Guinea pig
There is heavy vehicle congestion from the large percentage of the population who chooses to drive. This results in a parking problem. Corporations have made various attempts to solve the city's parking problem as a Guinea pig location. There has been little success. Parking restrictions are strictly enforced, and the complicated parking hours posted on signs can be confusing. Environmentalists question the free parking spaces given to thousands of Congressional employees, discouraging them from using public transportation.
