I let FSD drive a couple hundred miles yesterday, combining interstate, medium-sized city, small city, and suburban roads. Compared to 14.2.2.5, I found it to be a mixed bag, but generally favorable. I spent the majority of the drive in Standard mode.
POSITIVE:
Lane change shyness is finally addressed. On Standard mode, it's just shy of aggressive. It felt perfect.
The only brake stuttering and jabbing seemed appropriate for the situation (a pedestrian with unknown intent, a large bird flying directly in front of the vehicle).
It feels like the car is generally more confident and makes decisions quicker. There was even a difficult unprotected left-hand turn that it handled about as well as it given the camera locations and oncoming traffic obscured by an opposing left-turning vehicle. In this case, it had a slight moment of indecision with the steering, similar to a human trying to see around the vehicle. But it did not stop in the middle of the turn like I've seen it try to do in the past. ** Side note: FSD would benefit from extra cameras to mimic our human ability to move our point of view left, right, forward and back.
And finally, unlike some reports, I had no issues prompting a lane change. The only one it ignored was when another vehicle abruptly moved into the lane next to me right after I signaled, which was correct.
NEGATIVE:
There was a lot of hammer lane camping. I had to prompt movement to another lane more frequently than normal, and there were a couple times I knew that vehicles going around me were probably pissed off. Sometimes, FSD would move right when another car was coming up on it, but sometimes it wouldn't without a prompt. Having lived in Germany for a while, I'm used to only using left-hand lanes for overtaking vehicles. You pass and then move right back over. Failure to adhere to that is dangerous. I've seen complaints in the past about FSD changing lanes too much, but these are the conditions where it SHOULD be changing lanes. So I think this could use some tuning.
Parking is less accurate. I wouldn't say it downright sucks, but even my stop at a supercharger was not centered. It was between the lines, but barely. There is room for improvement here. Parking is one of those cases where the intelligence of FSD should be combined with processing and logic. In theory, a Tesla should be able to park much better than any human. In practice, it just doesn't.
I had multiple critical disengagements in a row through a construction zone. After stopping at a flagman for a while, FSD started to continue forward while the STOP side of the sign was facing us. Traffic was diverted into a single lane (left lane), but FSD tried to move back to the right lane twice while going through the zone. To be completely fair to FSD, this was one of the worst-handled construction zones I've seen in a while. The flagman kept twisting the sign back and forth, and the moment FSD started to continue to move forward happened during a twist and when he moved his body in a manner that looked a little like he wanted us to proceed. Maybe FSD would have stopped again on its own, but it wasn't safe to find out. Within the zone, the right lane that we had to stay out of was not marked at all, and the only indication was the presence of construction vehicles that were moving in the direction of our traffic. Even I wasn't completely certain when we were supposed to move back over until I spotted the second flagman.
I'll have more traveling to do tomorrow, so if there's anything noteworthy, I'll post again.
