One has to wonder what will happen 20 years from now when all cars are self-driving.
Will it be against the law to be a drunken passenger???
I dare to say yes. It appears the end of this is to stop drinking entirely or create a strong anti-social stigma on it. They already know they can go after anything and say it costs other people money/safety/etc. then everyone will support punishing the ‘offender’ to great extremes. Therefore, abolishing the perceived offense.
