Parkmerced is well away from any transit hubs, but the community has established a flat $5 UberPool rate with Uber to nearby BART and Muni stops. (However, it won't contribute more than that for any Uber rides.) Depending on how often you need to travel to San Francisco, that might cover a handful of trips into the city, including public transportation.

One of the largest single-owner neighborhoods in the US, Parkmerced is touting the effort as a way to "bridge people to car-free living," the developer told SFGate. "The long-term goal is to de-emphasize car use, bring Muni [a rail service] into the neighborhood and use 21st century solutions to transportation." However, it's also a cost-cutting measure, as Parkmerced plans to provide just one parking space per housing unit, half of what is normally set aside for such developments.

The experiment is a first for Uber, which says that "by literally picking up where public transportation drops off, Uber is helping give people the benefits of car ownership without the hassle or expense." The idea also fits into recent studies showing that car ownership can be reduced if ridesharing companies like Lyft and Uber can cover the "last mile" of your journey. "This is definitely cutting edge," says UC Davis transportation professor Dan Sperling.
