When the automobile first rolled onto dirt roads in the 19th century, it allowed us to go places we'd never been and let us get there in a matter of hours instead of days. Unlike the train, which confined people to stops and schedules, the car gave us an amazing sense of freedom. Today, our cars still give us great freedom -- but in many cities, that freedom is tempered by the annoyance of heavy traffic. There's nothing quite as frustrating as being late for work or an important event because of gridlock.
