We were getting numerous (and I mean on the order of at least one every 30 minutes) of false positives which I believe were coming from big rigs. That is, while in the A mode, the V1 would alarm, first with a weak signal and then becoming stronger and we would slow down only to almost never see a LEO, but always seeing at least one big rig. In many cases as we passed the big rig going in the opposite direction, we would get a weak side alert and then a weak alert to the rear.. I also experienced a few times where I was getting a weak signal to the front as I was to pass a big rig and when I passed him, the V1 would indicate sideways and then fully alert to the rear right at the big rig. We had several of us in our group and we all experienced the same phenomena. It was almost like LE has placed radar emitters on the big rigs to provide us a plethora of alerts. Has anyone else seen anything like this from the V1s? It almost made the V1 worthless (though it did save our bacon a couple of times).
I just returned from Monterey, CA as well on those same roads and noticed the same things.

I suspect it is radar jammers and adaptive cruise control. Many of the new high end cars are using the radar front and rear for their cruise control.

The big rigs will emit a single alert as you approach from behind and got to a dual alert once you roll past them. It is so bad the V1 is just an annoyance. I only had two occasions when it alerted me to a real threat in almost 5,000 miles of driving. I had several hundred false alerts.

Some of the cars must be blasting radar at high levels. The Mercedes S class are using a lower level of power so they don't alert for a mile like some cars. Radar detectors are almost useless now and it will only get worse and worse.
