Driving down the freeway tonight I encounted a motorcyle officer traveling with the flow of traffic, with Ka constant on. I was about 1/4 mile behind him and the signal strength varied from 2-6 leds. Finally after following him for about 8 miles (and approximately) 10 minutes, the V1 had had enough and J'd him out. Shortly after that he pulled over a trucker.
It the V1's defense, I did have plenty of warning when the threat first appeared. The fact that it J'd out after 8 minutes wouldn't have affected my ability to slow when the leo first entered the road way. So I don't really consider this problem.
