These automobile analogies are so lame.
But.. It's likely the 'moron' and his vehicle are licensed. In which case at least he had to take tests and prove a MINIMUM level of skill in operating the vehicle and understands the rules-of-the-road.
He likely has liability insurance to cover damages resulting from his operating the vehicle.
Fortunately new cars are very safe and there's a good chance my vehicle will save my life should the moron be involved in an accident with me.
If a person who has never driven a car before were to be able to walk into the car store and drive away with no previous instruction, What do you think would happen?
Hey, "It's Ready to Drive!"
The horse is dead.....you can stop now
