You'd have a lot more without driver's licenses.
@Hailinel: The implicit design of something has little to do with how it is actually used. I get enjoyment from running a slick ar15 in 3 gun competition the same as a porche gt3 owner gets enjoyment from taking his car out on track days. An irresponsible or unstable person could use my 3 gun rig to hurt or kill people, and irresponsible person in a porche gt3 speeding on a highway could cause an accident and hurt or kill people.
Excellent point. Everybody on the road has a driving license (hopefully), but we still have accidents and drunk driving deaths all the time.
