Turn Signal Light Show

Have you ever been stuck at one of those huge intersections where a major artery crosses a highway? As a result, there's traffic banked up on the other side waiting for a couple of minutes to turn.

In the future, as a government initiative to reduce road rage caused by waiting for upwards of ten minutes at a set of lights, it is imperative that new wireless technology be produced to network turn signals. Their actions can then be synchronised and produce amusing patterns for surly motorists.

Some traffic light sets communicate using radio signals. Why not utilise this? For example, a car can roll up to a set of lights and then establish a link with the lights which will eventually perform a coordinating function. GPS systems can judge the path of the car and then each car quickly loads a script (depending on what direction it is going in,) and participate in the turn signal display. Fun abounds.

As an addition to this, extra information can be loaded to the coordinating traffic lights like the radio station being listened to. If more than 90% of oncoming traffic queued is listening to the same station, the lights can then tune in, listen, and make another amusing pattern based on the beat, and tone of the music.
