text: Finally, automated cars increase safety due to the concept of redundency. Since there are two capable operators in the vehicles, (that being the human driver and the car itself) one can take over in case the other fails, such as the car taking over if the driver falls asleep or the driver taking control if one sensors has a malfunction. This redunency improves safety as both systems have to fail instead of just one in order for an accident to occur. This redundency is why commercial aircraft have an extremely low likelyhood of failure, as the plane has both human redundency (two pilots in case one becomes incapacitated) and mechanical redendency (auto-pilot kicks in if both pilots become temporarily unable to address all the issues occuring in flight as well as back up systems in case something like electronics or pneumatics fail).
