I did a 300 mile round trip yesterday. I had to disengage FSD(S) multiple times, mostly for minor reasons, but one time it tried to change lanes in heavy stop & go freeway traffic with very low gap between two cars. Sadly I could not provide feedback at that disengagement.
But other trivial disengagements were in interesting scenarios.
1. FSD(S) is very aggressive in not being in the left lane. On a freeway with two lanes, its always very happy to be on the right most lane (as it should be). But in a 3 lane freeway, it mostly prefers the middle lane. However, my goal was to be in the left most lane which is a carpool lane. But FSD somehow does not realize its a carpool lane and kept trying to get me to the center or righter lanes.
2. In a couple of places, when the speed limit changed due to construction later in the night, FSD(S) would just drop my speed from 70 to 55, when the traffic was flowing at >70. This got me a couple of honks due to the abrupt slowdown in a center lane.
3. In at least one case, FSD(S) was too late to shift to the right lane and with just about a quarter mile to the exit, i had to take control.
But otherwise its been great. I like that its very cautious at stop signs and very humanlike by creeping forward after a stop sign and then accelerating. I have acceleration set to chill, so I did not see any of the hard acceleration that many complained about.
