Driving while inebriated is illegal, self driving is not.
Traffics jams and erreactic behaviour could be fixed if everyone is in a self driving car, but at that point it woild be far more energy effecient, environmentally friendly and cheaper for society to build electrified transit instead.
If you prioritize the street so that only self driving cars are on it and they need wireless communications to function, how do other road users like cyclists and pedeatrians safely use the street?
Self driving cars are not here to make your life better, they are here to make a handful of people rich.
