In January, OnStar announced an API would allow third party developers to integrate their applications with OnStar's platform. Last week, General Motors announced its first partner for API integration: RelayRides. RelayRides is "[t]he world's largest peer to peer carsharing marketplace." The partnership with GM allows OnStar users to leave their keys in their cars when renting a car to a fellow RelayRider. The renter can then unlock the car with a smartphone app or by responding to a text message.
Bike sharing, a common form of collective transportation outside the US, has started gaining traction in the US. A recent addition to the bike sharing scene, viaCycle, approaches the market differently than its competitors and hopes that its innovative approach will make it the Zipcar of bike sharing. viaCycle differentiates itself by combining the community aspect of bike sharing with "cutting edge IT." Within the IT competitive advantage lies the viaCycle API available for third-party app development.
