Presumably, stepping on the brake or doing manual steering input above some treshold would take the car off autopilot immediately.<p>The opposite problem that the autopilot would have to drive the car off the road is equally hard, or even harder: if a concious driver would have made that decision (ditch the car over hitting someone) then so would the autopilot have to, or it would be <i>vastly</i> inferior to a human driver.<p>That means that the autopilot has to make that judgement and make it very well, since it will involve potentially harming the car and its passengers on purpose. Driving the car into a tree because of misidentifying something that isn&#x27;t a human for a human would be very bad news.<p>It&#x27;s the same deal with wildlife: if a moose is on the road you may have to drive off the road if you can&#x27;t break, but if it&#x27;s just a deer you&#x27;d likely rather hit it than drive off the road. Autopilot would have to do the same.
