"By using less fuel you are shifting the tax burden onto those who cannot afford a high tech vehicle."
How do you figure? If the sticker price is higher, then so is the amount of taxes I'm paying to roll it off the showroom floor.
Also, your argument is only valid at the leading edge of the paradigm shift to high tech vehicle adoption. Eventually, those brand new 'high tech vehicles' will fall into the secondary markets (e.g., used car lots), becoming more affordable with each resale. It's only a matter of time until we reach the tipping point where gas guzzlers are in the minority. When we're all driving cars that get 100 mpg, then we're all sharing the burden equally.
Fighting progress because it changes the status quo is a losing proposition.
