A few weeks ago a guy in a Santa Fe drove me completely nuts. It took me ~10min to pass this joker. I was driving at my regular high rate of speed when I got a K band alert on my V1 from the front. I slowed down and the strength was low and steady. I gradually sped up and it ramped up. Eventually (I was being cautious) it went full blast as I was passing a Hyundai. The arrows went to the side and then rear. I let him pass to verify and looked at the windshield. It was dark but he had an rd with green lights.
The K band was so strong that it was reporting a mile away. I pulled over to get in touch with nature and a few minutes later I got the K alert again as I was catch back up to the Hyundai.
I was amazed at the signal strength I was getting from this car. Could it have been an RMR "jammer" putting out its BS? I doubt a cobra could be that strong.
