A new GPS device has been launched that will allow drivers to warn each other about mobile speed traps and is apparently legal because of a loophole in the law.
The Mini Coyote requires drivers to press a button on a small dashboard-mounted box whenever they pass a speed trap.
This pinpoints the location and reports it to a central computer, which then alerts other drivers using the system. It’s a modern version of flashing your lights to warn oncoming motorists of a speed trap.
The Mini Coyote will cost around £199 and is available through internet retailers.
More than 50,000 drivers in France already use the device, which has been developed by GPS experts Coyote Systems. In September alone they reported 27,000 mobile speed trap locations.
The system is so efficient that a car travelling just a few hundred yards behind a driver who presses the button will be alerted to the danger.
If a driver constantly presses the alert at locations where there are no other reports of a speed trap, his transmissions are blocked.
