Good question...
I suspect it will come in, eventually. Cruise-control will have that effect but only if you engage it within the speed-limit!
My "sat-nav", a TomTom unit, displays my speed and the speed-limit for the road I am on, excepting for temporary restrictions presumably; and the indication changes to red if I stray over the limit.
I think heavy goods vehicles already have speed-limiters.
