Considering that there have been accidents and deaths involving driverless autos, more research needs to be done to insure that the faults that resulted in these accidents are addressed. Also important is the reality that GPS is not always correct, so there is no guarantee the auto will end up where it is supposed to be. I've been driving Uber for 2 years, and not a week goes by that the GPS does not fail to malfunction, the app, malfunction. These things are what the driverless car will depend on. I don;t think it's ready for prime-time which is the reason the driverless tests were halted after the last death.
