It has long been reported that Google-owned Waze has been working on a ride-sharing service of its own. In fact, Waze Carpool has already been in use in Waze's home town of Israel. In the US, it's started off with a limited testing phase in San Francisco. Waze head of development Josh Fried revealed that Carpool is now actually operating in 9 counties inside San Francisco. But despite the still limited expansion, Waze has no delusions that it will be taking on ride-hailing giants like Lyft and Uber.
