Hi all,

Nearly all London squares have a clockwise one-way
system, even though when all of the roads in and out
of the square are one-way, an anti-clockwise one-way
system is superior (because drivers have
better visibility when curving to the left).

I think that's a very marginal advantage, offset by the better
view of vehicles joining the roundabout from the driver's left.

Why would traffic already on the square need to have a view of traffic
joining it, over whom they have prority?

Many squares, such as St James, have roads
which are wide enough to be two-way,
and the squares are large enough that you don't
particularly want to be forced to go the long way around
for no reason, so I don't know why they one-way at all.

The road around St James's Square is not all that wide,
but it does allow a slow car, whose driver is seeking
a parking space, to be overtaken.

I can't think of any non-square which has been made one-way just to aid
overtaking of parking cars.
