for those who cannot figure out simple patterns of traffic flow/speed enfcmt on one's usual driving routes.

There's alot of truth to this statement.

I have a V1 on all the time on my USUAL routes and it NEVER goes off. I'm doing various speeds (50, 70, 90, 100mph) and have never been nailed.

There are alot of other tactics you have to use as well as local knowledge. detectors give information that is merely PART of the whole picture.

Still I won't drive without one. I gotta get laser jammer now.
