Stalkervision:
Whistler was working on a VG-2 countermeasure long before you first contemplated the idea. I should know: In 1991 I supplied the VG-2 to Whistler that they used for developing their anti-VG-2 technology.
Mine was the only privately owned VG-2 in the world at that time. And I wrote the first stories on the VG-2 to appear in U.S. auto enthusiast magazines, beginning in 1992.
For those reasons I can say with reasonable certainty that Whistler started working on the solution about a decade before you'd first heard the word "VG-2".
