I'd never give up my automobile. Anyone who would in my opinion doesn't understand freedom. You can't be free if you aren't able to go where you want, when you want without the government regulating your every move.
Public transport, cycling, walking etc. are all strenuous exercises easily controlled by an autocratic big government. To maintain the rights of citizens and to stop government oppression we must defend our motor cars at all costs.
Smaller government, less taxes, cheaper fuel, more houses! Live how you want to live.
