I'm occasionally still amazed that traffic works as well as it does. I must say I'm hesitant at using this example to claim that people are more capable than you might think. Driving is just something humans happen to be competent at. There are plenty of things roughly as complicated as driving a car that people aren't surprisingly good at.

This also reminded my of something people said at the latest meetup. At least two people told me they had deliberately tried to get more scared of driving, because they had noticed they had less fear in a car than on a plane despite planes being safer.
