Pay by the mile? More states considering pay-by-the-mile car taxes

This is a tough one.

Obviously, as more people start driving electric cars, hybrids, and more efficient gasoline vehicles, the revenue from the "gasoline tax" will be decreased. But they seem to be attacking the wrong side of the equation: creating disincentives for driving instead of creating incentives to not drive.

I've long believed that the way the US Tax Code currently handles "car & truck" expense for the American businessperson is insanely ludicrous: it's OK to maximize consumption as long as he's able to maximize deductions (as in tax deductions). Current tax code allows people to deduct by the mile. This actually minimizes revenue for the government in the long-term, not to mention creates the most damage to the environment / resources of the planet.
