If you kill someone. Intentional or not, you will most likely serve jail time. are you telling me that if all vehicles were driver-less, there would cease to be any sort of jail time for any death-related to an accident?
This is categorically false. The VAST majority of automobile accidents that result in deaths, even though drivers were at fault do not result in jail time. Even a large part of DUIs that result in deaths only result in community service and probation.
