The overall desire to track everyone is the goal. In NYC, we had a Congestion Pricing plan put forth. The bottom line was that there HAD to be a financial toll, as they wanted to track everyone.

Try this one...index fuel taxes to inflation (not that that number is accurate anymore, at least as issued by the Feds). If you drive a prius, less tax. Drive an Escalade, more tax. Drive an 18 Wheeler, still more tax. Fair, anonymous, and fixes the system.
Oh, I'm sorry. This is America, land of the Oligarch. We have to give this to a private company, make sure that it is enforced outside the court system, and make some Wall Street guy able to buy a west coast beach house as well as an east coast beach house.
