Why would I say goodbye to my pickup which has a 5.7 liter engine? I can afford the price of gasoline even if a large tax were to be added. Please do not assume that everyone is willing to suffer driving an underpowered, small size automobile to save a few bucks (or to appease a few overzealous environmentalists). Charging by the mile is the only fair way to tax.
