Just when you thought the police had everything they could need to catch you speeding (radar, laser, VASCAR, photo) comes a revolutionary new concept that will change the way you drive forever.
The system, currently being tested by the University of Tennessee, determines your vehicle's speed by way of microphones (hidden on the side of the roads) which calculate speed by the sound of your car!
Yes, you heard right.
These devices filter all surrounding noise, leaving only the sound of your engine. Software then calculates the vehicle's speed by measuring the engine sound's Doppler shift - the change in a sound's pitch as its source moves past an observer.
The system can also measure the engine speed in rotations per minute by detecting the pulsing sound made by the pistons. You gotta love technology.
But there is one thing they haven't seemed to figure out... how to determine which car caused the high speed, so the device can then send information to an awaiting police officer down the road to pull over the suspect. However, something tells me they'll come up with a solution soon enough.
Right now, the device is in its initial stages of development. They've tested it by secretly hiding it in street signs along various roads in Tennessee. So far tests show the device is accurate within a few miles per hour.
No longer will you have peace of mind using your trusty radar detector. It will do absolutely nothing to warn you of this speed trap since the device emits no signal whatsoever.
We as motorists are going to have our hands full in the coming years, because this device is but one of several currently being developed to catch speeding drivers for the sole purpose of increasing revenue for the states. As if our tax dollars weren't enough!
