The whole X debacle has proven once again that Elon will never give up on a bad idea that he has tied his ego to or that was shut down by people he dislikes.
These are exactly the kind of idea that he will jump at once the opportunity arises and the pesky naysayers aren't in the room; "why should we have to bother with any of this privacy or informed consent stuff" is where he's coming from.
Probably shouldn't call it self driving when you its just a level 2 feature that requires full attention of the driver to use safely. See the confusion. When I think of self driving, i think of level 3 or higher standard where i can safely not pay attention to the road. I don't even think any of the other manufactures who have L3 cars on the market call it self driving.
