I was thinking the other day how I've only once been hit with instant-on and I think it was from a cop coming the opposite way who happened to turn his unit on right then. For sure if it was my side of the highway I would of been toast. 70 (slowing down) in a 55 with barely any traffic.
Other than that it has either let me know ahead of time (one bar) before it shoots up to six (or is it five?) I always figure one or two means you are ok. Three is close and above that you are nailed.
Is that accurate, do you think?
