I realize this is blasphemy, but a few weeks ago I tried to watch a NASCAR race being run at Talladega. I lasted about five minutes before terminal boredom overtook me. It appeared to be nothing more than a high-speed freeway commute--a mob of luridly painted, identical lumps of metal loping at 180 mph around the banking, fender to fender, nose to tail. Knowing the scenario would surely devolve into a multicar demolition derby that would thrill the goobers in the grandstands, I turned off the set to later learn that this time it was Jimmie Johnson who triggered the eight-car melee.
