is because four wheelers are to aggressively driving in them causing the issues. I have seen some newer ones that actually have a lane for trucks going directly to the first 90 degree turn that gives longer vehicles with trailer a way in but that only mitigates the right turn of each lane, but does help. The problem with going straight or to the left turn, if the circle has a painted line bordering it, then every time we drove into that circle and trailer tires crossed it, we’d be subject to a fine/ticket, because as a big truck with company name on it is easy prey for police and for scammers trying to use insurance scans. I’m not totally saying it dumb, but as they’re made now, they are more trouble than the old plain Jane 4 way intersections

[@nando7422]

I live in Idaho and the city I'm in started to build roundabouts back in 2018 and people were angry the city was doing away with 4 way stops. The last 4 miles of my commute from work to home use to take about 30-40 minutes depending on the day of the week but has been reduced to about 6 minutes thanks to the roundabouts. I feel people resisted them because the weren't sure how to use them but now everyone praises them.

[@kiddwong4186]

Holy crap 30 minutes to 6 minutes? That's absurd

[@okamijubei]

Sounds like a great way to start... But we still have a long way to adapt. There's a town near by from where I live have a couple of roundabouts but they feel a bit too large and should have better traffic control

[@davidmartensson273]

I live in Sweden and I actually only know of one single 4 way stop intersection and its small low traffic intersection and the only reason they even added the stop signs is due to bad visibility and there is not room for a roundabout. And I do live in the suburbs of the capital city of Stockholm. 4 way stops just does not seem to exist at all. We do of cause have traffic lights but roundabouts is so common that on the way from home to the closest big shopping area I pass 8 roundabouts and 3 traffic lights, and then another 3-5 roundabouts depending on what part of the shopping area I am going to, there are no traffic lights except for pedestrian crossings within the shopping area.

[@travislogan1482]

Did they bother to teach drivers about them or just build them and expect drivers to figure them out? That's the problem I've seen. Cites just put them in and don't do a damn thing to educate the masses how to use them.

[@arodvaz1955]

If they have the signs, they're pretty explanatory. I used to take one, though, in which people just ignored the stop signs and it became sort of a hot wheels circuit.

[@joe42m13]

My city put in 3 roundabouts a few years back and people LOST. THEIR. MINDS. You'd think they were trying to switch to driving in the left lane with all the panic that ensued. Fast-forward to the present and people are used to it, and they definitely help with the flow of traffic. I even bike through them almost daily, though if traffic is a little worrisome I can always use the sidewalk.

We had really big ones 40 years ago, maybe 200 feet across the center. The law was going 1/2 or 3/4 round meant using the inside lane (which had the right of way) and then turning right over the outside lane. That was scary on a motorcycle, we all stuck to the right lane.

I used to be anti-roundabout, but over time more of them have popped up where I live. Once you get used to driving through them and learn the rules of the road, they are actually quite good, as traffic isn't hindered by waiting at long traffic lights.

[@elliottyeomans654]

The problem here in Australia is that people are not educated to know how to use a roundabout so instead of telling them how to use them they are going back to lighted intersections.

[@barneyklingenberg4078]

They are good if they’re used on the right places. Here in the Netherlands we have roads with 9 roundabouts in 6 km from which 3-4 have side roads leading to nowhere. Or maybe a very tiny industrial lot. That becomes an utter menace for trucks. However the big one near the highway is doing an fantastic job. As are the ones connecting major urban area’s to the main road. Basically traffic engineers need to come with a under limit of traffic for roundabouts. Not replace every crossing with one.

