On the back of thriving pilots in the San Francisco Bay Area and across Israel, Google's Waze is bringing the Waze Carpool navigation app to life across California on June 6th.

For hose not familiar with Waze, it is all about contributing to the 'common good' out there on the road. By connecting drivers to one another, Waze helps people create local driving communities that work together to improve the quality of everyone's daily driving. That might mean helping them avoid the frustration of sitting in traffic, cluing them in to a police trap or shaving five minutes off of their regular commute by showing them new routes they never even knew about.

After typing in their destination address, users just drive with the app open on their phone to passively contribute traffic and other road data, but they can also take a more active role by sharing road reports on accidents, police traps, or any other hazards along the way, helping to give other users in the area a 'heads-up' about what's to come.

Riders who accompany drivers on their routes share their gasoline expense, calculated at no greater than the federal mileage rate of $.54 per mile.

Waze currently takes no cut of the transaction but will eventually take a commission when the quality of the service is high enough to warrant this, Waze said.

During a test pilot in Israel, where Waze was founded, the company took a 15 percent cut.
