In 20 years kids won't believe people were allowed to manually control 4000 pound machines manually zipping along within mere inches of each other. You are wrong. Book that.
To the people involved, any accident is important. Auto pilot driving only has to take the moron drivers off the road to effect both the serious injury and deaths caused by vehicles downward. I can see a time when the insurance companies will not let a vehicle be human driven if there is ANY indication of alcohol sensed in the vehicle in multiple ways. That in itself would possibly significantly lower the carnage drunk drivers cause. If they manage to lower the highway deaths to 5,000 or lower a year (and that is a tech challenge, not an impossibility), I doubt anyone will be able to argue for personal driving.
