I will copy this right from my Google website.
I will prove to you that NASCAR is a sport. Wanna see proof? Taken directly from my AIM profile: (NASCAR) is a sport! And yes, the drivers are athletes! And no, not all NASCAR fans are rednecks! I am tired of everyone thinking it is not a sport, thinking the drivers are not athletes, and thinking all fans are rednecks!
P.S. It gets over 140 degrees in the car! Drivers can lose up to 10 pounds of sweat during a race! And they can't go to the bathroom for 3-6 hours! Why don't you try being in a race and tell me the drivers are not athletes!
Taken from answers.yahoo.com:
(It) depends on how one looks at Nascar. There is the Nascar nation that will say yes, Nascar is a sport. There are those that will say no, Nascar isn't a sport. Then there are those who really don't care. Do I think Nascar is a sport, yes!
Want more proof? Well then look at this from wiki.answers.com: I do belive it is. you have to be very fit in order to endure the heat that the drivers have to go through. YES! Yes, its a motorsports, and it could be one of the most popular in the world! That's enough for now.
