"People who want to buy
"People who want to buy massive cars should pay for the privilege in the form of increased and more broadly/evenly applied gas-guzzler taxes, and road-use taxes based on vehicle mass".
We all pay taxes for the gas we use. We all pay the same tolls. Sounds pretty evenly applied to me. Why should additional taxes be used to punish someone for wanting to drive a larger vehicle over a smaller one?
