I currently have a rental car model x with the full self-driving feature.
Europe is absolutely right to ban this. It is scary, and dangerous. I have had this car for a week, I have tried to use FSD on every drive, and it has tried to literally kill me on every single drive. I've never gone more than about 5 km without having to take over to prevent a collision. And that's not even talking about the fact that it can't handle playground zones, or yellow lights. And all the other uncomfortable things like coming to an abrupt stop in the middle of a freeway for no reason.
What's really sad, is that I have a model S with autopilot at home, and I love it. It is not self-driving, but never claimed to be. It works very well, it does lean centering and adaptive cruise better than anything else on the market. How they got it so wrong when they went to FSD I have no idea!
