You can't design a road for "no speed limit whatsoever". Britain's
motorways were generally designed for 70 mph, but it's obvious
that the first bend on the M4 going west was designed to a lower
standard. I thought the 50 mph limit on that stretch was imposed
from first opening, BICBW.

My understanding (based on dubious discussionswith policemen
friends of mine!) is that the motorway network in the uk is
disigned for safe travel within lanes upto 120mph.

I think you mean 120 kph.
