So what we'll probably end up with is real self driving Waymos all over the place and fake self-driving Teslas that 'self-drive' as long as you're still really driving.
The only real concern I have is whether Musk exploits his position to impact the regulations to push both Waymo and Tesla into a bucket called "self-driving" where they get categorized the same and both still require drivers, essentially using the regulations to knee cap any rival that is ahead of Tesla.
The other side of it is that I think we'd all be very happy if Musk went back to just lying about his electric vehicles.
