Impossible standards are equivalent to bans, and zero deaths is an impossible standard. All of the companies that are testing self-driving cars have had accidents with other cars and pedestrians. Some of them resulted in death. Others did not, but easily could have, and eventually their luck will run out and they will also cause deaths. Who would invest millions of dollars into developing a technology when a single mistake could flush all that money down the drain?
