Roadside radar is pass . Apparently, the hip new thing is Astucia's speed detection stud. Designed to be hidden in lane-markers and linked to roadside cameras, the speed stud uses infrared to assess the speed of a vehicle and then shoots it over to a roadside box. Of course, what's to stop somebody from going out late at night with a Makita cordless and drilling the things? Nothin', that's what. Cool Hand Luke will have his revenge.
