FSD now either hugs the yellow line on the driver side OR attempts to cross the line.

Significant upgrade to FSD. Driving style on freeways has significantly faster and safer lane changing behavior and much better ability to stay in lane on curves at higher speeds. Still needs work on reducing incidents of premature lane changes when incorrectly anticipating faster speed in adjacent lanes by failing to recognize slower traffic ahead.

FSD did two stupid/illegal/dangerous things on one drive. It attempted to turn into the opposing lanes of traffic on a divided street, I had to stop and reverse to get around the barrier and back into the proper lane of travel. It tried to anticipate a light turning green and almost got me t-boned when it started to turn in front of oncoming traffic. Two legitimate disengagements in less than 5 miles. When is Tesla going to finally figure simple rules of the road out?

Almost hit another car from behind, made a left turn in front another incoming car, stopping or slowing down for no reason.

This FSD update feels worse than the previous version. It struggles to maintain a consistent speed, frequently slowing down and speeding up. When turning near a bike lane or solid white line, it dives into it—something the last version didn’t do. At 4-way stops, it accelerates too quickly, feeling like it might run the stop sign. The only pro is that the random braking before green lights seems nearly eliminated.

This is a good update to get for HW3, although it does have it's quirks too. To start, it now properly takes the correct lanes on my drive home and doesn't miss the exit anymore. However, it seems like it's attempts to search for the turn lanes have broadened and this causes it to occasionally take the turn lane before the correct turn lane. It does typically correct itself, but it's rather dangerous when the roads are busy.

FSD keeps getting better. This is the most human-like version I have had to date. I rarely have to intervene. It is getting closer to being suitable for robotaxi it seems. I look forward to getting my HW3 updated to HW4 so I can use v13 and beyond

FSD 12.6.3 fixes most issues with 12.5 builds, and is incredibly smoky and confident!
