"According to the National Highway Traffic Safety Association, in 2008, 5,290 motorcyclists died and 96,000 were injured. Motorcycles make up ∼3% of all registered vehicles in the United States and account for only 0.4% of all vehicle miles traveled. However, motorcycle crashes accounted for ∼10% of all motor vehicle crash fatalities, and per mile traveled, motor cycle crashes are ∼37 times more lethal than automobile crashes."
I mean, I'm just poking fun, a lot of my friends and family ride. But it's stupid dangerous.
