What gave you the notion that Fuel taxes were anything other than a money grab? As we move towards renewables, there will be no other way to feed the monster than a mileage tax. It is a certainty.

I didn't say they were. But they're also another excellent reason, as far as I'm concerned anyway, to drive a fuel-effieicnt car :)
