I'm really excited about SFPark. It's mentioned briefly in the article, but the idea is this: parking meters that can sense when a car is present and dynamically set its rate. The meters will be set so that parking is (almost) always available anywhere in the city -- at a price. This will include parking garages and other pay-to-park places. If they do it right it will remove all the guesswork out of determining where to park. Should I go for that garage, or drive around the block five more time? I could have an iPhone app that can show me the cheapest parking spot within 2 blocks. This solves the problem someone else here brought up, which is that people prefer to shop where parking is free. In this model parking is only expensive where the demand is high to begin with!
