Your Own Personal Traffic-Light Changer
Eliminating red lights along the routes of their vehicles can give emergency response teams the few extra critical minutes that can save lives and property. Originally intended only for emergency vehicles, the $300 MIRT (mobile infrared transmitter) knock-offs available on the Internet emit an infrared beam that signals traffic signals to turn green and gives the vehicle the right-of-way. It is only a matter of time before self-centered drivers start using the devices widely to skirt traffic congestion, which is creating fears that chaos will ensue.
