Cars are the dangerous thing on road. Banning them would eliminate half of all motorcycle accidents, cite below. Idiots riding without helmets and being intoxicated greatly skew the fatality statistics.

Findings from motorcycle safety study.
75% of accidents were found to involve a motorcycle and a passenger vehicle.
Almost half of the fatal accidents show alcohol involvement.
In the multiple vehicle accidents, the driver of the other vehicle violated the motorcycle right-of-way and caused the accident in two-thirds of those accidents.
The report's additional findings show that the wearing of appropriate gear, specifically, helmets and durable garment, mitigates crash injuries substantially
The failure of motorists to detect and recognize motorcycles in traffic is the predominating cause of motorcycle accidents.
