Case studies of employers in Washington, DC and Los Angeles found that about one-fourth of employees began driving alone to work once employers offered free parking. Subsidies help these commuters choose to drive despite notorious traffic delays. In fact, the availability of free or cheap parking is one of the biggest determinants of whether a person drives to his or her destination, or takes transit, walks, bicycles or carpools. When employee parking is cheap or free, and most workers are expected to arrive at work all at once, drivers experience gridlock. This peak period traffic, in turn, causes government to try to solve congestion with more pavement.
Road construction costs tax -payers a fortune and cause delays that waste years of motorists time.
