I use FSD for at least 600-700 miles of driving per week, with most of those miles being on highways and freeways.
For my founders AWD, I can say the only of your issues I've had a couple times is FSD waiting until last minute to try and switch on ramps, but doesn't get there in time so the exit is missed. It does tend to wait way to long in my opinion to prepare for freeway exits or freeway changes.
And maybe once or twice in a very long time I've had it switch the wiper back to auto in FSD. But those times the window was filthy and I can't really blame it for thinking it was rain, etc. obstructing the front camera.
