Here's a brilliant idea: A photoblog dedicated to showing motorists who park where they shouldn't. For instance, putting a large vehicle in a compact space. Or a vehicle of any size in two spaces. Start such a blog in your town!
Motorists are outraged about new "smart" parking meters that zero out any remaining time when a car pulls out of a spot. But I'm delighted! If such practice reduces the current practice of driving around to look for a meter with remaining time, think of the gasoline saved and air pollution reduction!
