I agree with GreenVanMan.
Before lockdown I was driving some 800-1200 miles a week, for the past 10 years, mainly commuting but then for family stuff on weekends also, usually covering areas on a weekly basis I'd never seen.
Sticking to the posted speed limits has been the sole reason for no tickets! Yes its annoying seeing 20mph speed restrictions on the M6 at 3am with nothing in sight
Having every retard tailgate and flash you around the M25 for sticking to the posted limits boiling my blood for hours
etc but, my motto is don't speed and you have no fear of getting caught out!
Many a driver who may have been stuck behind me doing 30mph in a 30mph should be grateful as often they would have got caught by a scamera van further up, only getting off my bumper when we go past one.
