Hey drone351, that sounds like you've been dealt a harsh blow. Speed infringements at such low speeds just don't make any sense. At low speeds, the ability to hold a set speed is much harder. I heard a while back, and its probably not true, but the 'cut off' for a ticket being issued is 110% of the speed. This is fine in a 60 zone (66 cut off) but when you get down to speed limits of 25 km/hr or 50 km/hr the gap between the speed limit and a ticket is ~5 km/hr. Well its a theory anyway....
And I agree, dron351, I'm so paranoid about not going over the speed limit I probably spend 10 seconds out of every minute in the car checking out the speedo!
