The main issue I have with full self driving is that it'll probably never actually be full self driving; there'll always be use cases where people have to take over - ice, snow, slightly flooded roads, sand, whatever*. And humans will have to take over under conditions when it's extremely helpful for them to have had extensive driving experience under a range of conditions - experience they'll no longer have because the car's been driving them everywhere.
* Yes, I know we're not supposed to drive in some of these conditions, and yet sometimes we have to, even if it's just to get to a safer place.
I can't help but think he's saying this now as an attempt to distract from the stories of "Musk has been talking to Putin since the spring when they were both faced with problems: Musk being forced to buy Xitter and Putin unable to steal Ukraine. Odd how Musk has been becoming more rabidly pro-Russian-interests, isn't it?
