Thanks for doing this, got 12.5.6.3 on my wife's new Model 3 Highland several days ago and have to say I am very impressed with the performance. Not perfect yet, but getting there! Haven't had a chance to take it on the highway yet, so appreciate your review.

You are still the best! The only other person I watch is Chuck Cook, and he sometimes gets too much in the weeds for me. So, you are where I go to actually learn something, and not just be entertained. Keep it up. I’m an 85 year old male living in Raleigh driving a 2020 model 3 with hardware 3. I believe that FSD is extending my mobility so much that I am willing to take longer trips and just go more places and still feel safe. So keep up the good work to help me keep up with what’s coming.

Thanks for sharing your experience, and thanks for still doing HW3 FSD drives since those are the ones I’m most interested in.

Great analysis, i've using this version 2 days now and def huge difference

Great video! I’m in Maryland and haven’t used FSD much.

The toll thing is interesting on the Parkway or Turnpike... EZPass vs Full Service... in theory you should be able to preset it to say "I have a tag so choose EZPass" since they are ubiquitous.

Was waiting for this! Thank you BT!

Installed this version just before my drive from Fort Worth to the countryside south of Austin. Highway driving on interstate was much smoother. Merges and overall behavior were much better than the old highway stack. Where I saw the most marked improvement was two lane country roads with speed limit 50 to 60. It used to always go slow on these roads and last night it was about 2 mph over speed limit which was near perfect for the driving conditions. About 40 miles on those type of roads. We have road ridges in our median stripes. It did hit median stripes about 3 times on tight curves. That is the only gripe I could give it. That last 40 miles I usually just take over or constantly hit acceleration to push the car to acceptable speeds. None of that last night.

What amazes me is how Bad my 1 year old tesla works in Europe on motorways(HW3). And now looks like only HW4 vehicles are getting the end to end NN on motorways.

Hi from the UK

Great video

Very pleased with this outcome as a Tesla investor, owner and fan. Great review as always Black Tesla. Good job!. Just wish I could run this on my car here in Scotland. So envious.

It's not 'game changing; until it's unsupervised. Yes, it's egding slowly towards that goal, but it's still a very long way away, maybe a decade and another breakthrough in hardware or AI network design to get there. Let's not pretend that we're just around the corner when we aren't. Sure, it's amazing, but it still does things that are unacceptable.

I don't know about his upgrade? My car does not go the speed limit. If I am at a 40 mph zone my model Y is going 32 miles. Same on a 25mph or 30mph it is always way below the speed limit. why?

This would be a great update for HW3. 12.5.4.2 has been way better for me than the previous update.

Nit picking here, but this drives me nuts. There's no such word as "irregardless". It's "regardless". The prefix "ir-" means the same thing as the suffix "-less", making it redundant and, as a double negation, reversing it's meaning.

내년에 fsd 계약 맺자....그러면 천슬라 까지 다이렉트로 가는 거다.

What are y’all driving? I’ve had this a few days and multiple drives around town. Horrible! Requires lots of interventions and takeovers. Dumb lane changes. Gets lost in the parking lot. Timid. I hope they get this stuff working. Not impressed. How are you being so complementary?

thanks for the video.... v13 soon ?! cant wait to see the improvements (or regression lol)

With no real max speed - hard pass. Not for me ever.

Nice. This build is great for me too. (Also HW4 Model S in Morris County, NJ). The big test for me: From 280 Westbound, to 287 Southbound...to Route 10 West. There is about 1 mile where the car needs to get over several lanes to get on to 10 West....previous builds failed about 70% of the time. This stack? Has not failed yet.

So smooth at the end, maybe it assumes that you’ve gone to sleep and it’s looking for a safe place to park to take care of you. Interesting strategy. 😂 who knew?

It still thinks backroads are 25 when they’re really 55

I had v12.5.4.1. A couple days ago I updated to v12.5.4.2 on my 2023 M3p. Both of these version on my car has a lot of phantom breaking and in a couple areas it is extremely harsh. I can’t trust to engage with passengers and I have to keep my foot on the pedal to counter act 47mph to 8 to 12 mph. I always keep an eye in the rear view mirror so I don’t cause an accident. Seat belts even tighten. I would guess this version is very slightly better. I have Teslogic App and these versions of FSD have the “Motors Power, kW in the App Surging then dropping off all the time pulsing the car. I know the TEAM with get this AI3 going.

