They have them in the UK as well: on the M25 for example in the Heathrow 
area. But they really do vary here - they aren't just on/off but set the 
speed dynamically to try to improve traffic flow.

There are also indicator sings on all UK motorways which can be used to 
display a variety of signs dynamically, including variable speed limits, 
in case of emergency. Often they will graduate downwards from some miles 
away from an incident to slow or stop traffic. As far as I can see I'm 
the only one who takes a blind bit of notice of these speed limits and 
people get annoyed with me when I do! Funny world.
