Article in /The Guardian/ suggests these are already (optionally)

 But, it seems that these don't truly *limit* speed; rather, they
signal when the speed limit has been *exceeded*.
In my old(ish) 2015 Honda Jazz (Fit in USA), it does both. A camera detects the speed limit and shows it on the dash display. I can then choose to set the "limiter" - better called "speed detector" to that speed (+/- a few mph if I wish). When the car gets to that speed an alarm sounds and the car will not accelerate beyond that speed on the level or going uphill. It will happily continue increasing its speed well beyond the limit if going downhill, with the alarm beeping away!
It does *not* apply the brake automatically when entering a lower speed limit area when the "limiter" is set. That could be dangerous to anyone following closely behind.

And, can be disabled?
It's disabled by default when I start the car. It has to be turned on when I want it.

Do vehicles "tattle" on drivers that exceed the limit?  Or, is it
intended as a reminder (nag!) to help people drive more safely?
Well, supposedly the latter, but I wonder if it's stored in the cars memory somewhere and can be accessed when the car's serviced.
Note that on more modern cars it is often linked to the Satnav/GPS where speed limits are known by position rather than signage. Of course, if you don't keep your Satnav's database up-to-date that's another matter entirely. ;-)