Really good point made at 24:00

Merge behavior has needed improvement. I like the way it handled the merging

I've been using the scroll wheel to do the car down to an appropriate speed through to booths to send Tesla a signal about what the correct speed should be. That's been working pretty well.

15:20 so impressive

We are all crazy with the speed! When we are truly not driving and not paying attention we don’t need to worry about how fast we are going. You’re not picking 2-4mph!! That’s crazy. And the car doesn’t need the lane markings. It’s using all the photons in all the cameras. It’s using the lines as well. The cameras detect the road markings way better than the human eye can see them with sun glare.

if it's good for you, then it's perfect for everybody else

Love your ranking system! Idea - invite a professional car service driver along with you and get their reactions. It could help augment their professional level vs replace.

Has some problems going the opposite direction out of driveways from what the navigation shows. On the highway it’s fantastic. Stops too hard on yellows that it could go through and a high risk of rear end accident IMA. AI4 in Bethlehem Pa.

Good vid

Thank you for this informative video. I just got 12.5.6.3 on my car and this helps me know what to expect.

Well done! Easy to watch / listen to.

Great video as usual! I love the new fsd build as well, but when it comes to school speed limit signs, which here in TX have flashing lights & signage Indicating 20/25 mi/hr when kids are present. I’ve yet to see fsd handle this event. Does not slow down at all. I have to usually disengage when I come across that. I’ve sent numerous recordings in, & hopefully this will be addressed soon. Thx

I like your measured reviews but I see some major issues that are basic to fsd and should be solved already. 1)High speed on exit ramps. I had to brake hard to avoid rear ending lead car stopped at light. 2. Tailgating. Follows lead car on highway too close for my comfort 3. Still some basic issues being in wrong lane (eg right turn only when you want to go straight) on streets. I do see improvements like 100pct compliance w/signaling, passing behavior etc. Sometimes my drives remind me of "Jaws".. Just when you feel safe....(fyi, I am driving in CHILL)

I wish I had a HW4 vehicle man, it sucks how quickly my new car with HW3 got outdated lol. So far 12.5.4.2 is kinda awful on HW3 ngl. And still no e-2-e on the highway for us yet. Still cool to see the improvements though. I just wish they gave out the free trials when people got FSD 13 or at least when end to end on the highway came out for everyone lol. They always give them out at the worst times.

Travelled these roads many times, Rte. 280, GSP, 78, Rte 24 & and Kennedy parkway, Old Short Hills road and the Livingston mall. Really amazed how well the Tesla on FSD did! Believe me, it can get confusing when exiting 24 near the Short Hills Mall. We miss our exit all the time. Great job Tesla and Black Tesla. I always enjoy your videos. I would like to see how this version does in NYC. Cheers!🍺

I agree with your assessment. Uber Black.

I think I'm still at 12.5.4 Anyway I was using FSD today and it pissed me off. The exit is approaching and it's sticking to the left lane. I use the turn signal to tell it to change lanes. There is huge gap where it can merge. It begins to merge then it backs off like a terrified driver. It has done this the last time I used it. It starts to change lanes then for no good reason it aborts. It makes me look crazy. Did they fix that?

That white car at 27:49 was sticking forward too much. FSD tends to 'avoid' those kinds of situations. This time by letting white car go.

FSD is awesome!!

That highway driving was phenomenal

How fast these updates are coming out is what amazes me more...

I Love your videos thank You for being here 💯💢💥💫👍👍👍

"Levels of confidence are through the roof." "Levels of comfort are through the roof." I never thought I would hear you say these things! But it just shows how much FSD has improved to the standards you expect. So exciting! I'm about to place an order for the Cybertruck with FSD. Lots to consider. Always love your videos. I will watch for your next one. Thanks for showing us all the progress for I don't know how many years!

Ok awesome video..... I am bit distracted maybe, but what is up with the Sears, did Sears go out out business like 10 years ago? 🤣35:39

hahhaha the point you mentioned everyone slowing when a police officer already pulled someone over is HILARIOUS, cause I actually speed even faster cause like you said "its not like the cops going to get in his car and try to chase you down" -- sure he might call you in to a patrol up the street, but Id just speed momentarily faster on the principal that I hate cops :)

Great video. I think you caught the essence of 12.5.6.3 perfectly. I have also received it recently and the improvements are subtle but significant as the big problems disappear. Very nice job!!