[@dave20thmay]

@@elliottyeomans654 The same is happening here in the UK. With more roundabouts being put on decent roads, with a huge change of direction, so estates can be build. Now traffic lights being installed on roundabouts, when you are waiting and there is no other vehicles around and even removing big roundabouts to make multilane intersection. We have got this because of the attitude of drivers that think they own it and race onto it, instead of using it as a filter by balancing the flow. Best Dave

[@advancetotabletop5328]

[@SwarmerBees]

I guess the grass is always greener. Here in Christchurch 20 years ago they were the default for intersections but now they are being removed and becoming rare because they are a menace to public safety. In particular, large numbers of collisions occur in the two lane ones when the person in the inside lane is exiting and the person in the outside lane is not paying attention and all involved are focusing on other vehicles rather than pedestrians or bicyclists around such busy roundabouts. Bar none the highest death tolls are at such multilane roundabouts and they were rightly removed. The thing is, when people are used to roundabouts, agressive drivers such as tradies late for a job create exceptionally dangerous situations requiring that all drivers have excellent situational awareness and reactions. With distracted or with drivers whose reaction time is sluggish, it gets messy. 20 years ago, people drove far less aggressively so they can work so long as people do not engage in risky driving practices. Perhaps the US tests are skewed due to the unfamiliarity of the subjects with roundabouts thereby instilling caution. Any planners taking this youtube presentation seriously needs to ask why countries with long experience with roundabouts are eliminating them.

[@sonyphotoguy6601]

Or maybe Americans are just too dumb. This is what I think because roundabouts are a smart solution. The Video explains it very well. @@SwarmerBees

[@VidsPhone]

After all Indianapolis just down the road is "The Circle City". Indiana is famous for the Indy 500. consisting of going around a circle 200 times. Roundabouts are good for the people who live there and know the area and exactly where they are going. For people coming into the city for one afternoon for an appointment they can be a nightmare to figure out where you are going. I refuse to believe that one stoplight costs 400,000 dollars. That is adjusted for government cost over runs like the 300 dollar hammer. Isn't he the same mayor who wanted to import an antique carousel for downtown Carmel? He seems to be totally fixated on going around in circles. His life is a non stopped game of "Pin the tail on the donkey". I live near Indianapolis and go to Carmel often. The roundabouts explain why Carmel people are so dizzy all the time.

[@peter_smyth]

One of the best features of roundabouts is that when there's little traffic, nobody has to stop, unlike a four-way stop or a junction with lights (unless the lights are responsive to traffic).

[@Stratelier]

Even with "responsive" lights, when you approach from the non-prevailing direction you generally have to stop anyway before the light responds to you so you can cross.

[@flagmichael]

Our problem is that one has been placed on an extremely busy intersection, so that traffic flowing from one direction to the opposite side monopolizes the roundabout. If something interrupts the flow that way, the torrent of pent up traffic the other way locks it up again.

[@rian132ful]

Traffic light guarantee everybody passes the junction slowly, while roundabouts cant guarantee everybody can pass the junction quickly. Still, roundabouts havr significantly faster/more efficient traffic

[@fishhuntadventure]

What are you talking about?! I’m sick of waiting behind other drivers at traffic circles who dutifully stop for the triangular sign, and look repeatedly left and right to confirm if traffic will allow them to enter… 5:09 …without any other car or traffic in sight. Eventually, a car will come. They inch forward and we wait yet again for the unseen car to magically appear. Traffic circles don’t solve problems for mentally impaired drivers, they just keep the stupid people that shouldn’t have a license anyway from being filtered out by the Darwin Award program.

[@evilbob840]

@@fishhuntadventure I think this is mostly from people that aren't familiar with them. There are a few roundabouts near me and I almost never see the "nervous stoppers" you are talking about. One interesting thing: there is a road really close to my house with a roundabout and a 4-way stop about 100 yards apart. Both get about the same amount of traffic, but the roundabout during high traffic times is still quicker to go through than the stop during low traffic times.

German towns generally IMHO also are too stupid to understand that it makes no sense to put roundabouts in any place. This leads to problems for lorry drivers when they set up these nice plants in the middle of the roundabout. What I don´t get (please feel free to educate me on this) is, why they put up the 'yield' sign on the entrances to the roundabouts. Is it because the traffic within the roundabout has by default not the right of way ? (which would be a flaw in the general rules, it makes no sense otherwise) - or is it because most people are incapable of understanding that the traffic within the roundabout has the way of right - even though they (by definition) come from the left side!?

