Link to statistics page for that 90% please. Otherwise, you are just pulling a number out of your ass.
Tell this guy that almost all motorcycle wheelie crashes are from old fuckers pulling out in front of them.

Or this total asshat:

When a person crashes on the freeway on a bike, the surrounding traffic has about 2 seconds to respond defensivly....If that. So if the guy passes a car, doing 85mph, and wipes out right in front of the car....Then you want to blame the guy in the car for running his stupid ass over? Please.
As someone else here said, there is a time and place for everything...The freeway is NOT the place. It is unsafe at best, and deadly at worst.
Why do you think when a person crashes it's called an "accident"? Because they didn't MEAN for it to happen....As in they lost control of their bike someway, somehow. Accidents happen...Even to the most experienced riders. Look at Evil Knevil. Dude broke almost every single bone in his body in different motorcycle accidents. Granted, he was doing....gasp....stunts.

And he was one of the most experienced mofo's out there......so don't say it will never happen to you because you're too good for that.
Riding a wheelie is ASKING for a few things...The least of which is a $1000 fine, and the worst of which is getting yourself killed.
