Huge thanks to CuriosityStream for supporting Vsauce2.
We play two-player games all day, every day, and our lives are a real-time exercise in game theory. We work out how to make the best move based not only on what we want the outcome to be, but also based on how we think the other player is going to act. Since they’re usually going through the same rough thought process -- sometimes consciously, sometimes subconsciously -- we’re embroiled in a constant series of games with all of us wanting to win.
Winning can be the best result for you or the best outcome given the circumstances, and players are implicitly sorting out their strategies in a recursive process that waffles between self-interest and cooperation. Whether we’re driving down the highway and trying to go as fast as we can without getting pulled over or just trying not to be weird with our crush, we’re playing a game… and it turns out that a little cooperation goes a long way.

[@captainzoll3303]

Officer: "do you know how fast you were going?" Kevin: "Speed is relative, Officer."

[@eadbert1935]

Officer: you were driving 20 km/h over the speed limit Heisenberg: where am i?

[@timothyneiswander3151]

The answer to that questions is always,"I'm sorry, I was concentrating on where I was going and the traffic around me and I had not looked at me speedometer in miles." This statement does 2 things: it keeps you from incriminating yourself and informs the officer that although you may have been speeding you were not being reckless. Often an officer will ask that question if he doesn't have solid evidence of you speeding. If he says he is going to ticket you, request to see the radar receipt. The radar will print a time/date stamped receipt when he clocks you. If he can't produce it then he will either not ticket you or you can go to court and dispute it.

[@UnderTheMillkyWay]

Timothy Neiswander screenshot and saved to my phone. Not that I speed because I don't unless I'm not paying attention to my speed on a long stretch just watching the road but I typically can feel if I'm speeding because my foot will hurt. That may sound kinda odd but I typically drive at 58 miles per hour or 68 miles per hour depending on roads. My foot is so use to applying pressure for those two speeds and if I go over those speeds especially 68 I start to get a cramp. I don't know if it is from muscle memory or what. I usually drive 79 miles to work so it's kind of a haul but my foot is very steady and I can usually tell pretty quickly if I speeding and slow down but I rarely do speed so I think it really is muscle memory for me. Long rant but I've noticed this for years but your screen shot might help me if I do get stopped. Good tip and sounds logical.

Something I'd add about the nash equilibrium in the prisoner's dilemma situation is that if you tally up total scores in each outcome, both keeping quiet ends up as -2. Both talking ends up at -4. One talking and the other keeping quiet ends at -3. I mean group total. The rational actor in this situation will think as an individual and seek the 0, because it's the most positive result for all of this, on an individual scale, but this means both will likely do this, and lead to a collective -4. Team players generate the highest score on a group level, loners generate the lowest and shittiest score on a group level. Realistically speaking, nash equilibrium would always happen and you'd never see one side get 0 and the other -3.

[@joshuawhitman8254]

There’s another variable not accounted for: How fast MUST you go before you CAN be pulled over? Many jurisdictions, often times entire states have laws in place that set hard limits on when someone can be cited for speeding. Many states require the offender to be exceeding the speed limit by a certain amount before they can be cited (for example greater than 10mph over). Further, different speed measuring devices can have these limits set differently (LIDAR, RADAR, Pacing, aerial etc). This is further compounded by the fact that different laws may apply to different agencies that work in the same jurisdiction. For example State patrol may be able to cite you for 56 in a 55 but a PD may not be legally able to cite you on the same road until you are going 70.

[@GrapeDrank001]

The weight of thr car makes the tires rubber depress causing it to have a larger contact patch

[@Baigle1]

a lot of 'engineering' and science channels completely miss the fact that force per area depending on the compound squishes the rubber into the pores of the road and vice versa... engineering explained really fked that up. whole reason we use rubber in the first place besides shock absorption. more to it than just contact patch, the rubber liquifies into different pseudo-states depending on temp and a ton of other stuff.

[@SuperSerNiko97]

CuckTube we use rubber because it has a higher friction coefficient. Doesn’t really matter the surface, it’s all about weight and acceleration. And that’s because more surface area means less weight per inch square (these are the very basics of physics).