Last year I vacationed in The UK and had a rental car. The roads were narrow, cramped, and not many multi lane roads. Driving through Salisbury, there was a lot of traffic, and I feared it would take forever. To my surprise, the traffic moved a constant 30 mph and flowed smoothly through the roundabouts. It took less time to get through a similar sized city than in the US, and the constant movement alleviated feelings of impatience. It was a completely different experience. That being said, the lack of available parking near destinations was much worse than in the US, and was annoying. The few traffic lights that existed were also different. In the US, the traffic turns from green to yellow to red. It also does that in the UK, but it also has a yellow phase between red and green, so you know when to anticipate a change. This resulted in much fewer red light runners, and it also made people take off on green in a much quicker and more orderly fashion. It was fascinating.

Having lived in most of the countries mentioned here (Spain, UK and the Netherlands) I have to say that the Netherlands has by far the best traffic solutions. France and Spain have arguably too many roundabouts and plonck them down everywhere whereas in the Netherlands, when creating new infrastructure, the situation is always carefully analyzed by the traffic planners to see what intersection solution is most suitable be it traffic lights (almost ALL Dutch traffic lights are "smart" and work with multiple sensors built into the roads which will detect traffic and decide based on that which lights turn green), single lane/double lane or turbo roundabouts. Turning the traditional US traffic light intersections into roundabouts will not always work because it's not planned ahead of time and therefore doesn't fully cooperate with the surrounding infrastructure. If you want to learn more about European (mainly Dutch) city planning I highly recommend the KZbin channel "not just bikes" which is ran by a Canadian bloke.

I live in Upstate NY. Due to NY policy when an intersection is redone it is usually replaced with a roundabout. In general this works well and traffic seems to flow well. The one exception that I found is an area where the road was redone for a section of about a mile and there were 5 roundabouts installed in a row. If you are traveling in the right direction you will hit all 5 of them. These are spaces very close together so as you exit one roundabout you immediately enter the next. By the time you are through all 5 you are dizzy from all the turns.

4 way stops are the result of differing traffic laws. In Europe, you give way to cars from the right, unless otherwise stated, whereas in America you give way to cars on the biggest road. In suburban situation there usually is no "bigger" road, so they place 4-way stop signs. In Europe that isn't necessary because traffic law already accounts for those situations.

One of the most infuriating and frustrating aspects of life in California was waiting at endless inefficient stop lights, or worse, 4-way or 2-way stop intersections. 2-way stop intersections were especially dangerous since the drivers with priority had no sign and had to rely on the drivers with the stop sign to read and observe that it was a 2-way and not a 4-way stop. Since the data are so clear regarding roundabouts, it was doubly frustrating when new roads were built only to include the inevitable stop signs and traffic lights.

I encountered in Poland a lot of bad drivers that would purposely sit in the outside lane of the roundabout and never exit, blocking traffic from leaving from the middle/second lane which was legal to do. When entering a multiple lane roundabout, if you enter on the outside lane, you are required to be exiting on the NEXT exit. You cannot sit there and continue to go 2+ exits more or else you will be hit by other cars or force them to have to stop in their lane to wait for you to pass in front of them. It becomes super dangerous when people don't follow the law.

