Both Lyft and Uber have also been testing a form of carpooling, but both just allow riders on the same route to split the cost of a regular fare. By contrast, Waze's service sounds more like UK's Carpooling.com, letting fellow drivers share the exact cost of a ride and no more. Waze didn't give any other details like what kind of fee (if any) it's collecting, and just said it's "conducting a small private test in the greater Tel Aviv area." It added that it might be hard to find a ride in Tel Aviv at first, but that the problem should ease as new drivers sign on. Google acquired Waze some two years ago for an estimated $1 billion.
