The Australian: Know-all parking meters for LA [September 23, 2005]
: "This ploy no longer works, because short-term parking spaces are equipped with GPS-enabled cameras that scan number plates and know how long a car has been in a particular spot, chalk or no chalk.
Pacific Grove, a coastal resort town, has taken parking meter innovation one step further. Its machines are programmed to increase parking fees over time, so that quick errands cost only a few cents, while longer stays can cost several dollars. A wire grid under the tarmac triggers a sensor when a car pulls in. The information is then beamed to traffic wardens, so they know when time runs out on any parking spot in town. The city is leasing 100 such meters for $US45,000 ($58,400) a year.
To help pay for the technology, the city has taken a rather more old-fashioned approach. It has told its traffic wardens to work on Saturday afternoons."
