Just remember cops are stupid and they look for things that don't fit neatly into their box of preconceived notions of the way things should be. Anything outside the box draw their attention, you don't want to draw their attention.
Any one owning a vehicle means you have money, there for you are an automatic target as a source of revenue.
So when driving a vehicle you doubly do not want their attention.
Just think of how many people have been saved or helped by the police versus how many people are minding their own business abiding by the law the best they can and get screwed over by the police (like you).

Isn't Canada in the tank for man made globull warming?
You might be able to play that card in court and get off.

And get a radar detector (not a jammer). I know tons of people who have gotten speeding tickets. I know some people with radar detectors and they have gotten neither speeding tickets or tickets for having a radar detector.
Not legal where you are? Who cares. What the police are doing should be illegal. Chances are the cop is setting in a speed trap to "get" people who are from out of town, they usually hide some where that you are not likely to notice the posted speed limit change. Do you really think you should have to pay the state and the insurance company more for momentary oversight?
If they really didn't want people to speed then they should put up signs with flashing LEDs like they do at dangerous intersections. Or put up speed cameras. They don't want you to die in a dangerous intersection because that's too much paper work for them.
They would rather be working from their favorite speed trap handing out tickets.