Roundabouts are slowly getting more and more common in the USA. Here in WA state, it seems like I see a new one about once a week. I used to hate roundabouts--mainly because other drivers didn't know how to deal with them. But over time I have grown to like roundabouts. My three main reasons are: 1) No stopping and sitting at a red light when no one else is there. This just drives me nuts when a light refuses to turn green and there is NO ONE else at the intersection. Roundabout? Just cruise on through the intersection. 2) I feel safer. Ever seen someone BLOW through a red light doing about 60mph? Yep, that's tougher to do with a roundabout. Sure, there are still going to be accidents with roundabouts, but they are far more likely to be low speed fender bender accidents than high speed collisions where people get killed. 3) Power outages. Every time we have a power outage around here, the typical traffic light intersection gets extremely dangerous. People do NOT treat these intersections like 4 way stops as they are supposed to. You get people blowing through the intersection when the power is out. It's a great way to get killed. Roundabouts don't care if the power is out. They still work as they are supposed to. I understand that many people don't like roundabouts just because it is something new and different. People aren't used to them. But, over time, people will get more and more used to them and accept them--just like everything else.

FYI: Causeway Blvd. in Metairie LA was constructed around 1956 (as a continuation of the Causeway bridge across Lake Pontchartrain). Where it intersects Airline Hwy they built a direct straight overpass with a lower level Roundabout (for entry or exit onto Airline). They also built a depressed underpass used by Airline Hwy. (Causeway went up and over, while Airline went down and under). The Roundabout had two up-ramps from Airline as well as two down-ramps onto Airline. All four of these fed into the Roundabout. From the Roundabout you could also enter or leave Causeway OR use it as an alternate route bypassing the straight overpass. Also the Roundabout was often used as an alternate route from Airline to Airline either direction when the Airline underpass flooded.

I came to Canada from the UK back in 1976 and I STILL approach this Whitby-Oshawa roundabout with some trepidation. Even though it's been in place for nearly 10 years. It worries me because, still, VERY FEW drivers using it have any understanding of how it's supposed to work. So, instead of the traffic flowing smoothly, most drivers (even myself) stop at the 'Yield' sign and CAREFULLY look EVERY WAY before tentatively moving slowly into the roundabout itself. Because, all too often, someone drives into the roundabout at full throttle, without looking, and basically screeches round it on two wheels before speeding off their chosen exit. So DON'T just build ONE roundabout in such a population and expect drivers to understand it and trust it and use it safely. Because too few drivers have any real opportunity to properly get used to the concept of roundabouts.

The roads are marked with arrows indicating the direction of travel and the destination of each lane is shown on both entering signs and overhead gantries where applicable. Traffic control lights may be required if the junctions are complex and traffic heavy. Sat nav is usually effective in directing which lane you should be in and follow at each step.

The best thing to do is understand which exit you have to use ( 2 or 5th Exit) What you do is position yourself on the left lane if you plan to get off the 2nd exit and use the road markings to follow the circle and stay in your lane make sure you signal to the right until you pass the 1st exit. You then have to signal left to get off your 2nd exit. if you plan to take the 5th exit you position yourself on the right lane and signal right then follow the road markings that will take you around the roundabout.

[@celeritasc9207]

@@shirhan21 I figured that there was such a strategy, and understood that for a later exit I needed to be in a lane further in. But, when the roundabout is completely full and no one has enough courteousness to allow someone to make a lane change, as a first experience, it was beyond my ability navigate. I am just glad that we don’t have such large ones over here.

I don't mind a properly designed roundabout, but they do take up a lot of land so it is hard to retrofit them where an intersection has buildings nearby. Tiny roundabouts that let drivers go almost straight through without reducing speed are very dangerous and force those in the roundabout to yield to those entering to reduce their risk.

[@limerickman8512]

