Which things? The entire radar/laser systems? Or just laser detectors?I think those things are useless. They get you when they want to. I m not so sure of all the new technology but can't they just catch you with laser no matter what? What good is it going off after the cop got the laser on you already? The only thing I used in my truck that really saved me from getting tickets was a CB. May be I just live in the wrong area, with so much traffic due to population and so many cops.
