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.

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.

A slight issue: the very latest TomToms don't, yet, have the facility
for uploading the database, but my Go 930 does. TomTom imagine their
decision to not incorporate the facility is an improvement but feedback
seems to be persuading them of the error of their ways.
