its censored because the game really can't tell if your name is "scooter" or "URAcooter" or "iluvcooter" or "scooterminusS" or any number of other variations.

"but i meant it as the vehicle" - how is the game supposed to distinguish between that or any of the others?

Sure, it blocks some legitimate names. Bummer. Come up with a new one and carry on? I certainly appreciate steps taken to avoid seeing names like "dickriderpro."
