I'm not sure if it's new, but GT police are definitely using Lidar.
I got hit this afternoon for the second time in the same location. Both incidents occurred around 1:45 PM on Tech Parkway, behind the big GT athletic building. He was shooting traffic coming from Northside drive.
I was lucky today. I was at about 55 on Northside, but remembering my previous encounter, I hit the breaks pretty hard as I came around the corner. Sure enough my V1 went off before I even saw him, right after my foot went on the break. He then kept the gun on me till I passed him, oddly enough, in a manner that kept my very highly mounted V1 alerting.
I'm not sure if they're actually making stops though, last week the same guy just flashed his lights at a range rover that passed me going 50+ (PSL+20).
