Reiterating on a current theme here at Red Planet Dust about our human abilities have a look at interview with Cass Sunstein, Professor at Harvard.
A guy is driving his Rolls Royce (!) down a nice lightly bending lane with cars parked on his side of the road somewhere in England. He notices a car parked a little further ahead preparing to drive away. To warn the other driver he flashes his big lights several times and to his terror he sees the car pulling up to the driving lane were he hits the car midway.
