You guys know what will happen next don't you? Since a tremendous portion of the price of gas is actually federal, state, and local taxes, all the agencies will find a way tax bike riders. I saw a little blurb on CNN or Foxnews, don't remember which about some technology that was being kicked around to charge per mile instead of per gallon. High fuel efficiency cars get in the government's pocket, so what they were proposing was a way for the fuel pump to interface with the car's onboard computer to see how far you'd driven, thereby adjusting the price per gallon. The guy that drives the 10 mpg gas hog would get gas for (these numbers are examples only, don't take off on a tangent) say $3.00 per gallon for 20 gallons, but the guy with the fancy experimental hybrid that gets 200 mpg would pay $60 per gallon, assuming they both drove 200 miles between fillups.

We as riders should take care, as we demand more bike paths and what have you, the government could and probably will start insisting on registration fees and other use taxes. You could find your favorite bike path suddenly has a toll gate at each end.
