Which us why self driving cars are better for all road users.... They won't drive at triple the speed limit.
I don't get why people think they wouldn't do that
In fact, in a world of self driving cars, I don't see why we would need a speed limit. The car can be trusted to drive within its own limits..
And if your dad had a self driving car, your brother could have helped your dad to the car and told the car to drive to the hospital.
and his brother could have told the car that it was an emergency (destination: emergency unit of hospital) and the car could have decided to drive at its maximum speed, broadcasting to other vehicles that it was doing so.
A journey such as this might attract some official attention, but assuming that the hospital corroborates the story of an emergency, then I don't see why there would be any charges..
