But sometimes you do want to drive into a wall. If a child runs out into the road too close to brake and you're traveling 35MPH, the result of driving into a wall is liable to be whiplash for you and a bad scare for the kid. The result of not swerving into the wall could be a criminal investigation for you (plus a civil suit) and death for the toddler. Aviation tends to have fewer trolley problems than driving does.
