nascar a sport???

Alright i turned on my wonderful telivision to watch some football and nascar was on! i sat and watched for a couple laps and relized what do they do any different then any other human we all make left turns at some point in our lives does this mean we can race? there is nothing special about these people their CAR is fast. If any one should be aknowledged it should be the guys changing the tires in 6 seconds thats something impressive!!! i'm just saying left turns in a car not so sure its a sport.
