Is NASCAR really that hard?

[cata1yst]

This topic came up for discussion last night before heading out to the bar. I basically told my group of friends that I don't think driving in NASCAR looks very difficult. No one came up with any responses that made me change my mind. I have been to one race a few years back. It was a fun all day party, but I didn't and still don't understand a "driver's gameplan" besides going fast and trying to pass people.

What makes NASCAR difficult? Endurance? Strategy?

Someone enlighten me because I still think I could be a pretty damn good driver.

With that said...how would an "Average Joe" do in NASCAR?
