An odd concept unique to the Northern Virginia area that goes completely against common sense, never get in the car of a stranger!!! Yet, hardworking folks in Fairfax County do it all the time. There are designated areas, which allow commuters to park, and hop in the car of a fellow commuter and head into town via the HOV lanes. The drivers head to the Pentagon, DC, and Crystal City. The pick up points are organized more by word of mouth than by a transportation jurisdiction. This is a very effective form of mass transit and cuts down on the amount of cars on Northern Virginia highways.
