the max ci360 (and other similar types of radar detectors) blocks lidar (laser) gives the cop an error on the lidar gun. we did some testing with a cop here on the forum when he came by the shop. be couldnt get a reading on the speed of the car as it passed by. it has saved me quite a few timesYou can get false laser alerts from the Face ID on your iPhone triggering it. But I turn laser off anyway because if you are getting lasered (which is targeted) you are already getting a ticket. You won't get stray lasers alerts when a cop is targeting another car like you do with radar.
