Frances Pliskin had to stop driving over the summer. But Pliskin, 90, still needed to get to and from her weekly hairdresser appointments and bridge group, monthly dinner date at the Westin Club, and to visit with friends. "I have a balance problem and I use a walker, and my doctor felt it was in my best interest and the people on the road if I didn't drive," Pliskin, of Cherry Hill, said. "Obviously, that meant taking away my independence." Enter Uber. Or, in this case, S-Uber.
