Why do you suppose Uber created a reputation system and vets their drivers? They certainly weren't required to, but they profit from reducing asymmetry because consumers want to know their ride will be a pleasant experience. Mandating the features Uber voluntarily chose to add will only hold future competitors back when some new type of technology moves beyond our existing capabilities. And good luck removing those regulations once those are in place. You'll have powerful companies like Uber fighting tooth and nail to keep competitors out of the market.
