So it starts, the outlawing of self driving cars. The United States will never allow a car to pilot itself without an occupant. The security risk's far outweigh the convenience for drivers, the technology will be use to make cars safer. Laws will start being purposed to make sure a vehicle always have an occupant. There will never be a day when a vehicle can drive from LA to New York without an occupant. The idea of a taxi fleet with no drivers will never happen, government regulations will prevent it. The technology is good for making an existing car much safer to the point of almost no deaths, that's as far as it will go.
