Fsd is really sketchy. It either works like a dream or wants to kill you. It’s why you have to agree to a disclaimer when using it otherwise it’ll disable.
Autopilot if a fancy cruise control. It’s pretty solid but appears to have an issue with fire trucks. I know of one fatal accident where it drove into a firetruck without enough time to react. Tesla should be liable for that. Their product failed and they removed the radar that would have prevented that scenario.
I haven’t seen the video you are mentioning. It would be stupid for them to market that as a current feature. You must keep your hands on the wheel at all times in fsd. It might accelerate you full speed into oncoming traffic and the car is fast
