Carpool

Carpooling is a private agreement between several people to go regularly to a similar destination. A typical example would be that several workers from the same company who live in the same suburb take turns in driving to work.

The major challenge of carpooling actually is that there has to be a very strong geographic and time overlap. In my opinion, only a web service with a large local user community will be able to achieve success because poor results due to fewer users can de-motivate potential users very quickly.

It is quite surprising to me that Google India, having a very big user base through its social networking application - orkut; is not taking any initiative in this context.
