Your are generalizing over what is probably just a lack of skill set on your part.
Last year I was driving into work when I saw a chevy tahao (sp?) with the woman drivingit and talking on her cell phone change lane sharply, it was rush hour traffic and literally run over a guy on a sportster with the side of the suv. It knocked him down, part of his bike and his arm went under the rear passenger side tire. As in the case of this man it is not usually the rider, but someone or thing else that kills him. Unless it is a closed coarse or something of that nature riding a motorcycle is to unsafe IMHO.
As for skills I rode dirt bikes for 5 years as a teen. I liked it and would like to take it up again, but I would never ride on the road.