Traffic lights are the worst thing, especially when they put them on roundabouts. All I want if anyone turning right, that a small slip road is used for waiting to turn off the road. In my old local town they redeveloped the main road through the town. They put in the slip road (locals demanded it) to enter the town and they put a traffic light on it. Well one weekend the traffic lights malfunctioned and was turned off. That weekend traffic moved smoothly through the town. The following weekend a summer August bank holiday traffic chaos with very long queues on both sides of the town, causing back up into the town center (not on main road). Well the local sergeant was fed up (as it was also dangerous) went to the traffic light and turned it off. Long waits of traffic disappeared within the hour and did not build up. Usually they direct traffic when they turn off the traffic light, but he was distracted with dealing with a local thug and after 15 minutes, noticed that traffic was moving smoothly. Traffic lights always build up traffic and creates cortina type effects, which is a dangerous situation for drivers on main roads, which frustrate drivers. Well that weekend after the local traffic lights was turned off, there was far less accidents on the main road that weekend. So when ever there is heavy traffic they turn off the traffic light, and do not have to post an officer on road duties. The council eventually removed the traffic light, as the sergeant threaten to permanently turn it off for public safety, or there will be delays to deal with council safety situations because they cannot get across town due to the traffic light chaos. He suggested a different area for it.

Spain has a type of roundabout that I have not seen anywhere else. It is a complex set-up where the main road splits the roundabout and the various entry and exit points are controlled by yield signs, stop signs and traffic lights.

[@Nils.Minimalist]

As a German, I am really used to roundabouts but when I was in Ireland once, I was very confused. They had additional traffic lights inside the roundabout in Ireland. And once when I stopped there at a red light in a roundabout, a car behind me honked for me to go. I was more confused than ever before in my life because I learned that I had to stop my car at red lights.

[@claudiupaun4282]

We have a few of those in Romania as well, the design is of a roundabout but is generally just a bigger circle intersection where if you want to turn left using that "roundabout", you'd have a red light (functions the same way as a squared/normal intersection where you'd turn left and will have to wait for the incoming traffic before turning left, but also, if the lights are not working, it functions as a normal roundabout). In your case, if you were going straight, then you just ignore the red light as it is not addressed to you Hopefully my explanation isn't as confusing as I think it is, but hey, can't draw on youtube comments :)

[@geoffreycodnett6570]

UK has a lot of roundabouts with full or part time traffic signals. The lights work exactly as standard signals. They're used on very busy routes particularly on motorway access roads. Roundabouts were named after the funfair roundabouts seen in funfairs from the 1800s onwards.

[@donkeysunited]

They're called traffic light controlled roundabouts. I imagine they are needed where traffic coming from one direction would dominate the roundabout preventing traffic from another direction ever getting on. But don't ignore the lights in Ireland. The driver behind you likely didn't see the red light. Also be careful entering the roundabout on a green light as the guy already on the roundabout with a red light might think he has right of way. It's rare but can happen.

I lived in Mexico for 8 years and used "glorietas" a lot. They work great most of the time until one major road saturates the circle, preventing vehicles from entering from the crossroad. When there is no gap in the traffic, traffic cops would step in during rush hour to keep things moving in all directions, but with backups. Eventually, it got so bad that they converted some of the worst glorietas to signaled intersections.

[@jacke6579]

In the UK, many roundabout also have traffic lights that stop people already on the roundabout to let people on. Some less busy roundabouts actually turn these traffic lights off at quieter times - that seems like the perfect solution, you effectively have a roundabout combined with a traffic light intersection.

[@nezahualcoyotl1135]

I have been living in Mexico for the best part of 20 years now, and while you get congestion at roundabouts, people will usually just push in when there's no gaps, which overall works surprisingly well. Signalled crossings tend to be catastrophic with dense traffic, i.e. workdays from 5AM to 10PM.

I live in Monaco and drive to the UK fairly frequently, I find that I switch from one side of the road, to the other as soon as I drive off the ferry without even thinking about it. The same with navigating a roundabout. Interestingly, there are small differences in rules at roundabouts in different countries, but the UK is the easiest as, with very few exceptions, the rules are the same. It's different in France for example, as there can be slight differences in roundabout rules in different locations. One is warned about this with signs before the roundabout. It's not a big deal though, roundabouts are easy to navigate.

