Then you'll need the override when the passenger (or driver) is dying and needs to get to the hospital. I guess you would have to read and sign the 85 page EULA and sign: "I understand that if I crash here there will be hell to pay".
Why would there be such an override system? That's crazy. If there is a need to drive less safely for such a purpose, again, the robot will do better. You push the button marked "Emergency - get me to a hospital" and the robot works out the closest hospital and negotiates with other robots on the road to allow it through at greater speed. The last thing I want in such a situation is a panicky human losing blood and going into shock trying to drive a car as fast as they can.
