I was driving home today from work on the Dallas North Tollway and just when I got on the freeway I got a burst of 4 laser alerts in a row for about 15 sec each from behind. I was looking around and couln't see any LEOs behind me but I did notice a new black Navigator behind me the whole way. As I drove along with him behind me I was continously bombarded by laser alerts. He then moved into the slow lane and the alerts stopped. Im just wondering if it might have been his cruise control that was setting off my Laser alerts. Any ideas??? :? :? :?
