Finding a carpool has never been easier. MyCarPoolStation.com delivers a comprehensive search for car-poolers in your area, for work or school. The site offers security checks on drivers as well as a rating system for reliability.
Nothing is perfect but if you need to get out of the traffic and expensive city parking lots try car-pooling. You can also check their on-line calculator to see how much CO2 you are saving.
If still unsure ask around at you work and find people who live in your area. You might be surprised to find a neighbour who feels the same way about driving to work.
