Rental businesses let San Francisco drivers share their own cars

SAN FRANCISCO – Shannon Stairhime and her car split up every morning. She commutes on public transportation to her job in the East Bay while her Toyota Corolla waits on the street for its next driver. “It used to just sit there and occasionally get tickets,” said Stairhime, who rents her car to neighbors for $5 an hour through a new business called RelayRides. “Now I feel like I’m contributing and giving back to the neighborhood.”
