Wow, a bit of a hate boner against bikes? Maybe half a dozen people a year are killed by bikes in the US. And why would you want track bikes anyway? Road taxes pay for general funds, not roads. You’re paying for roads even if you don’t own a car or a bike and bikes at least don’t damage roads.
If my motorcycle has to be licensed, insured, registered, taxed and inspected as a road using vehicle, so does your bicycle. The wear a motorcycle puts on the roads is indistinguishable from a bicycle.
Also, in my state, road taxes DO pay for roads.
