There's nothing more convenient than having your own set of wheels but sometimes public transportation is really the only way to go. It's cheaper and in some instances faster but it's also prone to a lot of delays. Have friends in San Francisco?
Today HopStop is pushing out an update to its iPhone app called HopStop Live! that now includes real-time user feedback in seven countries across 20,000 public transit lines. Users can now submit info on over 750,000 stops letting fellow passengers know just how crappy their morning or afternoon commute will be. Real-time info is available for every and any line or route that HopStop currently supports.
HopStop says there are over two million monthly active users, so the feedback should actually be useful. Of course, if your line is underground and without cell service, I'm not so sure you'll really be getting said feedback in real-time. HopStop says it will release updates to its iPad and Android apps in the near-ish future. [iTunes]
