enforcement. Apparently also not in UK ere now. And when ~everyone exceeds arbitrary speed limits, the numbers are deemed low by a vast majority (if the reporter gives an accurate view of that situation) - then there will be civil disobedience. As here - remember '55' ? Those who study driver behavior - repeatedly refer to the RMS speed being an intelligent practical guide to a road's safe 'capacity'. Such stats 'mean' more than flat numbers from initial engineering guesstimates. Your example is rare in my lore - raising a rate VS more fines... but nice.
The cameras are already demonstrating where they are leading: as far as the Authority can manage. UK is just a bit ahead of the Tampa experiment in moving to the long-term data collecting stage. I am so glad that you are happy with the arbitrariness of "49 MPH is Peachy: 51 MPH is $150" - especially when of course, revenue raising has *nothing at all* to do with this enforcement for our comfort and safety. And I guess you'd see nothing wrong with timing you over a 10 mile span - for that 1 mph, that all-important number?
Exact speed is an easy thing to measure - but has little to do with competent driving. So we decide to make it so arbitrary as +/- 1 mph = innocent/guilty (of something?) no matter What the conditions. For convenience of Authority and $-collection, not for sane enforcement of sensible driving. And we all know this.
We ever opt for the simplistic solution and apparently - many will accept the 'speed tax', rather than raise $ another way - as, empowering police to exercise prof. judgment and tag the really dangerous drivers, whose actions often have little to do with vehicle speed - just ego and dumbth. Fairer would be more expensive. What's 'fairer' worth?
Meanwhile we shall each continue weighing the odds as we see them. (100% compliance with arbitrary laws would measure both a Puritan and a post-mortem society. We haven't died fully, yet)
