The abundance of the United States' freeway systems has led to the rise in single occupant vehicles thus creating major problems. Freeways promote sprawl developments, increase pollution and contribute a level of pride among society that estimates one class of citizen's superior to another. Yet, government's policies including the continued subsidization of fuel and transportation infrastructure supports the lifestyle of citizens that contributes to negative outcomes. Billions of dollars every year ensures that citizens continue to enjoy the auto dependency to which they have long since grown accustomed. If this policy direction continues, pollution mitigation measures and congestion elimination goals will force government to enact policy to revert these negative impacts in society. Citizens will be located in sprawled developments with no reasonable alternative to travel. This paper explores the cost that government pays for fuel and transportation infrastructure subsidy and calculates the true cost of travel per individual user. It evaluates single occupant vehicle owners' behavior and driving habits and analyzes their travel decision making process based on the subsidized transportation cost.
