Where (and how) do you draw the line with gas mileage, materials used, and weight of the vehicle? If trucks are so bad, what are your opinions of popular SUVs like the Subaru Outback?

[misiti3780]

There should be a regressive tax rate tied to gas mileage, with exceptions for people/companies that can prove they need to use the vehicles.

There is - as gas is taxed per gallon, the drivers of less-efficient vehicles pay more in tax per mile.

[mountainethos]

Yes, but how do you go about deciding which vehicles are OK to drive?

[misiti3780]

Except it doesnt take into account if you need the vehicle or not.
