@DavidPostill Not sure if that was setup for a further pun, afraid I've got nothing!
Though AIUI they considered changing the signs over at some point?
but was deemed to be too costly or somesuch

maybe it was the estimated cost for switching driving side to the right
which is better because something something Napoleon hated the British?
or because he was left handed
or another reason entirely
