Hence my Dragons Den suggestion of a sat nav that
actually tells you what the speed limit will be 400m ahead,
rather than less usefully what the speed limit is now.

It already exists.

Nope.

Stick the speed camera database from www.pocketgpsworld.com on your
TomTom (other satnavs are available) and you can set it to warn you,
at whatever distance you choose, of the actual limit at the camera.

Speed camera databases are useless for the latest approach of speed
cameras in small vans etc and for the cops on the road as well.

As usual, and as others have noted, you haven't a clue.

You never could bull**** your way out of a wet paper bag.
