We made drunk driving super illegal and that still doesn't stop people. I would rather they didn't in the first place, but since they're going to anyway, I'd really rather they have a computer that does it better than they do. FSD will pull over and stop if the driver has passed out.
Modern cars could easily detect drunk like driving and stop or call the cops.
If we could ensure that only drunk people use driver assistance features, I'd be all for that. The reality is that 90% of the sober public are now driving like chronic drunks because they think their car has assumed the responsibility of watching the road. Ban it ALL.
