14.3.1 First Impressions

[CyberLucky]

I've spent about an hour with FSD 14.3.1 so far. Early thoughts:

What's gotten better:

• Yellow light handling is much improved - no more slamming on the brakes to stop for a yellow it should have gone through.
• Getting into a lane well in advance of a turn is much improved - I haven't missed a turn yet (this was an issue with 14.2.2.5 - it didn't even try sometimes to get into a needed lane).
• Speed profiles are slightly improved - unlike a lot of others, my issue has been that no speed profile will reach the speed limit - they all accelerate until they are 3 or 4 below the limit and stay there. Yesterday, "hurry" got slightly above the limit - fantastic! But I'd still gladly downgrade to a version with actual max speed control.

What's the same or worse:

• The dangerous hesitations that first appeared for me in 14.2.2.5 (one of which happened during a left turn into oncoming traffic when FSD decided it couldn't make it and just stopped halfway into the oncoming lane with cars fast approaching) continues in 14.3.1: yesterday while waiting to make a right turn to merge into traffic an oncoming ambulance resulted in FSD's hesitation behavior: it lurched back and forth a little farther into the path of the ambulance until I had to give it the go pedal to get out of the way. My wife has similarly experienced the indecisive lurching.
• Disengagements remain much higher than 13.9 (which I almost never disengaged).
• Navigation issues remain probably the weakest part of FSD, which has started ignoring the map more often, usually to its (and my) detriment.
• Not sure yet about FSD's habit of switching to a lane that's about to end, right before it ends - more testing needed.
• Phantom wiper issue still happens, but much more infrequently. I don't reflexively turn off auto wipers simultaneous to engaging FSD.
• It couldn't get out of my garage and onto the road. It backed out, went forward a bit, the backwards, then forward. Then gave up. I have a straight driveway with the garage at 90 degrees; this hasn't happened on any prior version.

Overall this version feels smoother and more assertive, except for the very occasional hesitations. I've been using FSD in Cybertruck for about 1.25 years; 13.9 still feels like peak FSD to me, despite the lack of parking. But we're getting closer.

At this point, most of us will never see 14.3.1.

I got 14.3.1 the night before last. Is a subsequent version already rolling out?

I don’t see how unprotected left or right turn will improve as Tesla can’t see that far. This is my biggest question for unsupervised.

Unprotected turns have been perfect for me until 14.2.2.5. I don't think the visualization on the display reflects the range limit of the cameras, if that's what you're using to judge it's range. Pretty sure they limit the display to reduce unnecessary info.

I'm convinced they'll get to unsupervised - prior versions have been mighty close - but 14.3.1 isn't dialed in (and I think more generally the 14 series is on a new stack that will have some teething pains as they calibrate it).

But it's a reminder to me to pay attention - I've gotten so used to trusting the truck.

One thing I found myself doing is I turn off fsd as I approach intersections. The deceleration and acceleration is too extreme. If making a turn, I usually ease off the accelerator half way through a turn (especially left-handed) to reduce the inertia lean, FSD just keeps the accelerator and it's just less comfortable.

Yep. 14.3.2. tesla-fsd-v1432-unifies-fsd-models-across-robotaxi-and-customer-vehicles-improves-summon-and-adds-new-menu

It is crazy how many different variations of peoples experiences with FSD is. Tesla really needs to fix this. If it is same hardware and only using vision only, experiences should be identical (especially for normal driving circumstances)!

Insane. You're the only person coasting through turns out there.

I've come to the conclusion that 99% of people's complaints about FSD are subjective takes.

Indeed, these reports ARE subjective takes. Drivers have experiences and some report their experiences. The different experiences make the reports interesting and useful.

Just an example. Standard right turns. Cross 2 or 3 lanes vs the standard closest lane.

A lot of people demand and expect perfection 100% of the time in a completely imperfect world, and thus will never be satisfied in any meaningful way.

Probably, but FSD itself seems subjective or even random at times. Hurry mode for me runs between 9 and 14 miles above the speed limit at 60, sometimes it doesn't reach the speed limit which others report as well. Sometimes I blow through yellow lights, others it hard brakes. It will either turn left to my office and cabin or blaze past the turn. I only use it 40% of the time and it is moody.

That is interesting and useful.
