Wouldn't it just be easier to drive the speed limit

I resolved more than ten years ago to drive within the speed limit and religiously try to do so.
However, along with the overpopulation of speed cameras, it seems to me, comes the overpopulation of irrational and overbearing speed restrictions: The road from Leeds to Wetherby goes 30, 40, 50, back to 30 etc., so many times that it is difficult to remember what restriction you are currently in. This can only be designed as a method for police revenue collection, as it's only other purpose is to increase frustration rather than to increase safety.
For this reason, I sympathise with anyone who feels the need to decrease their vulnerability against running up points.
