Parking Spots

Here's a magnificent example of how technology might make our lives better.  San Francisco is, according to today's New York Times, installing a system of sensors on 6,000 of its 24,000 on-street public parking spots that will allow those with smartphones to get signals on which parking spots are open.  Wow!  If the system can also tell you how many other smartphone users are hurrying to get to the unoccupied spots, that would allow you to compute the odds of actually getting a spot.  Think of this same technology applied to open seating at a concert, lanes in a swimming pool, books in a bookstore, and more.
