"And it tried to stop us in no man's land. Insane. Anyone seeing this behavior would have thought I was drunk. So next time something like that happens if I'm in FSD mode, I'm going to cancel it by turning the steering wheel slightly and taking over fully."
I won't say this happens regularly, but it certainly has happened to me several times over nearly five years of Tesla ownership. You always have to be ready to take over control of the car in FSD in an instant. It is nowhere near being a license to ignore the road, traffic, and surroundings. I hope to see that someday, but we're not there just yet.
