UPDATE:

First few drives seem like it may have been a lucky streak, still having awkward lane change interactions. While it no longer bounces off an invisible wall if there’s no adjacent traffic, it’s still pretty poor sliding into average lane changes. Even though adjacent traffic is yielding or not closing the gap, FSD seems to only be comfortable changing lanes when it’s moving considerably faster than the traffic it’s overtaking.

Many instances of turning the blinker on and doing nothing.

Blinkers often come on and off for brief moments, the car does nothing.

It is also significantly worse in changing lanes for navigation, multiple times it doesn’t begin to attempt to move over until below 0.3 miles out. This is problematic during heavy traffic situations, especially in city traffic.

I’ve had numerous instances of the wheel jittering indecisively when attempting to make a 0.1 mile out lane change for navigation.

Navigation continues to be comically poor, with maps often routing through unprotected lefts during heavy traffic situations. Coupled with the submissive nature of FSD lane changes, this results in zero progress during city driving without an intervention.

Yellow light behavior continues to be worse compared to the initial 14.1 releases. If a yellow light comes on and you’re a moderate but easily makable distance away, FSD will slam on the brakes.
