I disagree with you about the web forum I recommended. Who are you anyway? Every one of your posts concerns the K40.

 

I might be missing something here, so please correct me if I'm wrong... In Canada I have never seen laser enforcement from the rear. I usually drive about 20kph above the limit, so anything closing from behind is a concern for me, but if it is a cop, he doesn't need radar because he can just clock me so all of these systems with rear sensors leave me scratching my head. I won't even go into radar from the side ?!?! What good would that do - I could be going 100 mph and the cop would read 30, so as I see it, the only real value are the front sensors - paying for 360 coverage is just a waste of time/effort/money. ... Sorry - my 2 cents.
