I would like to add;
Over the last year I have put 1100 miles on my C5, yet pay more for my annual license tabs than for my commuter car which is heavier, so actually puts more wear and tear on the highway system, and runs up 15,000 miles per year.
Now that I have a second bike, I will probably ride each one about 600 miles (more I hope) and pay a double "motorcycle tax".
I don't mind reasonable taxation since it funds many important things, but this is just wrong.
