That's its own separate issue, don't you think? The gas tax should be raised since it's a progressive way to penalize those who waste it and damage the environment as well as fund the roads in proportion to the damage they cause to them (since larger vehicles that cause more damage also use more gas)

This is an easy tax to avoid if you commute from out of state each day. (In fact, it's a hard tax not to avoid given the scarcity of gas stations in Manhattan)
