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

I feel that this version of FSD is worse than the previous.

FSD works great. Autopark a mess. has no idea keeps pulling in and out and then kicks off your FSD. Waiting for next version to fix. Tesla is aware.

It’s interesting that the behavior is different from car to car. I have a 2017 75D HW3. FSD 12.6.4 works pretty well on city streets and Highways. The issues I have are: 1) last night it ran a stop sign making a right-hand turn. Sometimes when it turns into our subdivision it drops the speed to about 10 mph and it’s hard to get it speed up. On a positive note, it did drive into my driveway once but it won’t do it again.

FSD 12.6.4 is working extremely well for me. I'll reserve a 5 star rating for when it works unsupervised. I give it a strong 4.5 stars (for my needs).

Using Hurry versus Standard eliminates the nagging lane changes

Seems to be slightly smoother than last release. I found i can minimize lane changes without the removed button by simply dialing the speed down with the scroll wheel. Still no where near L3 since it misread speed limit signs and traffic signals at times

Highway, interstate driving 5 stars. City driving, especially at night, 1 star. It looks like the small brain of HW3 can't fit both a good AI code for highway and a good one for city. Instead, Tesla opted to improve highway and let city driving skills deteriorate. Update: I did plenty of night and city driving yesterday and the weird stops are gone. The car is cautious on poorly lit streets and drives 5 below limit but drives well.
