In San Francisco, there is a competing service called City Car Share. There was also FlexCar, which Zipcar absorbed. I was initially a member of City Car Share because they had better prices. Also, they kept giving me bonus deals for cheap day long car rentals. I ultimately switched because Zipcar had far more locations and better cars. As a counterpoint to this article, when I lived in San Francisco I had an amazing experience with Zipcar. Cars were always available and there were locations everywhere. There were cool cars like BMWs and useful vehicles like trucks. Once I ran out of gas on the 101 and Zipcar sent someone out to help, no questioned asked. The guy on the phone acted like it was Zipcar's fault that I forgot to fill the tank! I've been less pleased with Zipcar in NYC because there aren't enough cars near where I live. However, there is so much public transportation, I've not had as much of a need.
