I wonder if this will make parking better or worse. If everyone knows about open parking spaces, then everyone will rush to the nearest space causing more congestion around it. Once they get to the space and realize someone else got lucky, they will all go to the next nearest open space. So are you really solving the parking congestion problem?

As the article notes, the goal is to price so that 15% of the spots are always open. So it's not really about finding one rare spot -- despite the fact that makes a nice 'gee whiz' vivid opening story. It's about changing the entire calculation about street parking vs. off-street parking or alternate transportation.
