Well drove 150+ miles yesterday mostly highway and found very little difference on 25.1.
I knew as soon as I used the on ramp there would be no magic today. A major problem for me is when merging into 25mph-40mph rush hour traffic behind a line of cars entering the highway. As the cars in front of me match the rush hour traffic and merge into traffic FSD sees empty ramp space and increases speed passing rush hour traffic. That is stupid and what typically happens is FSD begins to run out of ramp space and would have to do a nasty merge. Knowing what FSD is doing I almost always have to disengage. Merging with highway traffic at higher speeds has worked "reasonably" well for a long time.
My other major highway problem is when FSD wants to move into a passing lane with a car fast approaching continues. I just cancel the move.
I'm hoping V11 will address these types of issues. With these 2 problems resolved my highway driving would be 99% intervention/disengagement free.
My 10 miles of city/street driving was surprisingly good.
