I often try to explain this to friends, but in a shorter way: Driving a car is essentially a controlled explosion taking place every second about three feet in front of your face—and yet this very dangerous and messy process "just works" for millions of drivers every day. We are more afraid of other cars than we are of the fireworks right in front of our face. That's pretty amazing.
