Traffic lights suck.
These could be a good thing. I see the potential of traffic lights becoming smarter, more aware, and reactive to the current traffic conditions. Imagine if EVERYONE had one and a traffic signal could tell when to change lights more appropriately. For example, we have a lot of traffic during the day, so our stoplights 'rotation' is set to a long delay. During the night, it's empty, but the stoplights still act as if it had to allow hundreds of cars through, meaning i'm stuck at a red light for 3 minutes while there's no traffic going through the green lights.
