A little girl was killed by a car in Toronto the other day. Maybe it happens more often but this one made the news because her parents are politically connected. The question is always asked ‘how do we prevent these tragedies’? The answer is self driving cars. It is not so much that self driving cars would have better reflexes though they probably would. It has more to do with self driving cars moving slower. If the driver is not in such a hurry to get out of his vehicular prison then there is no need to drive fast. Slower speeds not only mean that the car’s computer has more time to react, it means that the child and the adults around said child have more time to get the child out of the way. It also means that when an accident does happen there is less vehicular energy available to do harm to the child.
