I suspect the economics may be changing too. 20 years ago, they
were in effect almost free to run in terms of power, as they
used the spare overnight capacity of our nuclear plant which
was otherwise wasted. This isn't true anymore and they do cost
a lot to run nowadays. As I often do motorway runs at 2am and
find the roads empty with thousands of lamps lighting my way
into the distance, I do wonder how long that may continue.

I feel the lighting level is often excessive, and a reduction to 25% of
current levels would hardly be noticed. I feel the transition between lit and
unlit sections should be extended by am area of in between levels, to enable
eyes (and speeds) to get adjusted to the new levels.

I notice they've reduced the lighting levels in some underpasses round
here with the result that, on a sunny day, you can't see a damned thing
until your eyes adjust
