Whats the point when your car can't drive you home when you are drunk as fuck?
That, too. It really needs to be hands free.
I suppose this will need 50 further years of development.
Edit: Or other streets...
In this case it is also necessary that "in control of an automobile" is not defined to include sitting behind the wheel ready to take over if something goes wrong. In a world where that phrase encompasses sleeping it off in your car, that will be a difficult change, I feel.
That is the eventual goal, and this is the beta where this is not yet possible.
