Leadfoots, beware: Chicago recently installed 50 more speed cameras around town. And you barely have to exceed the limit to get nailed.

Baltimore Washington New York Chicago
42 mph ($40) 41 mph ($92) 40 mph ($50) 36 mph ($35)

Here's more info about the program, and a handy map showing where the new cameras are being installed.