[@TheLoathsomeCowboy]

Roundabouts in heavy traffic areas only work if the incoming traffic streams are fairly even. Once one traffic stream gets to dominate, then the other traffic streams have difficulty entering the roundabout. In my part of the world (UK), when this problem becomes long term, traffic lights often get placed on the roundabout to give the lighter streams a chance to move through. I refer to these as failed roundabouts, as they don’t work as intended.

There is one critical flaw with roundabouts in the US, especially in my state which is they don't put any signs up telling you what exit goes where. Contrast to in Europe and they have signs all over the place, even on both sides of the road before and after each exit. I love roundabouts and far better way in my opinion but if you don't put adequate (or any) signage it's going to be incredibly frustrating.

[@barbarakiewe2870]

Roundabouts are more efficient up until a certain threshold of traffic volume. Once you exceed that threshold, they actually become less efficient than a managed traffic signal. The key to implementing roundabouts in the U.S. is to stay one step ahead in managing traffic volume on any given route (adding lanes, enabling alternate routes, etc.).

[@KafanskaTV]

You can always add traffic lights before the roundabout if the traffic conditions end up demanding it.

[@janekschleicher9661]

More traffic volume handling roads aren't the answer anywhere (if it would be, then Houston or L.A. would be great cities to drive around, wouldn't they?). If you have high traffic volume, you need transport with more capacity: Trains, Subways, Busses, Bikes or at best try to make it pedestrian friendly (as it has the highest capacity). Inducing demand for traffic for low capacity (cars), doesn't scale at all, as at that point where managed traffic signal becomes more efficient, every further car doesn't add congestion lineary, but much more worse. I pretty much was shocked to hear the German professor to make the same mistake, especially as all he would need to do is to look out of the window of his university as it is in the region of Germany where you can exactly see this problem (the have highest density of roads, not many roundabouts, but also highest congestion rates in Germany, while still having a bad public transport system, no bike infrastrusture and not being much pedestrian friendly). tldr; if you have high traffic volume, the best action is to reduce the (inefficient) traffic, not induce more (inefficient) traffic (and by doing it, make all much more higher capacity, more efficient traffic less attractive).

And too many drivers race through them without slowing down. It is really hard to merge into it when some fool is racing through and will obviously hit you at full speed if you enter it.

I like roundabouts, but there are two downsides that weren't mentioned. First, they take up more land than traffic intersections. That's a big deal in downtown areas, where land is very expensive. Second, if semi-tractor trailers need to pass through them, the roundabout needs a big radius, which takes up even more land. One extra plus: if a driver needs to go in the opposite direction, they can do a 180 turn quickly and safely.

[@geoffreycodnett6570]

The UK has "mini" roundabouts to cope with intersections that don't have space for a "real" one. These consist of a white circular patch in white, sometimes raised slightly, on a crossroads or junction. As the rule is to give way to traffic entering from the right it permits a free flow from all entering roads. It makes more sense than having give way signs holding traffic from side roads which may be equally busy but minor routes. No requirement to not drive over the white patch makes it work for long vehicles.

[@tapio_m6861]

The way I look at a roundabout is that it's essentially a one-way main road and if I want enter it, I must yield to anyone already on it. If I want to leave it, I signal and turn away. That's it. I some countries (Sweden for instance), they signal into the center whenever they are in it, so they might think of it differently, but here in Finland we only signal whenever we want to leave the roundabout so as to tell the driver about to enter it that I'm leaving the merry-go-around. Roundabouts work best when the drivers understand and anticipate what's about to happen. For instance, one roundabout near me connects a much busier street with a less busy one. That means that whenever I'm coming from the less busy one, I need to look at what's happening in the roundabout. I'm looking for a gap in the traffic on the main street, so whenever the next car coming from the main street (on my left) has to stop to yield to pedestrians or other traffic, that's my cue to go. Makes for a much more efficient intersection.

[@JohnoEx]

In Australia we have some roundabouts where a tram runs through the middle of it. Can be unnerving for unfamiliar drivers as you not only give way to other cars on the roundabout but also to the tram that passes through the middle.
