The majority of us do not want self driving vehicles - yet all manufacturers continue to chase this concept. For those who don't like to or cannot drive, take a taxi, train, bus, if you have the money hire a driver..
Even once the systems are developed further, putting your life in the hands of a computer program which will always have bugs and may not have your survival at the top of it's list of priorities is not a good idea.
I suppose it could be said that those who make such a poor decision as to trust one of these systems and pay the ultimate price are victims of natural selection.
