If he had time to notice it not slowing down he had time to brake and take it out of full self driving. I understand as someone who is sceptical about the fsd mode that I am more proactive at taking over than those who trust it a little bit more. I just feel if a company tells you to supervise it you should supervise it.
I still find fsd to be very finicky and vastly oversold
Just some insight from my pov. Fsd is marketed as FSD (Supervised). I don't agree with the jamming but it is what it is. I know it does janky stuff, it still forces you to pay attention. Do I believe this could happen, yes but do I doubt the driver always until proven otherwise.
I have had my model y yell at me to take control when I was already out of any auto/fsd mode. I have many downs and many ups. I agree that the car should actively steer you into the train. I was curious if anyone had a link to the dash footage or even to an article with it.
