you don't need to keep looking at the speedo, but can actually watch
out for more hazards than just speed cameras.

I agree and that is what I also use it for, but most with cruise fitted,
will not use it for that purpose, in fact that sort of use is not
advised.


Why is that not advised? I suppose that since cruise control only works on
the throttle - and not on the brakes - there is some risk of exceeding the
set speed on a steep decline.

most of my experience with cruise is in the US with autos, and there the
cruise slows you down using engine braking when the car goes downhill
