The police ARE using instant on laser. I got hit last night twice. The first time he clocked me at 80 and pulled me over. I was able to talk my way out of it due to friend and family on the job, and it was rather late so I wasn't endangering other drivers. The second time was a few miles later but I was right around the speed limit. I'm going to looking into some laser diffuser units. There was a group buy for one on the bimmer boards that I heard worked really well. I'll post the info that I find.
