Architecture screed Bldg Blog profiles Los Angeles's traffic control system, which uses an intensely complex system of cameras, embedded roadway sensors and control rooms straight off the set of "War Games." One of the coolest features are the loop-like sensors — literally, inductive loops — that detect the presence of cars (or other large metallic objects) and relay the information to the processing center in real time.

Think of all that technology eyeballing your ass next time you challenge the guy in the Supra to a stoplight run.
