interesting focus...maybe a play on environmental impact, incentives for carpooler

carpooling apps and social login not novel; thought postal code use was ok, challenge is chicken and egg - enough people using it to find partners. endorsement an added interest.

Carpool tool. Lacks time factor, no incentive for use
