Vaccines don't compare to cars as much since the mere exposure to cars don't really cause injury or death. Unless they're in motion or were in the car while running (carbon monoxide poisoning). Although so many people drive, and there are so many accidents, it isn't an imminent threat to all people. The mere exposure to a disease is often all that's needed to for it to spread to an individual's family and their families/friends and so on until we have an exponential infection rate. This puts vaccines on the critically needed list so the government stepped in to mitigate the greater harm of lacking them altogether. I still think it will be a case of shared blame for driverless cars, although my hope is that blame would be largely unnecessary. If driverless cars can reach the same reliability of autopilots in aircraft, this will save lives.
