Police of the future could be able to detect distracted driving with the same effort as spotting speeders by using radar guns.
A company in Virginia is developing a device that has the technology to determine if someone is texting and driving. The radar-gunlike device detects the telltale radio frequencies that are transmitted from a vehicle when someone inside is using a cellphone according to Malcolm McIntyre of ComSonics. It’s similar to a device that cable repairmen use to find leaking frequencies in a transmission.
