a modern cruise missile can navigate to its' target from hundreds of miles away, with external guidance, and can 'wander' to delay the approach to its' target, skimming the barely 100' of the the tree-tops, then resume course &amp; hit a target the size of a car WITHOUT FAILURE. way more difficult than driving a car. skilled, experienced pilots have tried to just FOLLOW a cruise missile in a flight simulator... IT CAN'T BE DONE. the computer can fly MUCH better than a human. autonomous flying has ALREADY been done.. and autonomous driving WILL  be done on cars, much easier than flying.
