Even if the vehicle itself were free, fuel, maintenance, insurance, taxes/registration, tolls, other taxes, and parking still end up being $1000's a year. $50k over the lifetime of a vehicle would probably be cheap. This seems to undersell the cost of a vehicle. Granted, some of that cost if paid by people who don't even own a vehicle. But there's also the indirect costs, such as increased cost of healthcare from more solitary and sedentary lifestyles, the cost of wars over fuel, etc.
