The only place where you hould race is on a closed track. Against people with similar cars. That's the only way to tell who is the better driver.
I can drive 240 kmh on a normal road as well, i can race my 250 BHP car on the streets, but it doesn't make me feel more important, and it will not give me a kick.
However: racing in a 140 HP Renault against 40 other people at the same time on a closed circuit with only a few seconds between all of us....now that's a kick!
Street racin is stupid, dangerous, immature and doesn't proof you are a good driver. All it may proove is that you have the money to build a fast car.
