I think I got my first Audi false alert sometime in the last 3-4 weeks (radio, not laser, can't remember what band). Laser false alerts from other vehicles are fairly common. Infinitis, usually the SUV, will give me laser alerts from behind because of the adaptive cruise. Mostly GM, but a few other vehicles will give me laser from the front due to their LED third tail lights. Over the years, I have gotten a few false alerts in the radio spectrum due to various vehicles, and in at least a few cases, it was because of a radar detector in the other car.

IIRC, the Audi alert the other day was quite strong when the guy was behind me. It was a full strength alert for a while. Very irritating.

I've even gotten laser false alerts from neon signs once or twice when I pulled up very close to a store that had them and a handful of times from the sun being low in the sky shining through a wet windshield. I have to assume some of the water drops acted like a prism and triggered the correct wavelength or something.
