So you're driving down U.S. 287, cruising 80 in a 70 mph zone through Rhome.

Your radar detector isn't making a beep -- it appears to be a ticket-free trip.

A few days later, however, a letter from Nestor Traffic Systems in Rhode Island arrives with pictures of you and your vehicle. There's also a speeding ticket tucked inside.

Such a scenario may soon be played out.

Rhome city officials are negotiating a contract with Nestor to use a scanning-lidar camera to monitor speeders on highways, city streets and in school zones. "Lidar" is short for "light detection and ranging."