[@GrapeDrank001]

@@SuperSerNiko97 more surface area mean more traction thats why you dont over inflate your tires so theyre at the optimal point of havin just the right amount of traction too little and theres too much surface area or a contact patch meaning more friction and the vehicle wont be efficient and wont preform perform optimally because the friction will slow it down too much air and the tires will be too firm and have too little of a contact patch meaning less friction and you will lose traction and slide around

[@SuperSerNiko97]

GrapeDrank001 that’s absolutely wrong, bicycles and motorcycle have much less contact area than cars or trucks but handle the same lateral force, explain why! The friction law of physics only depend on weight and material, the surface area cancels out. Sport cars have wider tires for many other engineering reasons, for example: a wider tire have less deflection so the car is more stable; a wider tire touches the ground more transversally than longitudinally, so the tire touches the ground for less time (and when they do the pressure on the ground is softer) but touches the air for more time, this means a more colder tire; and last but not least a wider tire, due to the less pressure on the ground, last longer. Put all those things together and you’ll find out that you can use a much softer tire without all the trouble you would have on a narrow one. Talking about what you said, you have to inflate it at the right point not because of any crucial change in the traction but because you use all the tread homogeneously without wasting it.

When an alligator chases you, you don't have to outrun the alligator, you just have to outrun the slowest person running from the alligator. Same concept in reverse for speeders. You don't have to drive below the limit, you just have to drive slower than the fastest person in the pack. The cop can only write one ticket at a time.

[@paulrdgers3914]

I was taught during drivers training that it's generally ok to go about 10% over the limit assuming you're already driving with the flow of traffic. If you're alone, do the limit, but if theres a dozen cars or more around you doing 15 over, go with it.

[@ChristopherWanha]

TIL: Recursion is a pattern of incremental change that repeats until it reaches a base-case. In this video, the base case is getting pulled over. The change is usually one directional, so, for example, the non-cop-driver starts at 60, and doesn't get pulled over, the next round the driver goes 61, then 62, etc, etc. Eventually, this pattern stops when the driver is pulled over. That is recursion. Recursion usually doesn't go to infinity because it reaches Game theory is also a repeating pattern of incremental change, but it can go in more than one direction. The base case is when change = 0. An example I heard of was two vendors selling goods at the beach, and the change they make is where to set up shop. If both vendors are equally spaced out on the beach they might get equal shares in the business, but if one decides to move toward the center, it will be more convenient for customers to go there and less to the other making the one who moved get a larger share of the business. The vendor getting less business will likely respond by moving closer to the center until he receives most of the business, then back to the first one who moved, he'll move again until he gets most of the business ... this pattern repeats until both vendors are right next to each other in the middle. This is an explanation used for why so many gas stations are right next to each other. So in the example in the video, game-theory is being applied in a different way where one party incrementally controls their speed, but the other party (the police) incrementally adjusts their threshold for how fast they are willing to let a civilian drive before pulling them over. This pattern repeats forever until a driver gets pulled over. But it results in a sort of mid-point (called the Nash-equilibrium) of how fast one can drive without getting pulled over resulting in an actual speed limit that is somewhat faster than the road-signs. Interesting enough, this game is not played by two parties, but by all drivers and all police within a given area. Thus the equilibrium ends of being determined by how fast most people drive in an area thus if you were driving in an area where EVERYONE except for you goes the speed limit, then you might get pulled over for going 1 mile over. However, if you are in an area where everyone goes 20 mph over the speed limit, then you going 19 miles over the speed limit greatly reduces the odds of you getting pulled over while allowing you to still speed.

I had a cop tell me “9 you’re fine, 10 you’re mine” talking about MPH over the speed limit.

[@thomasharris4562]

I am glad you clarified that he was talking about speed limit

[@Outliver]

I think there is more to it than just applying the prisoner's dilemma. The reason is that, if you're driving 5mph too fast when the speed limit is only 10mph, that's 1.5 times as fast as allowed whereas with a limit of 65 that's only 1.08 times. So the probability of the cops pulling you out depends not on the absolute value of mph you're over the speed limit but the relative amount. Thus, the actual solution needs to be logarithmic.

I've concluded for a few years now that the best course of action is to be nice; even if I suffer because someone isn't nice, there is fulfillment in doing the best you can. When I set immediate emotions aside, it also seems worth taking the course of action that provides the best outcome regardless of their immediate emotions, because speculative recursion defies the generally practical Occam's razor principle. Do best, hope others do best, and remember that if you don't, its impossible for everyone to do best at once.

The coefficient of friction/maximum velocity a car can turn around a corner has nothing to do with how much area of contact there is between the tires and the road, it's all about the kind of surfaces that are in contact/providing the friction. The equation for the force of friction is Friction = Normal Force x Coefficient of Friction, there is no accounting for the area of the contact between the surfaces, because it doesn't matter. Another way to think about this is that the bigger the contact patch is, the lower the pressure is on that patch/the less weight there is per unit area of the patch. With a smaller area providing friction, there is a higher amount of friction per square unit, and vice versa (bigger area provides lower amount of friction per square unit of area)

Hitler: "commits suicide" Vsauce: or did he?

