why is it that every goof in a new challenger wants to race me?

it depends what type of bike it is. i am not stupid. but my brother had a 2003 gsxr 750, and my awd mitsubishi running 32 lbs of boost used to spank on that bike. all the way up to about 110 mph, then i would let out as i was too scared of the car

Depends on the rider too....most people can't ride. Unlike a car where the most you have to worry about is traction and not missing a car. Bikes have the added worry of balance and flipping under drag conditions. Takes a long time to be worth a damn on a bike.
