ELI5: What's required of a NASCAR driver to succeed, aside from turning left? How does one overtake another driver instead of being doomed to last place or second place?

The driver who can draft off the other cars in the pack to save fuel and can get around the track without scrubbing a lot of rubber off his tires has a huge advantage over a driver who might be able to drive just as fast but needs to pit more often or under worse conditions.  This ability to drive efficiently combined with the instincts and aggression needed to take risks when they have a good chance of paying off are what separates a good NASCAR driver from an average one.