[@thaferg6969]

If your tyre is correct pressure then there's the most contact. That said when it's underinflated there's actually a pocket that forms in the middle due to the sidewall being pushed towards the center and creating an arch thus reducing surface contact area. If it's wet you'll probably have less grip if you're underinflated rather than overinflated. You may have better grip if you're over inflated than regular when it's wet.

[@niklaspfafenrot9111]

It CREATES centripetal force. That was his mistake. What you say is wrong.

[@MexicanSpinach]

No it's not :P "the peg resists a centripetal force, which wants to sling it off" centrifugal force is what wants to sling it off, he named the wrong force.

[@niklaspfafenrot9111]

@@MexicanSpinach no the mistake was the verb, not the force itself. Centrifugal force doesnt really exist, its just the inertia force. Look it up if you dont believe me.

[@MexicanSpinach]

@@niklaspfafenrot9111 I've been studying physics for a few years, I realize that it doesn't exist, it's the object's attempt at moving tangent to it's circular path at any given point, and a centripetal force is necessary to keep it on its circular path. But that isn't my point, which it seems you missed. He said "the peg resists a centripetal force, which is trying to sling it off." With that last part, he clearly specified that he was talking about centrifugal force.

I generally do 9 miles over the speed limit. Havent been pull over yet. One tip is if a police car is following you but no siren, simply slow down and let it pass. I believe there is a rule where it wont give you ticket yet when it sees you overspeed. It will observe you and if you make one more mistake then its ticket time.

Pennsylvania resident: If you're not going at least 10 mph over the speed limit, you're gonna get tailgated for going too slow. On my daily commute, I tend to put on cruise control on about 13 mph over, though I regularly get passed even on days where I'm running late and going a full 20 mph, which is technically enough to lose your licence for. I mean, these guys are cruising at least 25, maybe even 30 or 35 mph over the speed limit. Regular everyday occurrence and nobody looks twice, even the cops.

[@FoolOverride]

In australia, the threshold is 3km/h. When you get a speeding fine, 3km/h is taken away from the speed. So if you drive at 63km/h and a cop scans you, 3km will be taken off your total speed, bringing it down to 60, the speed limit. At 64km/h, the number would be dropped to 61, which can be fined. Thats how it works in Australia however. And yes, 61 will land you a $150 fine for traveling more than the speed limit but less then 5km/h over the limit.

the problem with the prisoner's dilemma is that the two prisoner's can't communicate, meaning that they can't agree not to rat. if they could communicate they would agree not to rat because they both have brains. unfortunately, they can't communicate, so neither knows if the other is nice or not nice, and what you do won't affect the other person's move.

[@NetAndyCz]

I believe that speed limit is set in place as another form of taxation. It has nothing to do with actual safety, because safe speed is always relative and depends on the car, the driver, the traffic, the road, and the weather.

[@allanroberts7129]

I am very disappointed in you and your approach in this video for 2 reasons. 1. Bad application of frictional forces. The coefficient of friction provides the angle at which sliding begins and the maximum frictional force generated REGUARDLESS OF CONTACT AREA. Surface area cancels out during the calculations resulting in the UNITLESS (static and dynamic) coefficient of friction between two objects. Yea, you can use it as a scare tactic to encourage drivers to be safer, but it undermines our trust in you as a creator and as a person. 2. Bad application of recursion and nash equilibrium. The police officer has no incentive to contemplate how fast you think you can go and, honestly, doesn't care at all. For them, it is a balance of time to give a ticket, preventative risk assessment, and impact (cost to the driver). If the risk prevention is high enough (reckless driving reguardless of the speed), then it's worth it. If the time is long (road with little to no shoulder for long streaches or where there are far too many people at that speed proportional to the time to give a ticket), then a driver is likely to get away with a higher speed. I stopped watching, commented, and disliked the video. I get your goals in making this video, but your audience is smarter than the average populace. Use higher reasoning with smarter people, and simpler language for uneducated.

[@yourlordandsaviouryeesusbe2998]

Everything you said it's factual correct, except the last paragraph. That made you sound snobbish. Moreover it's not true at all. Kevin discusses very simple ideas on a surface level in his videos, which any person with an average IQ can grasp with ease. Also, I should remind you that various problems related to coefficient of friction are discussed in highschool physics, so it's not something very complex too understand. At least in my country it's that way.
