There's a simpler way: ban SUVs and home trucks, or at least revoke the tax incentives for them and tax them like large cars, which they basically are. Want to have a truck? Prove that you are doing business with it that can't be served by a car, or pay lots of taxes. Want to have a home tank? Prove that you're an army.
