Early tonight I got a blip of 35.5 ka band, and as I was creasting the hill (which was a small hill) I looked aheat and saw a pair of headlights on the opposite site wating for the light to turn green. As it did I saw the leo comming towards me. I looked at my odmeater it was only .12 miles of constant on. I taught that this was very short. Because there wasnt no traffic or curves, just 2 small hills. Could it be because of those hills it was a really short warning. Even thought my v1 is as high as It could be.
