You missed a few points: Going 180mph in a pack of 15 cars while making a left turn without turn signals or brake lights.
Think of it as every commuters worst nightmare.
F1, CART, etc. are all so great too. All those left turns and right turns inter-mingled is awesome. And once every 15-20 laps, someone may actually attempt to pass another car!!!
During the Japanese Grand Prix a couple weeks ago, Finnish driver Kimi Raikkonen passed another driver (Alonso I think) on a very sharp turn with maybe a lap and a half left in the race. I watched the replay at least a half a dozen times and I still couldn't believe it. Hell, jockeys in horse racing don't pass other horses like this, let alone seeing it in motorsport.
The announcer said that pass was worth 100 NASCAR style passes......and he was right.
I respect the skill involved in NASCAR racing, but for my money F1 is so much better it's not even the same sport.
