I agree that all forms of motorized transport are heavily subsidized. We're already subsidizing the highways, gas, lack of pricing of externalities such as air pollution, etc. Given all that, why should taxpayers further subsidize the vehicle itself and the operator, instead of letting Google pay for all of that?
