The M25, for example. Its capacity is highest when
traffic isn't moving, because the gap between vehicles is minimised.
Throughput is typically highest at a speed somewhere between 40 and
60mph.

Actually it's more like 15mph, although that's unacceptably low to set a
speed limit.

Oh give it time. I'm sure the "Speed X - 10 causes less 2 * less fatalities"
argument work its magic and we'll all soon be back to walking pace with a man
with a red flag in front. Once 20mph is everywhere we'll soon have the
campaigns for 10mph kicking off. But remember - Think Of The Children!

Not many pedestrians on the M25.
