Some relevant facts: 1) Ridesharing has been around for decades. There were high-tech phone-based ridesharing programs in the 90s. I don't think anyone claims the idea of sharing rides itself is new. 2) There are many ridesharing services including us (http://www.ridejoy.com http://www.ridejoy.com), Zimride, and Carpooling.com, where drivers give passengers a ride to someplace the driver is already going. Lyft (a new offshoot of Zimride) and Sidecar have appropriated/redefined "rideshare" because it sounds friendlier and less commercial than "car service". Uber doesn't use the word rideshare. 3) Having used both Lyft and Sidecar extensively, the fact that it's a commercial transaction doesn't change the fact that the experience with either one is generally as good as, sometimes much better than, actual taxicabs in SF. It's also a bit cheaper and you're more likely to actually get one. Hopefully the state just requires adequate protections instead of killing these very useful services.
