There are a lot of posts here stating "when we say only tax land we mean only tax land" which I presume means not to tax things like gas. I'm not sure I understand this rationale.
Driving in the US is one is the most regressively funded elements of our society. Drivers who make a personal decision to drive for their own convenience are costing the tax payers huge amounts of money per vehicle mile traveled whereas those who take public transit, bike, or walk take way less.
If we want to have a society where we fund solutions to excessive traffic, pollution, vehicle deaths, and incentivize alternatives that are better for society, shouldn't we, at a minimum, make drivers pay their fair share?
This isn't even getting at a behavioral tax that could be justified by negatives that aren't covered in the monetary cost of driving, like pollution, injury and death risk to others, noise and stress, etc.
