Just wanted to throw this out there...
I'm my way to work my V1 picked up a radar signal, and I noticed it was increasing in strength. Soon it got to the point where I realized I was approaching it. LONGGGG before I even saw what it was, it clearly notified me that up ahead my speed was about to be taken. Turns out it was one of the speed reading signs that tells you your mph. That said, if it had been a cop that my V1 was picking up on, I would've definitely been in the clear because the V1 gave me a huggge heads up before hand. +1 for V1
