Ed Rush asks,
Now for the question: does anyone here know how it came to be
that the Brits and others drive on the left side of the road and
the Americans and others drive on the right? I must assume that
16th-Century (or earlier) carriages had a similar protocol when
passing on the road.
I believe it comes from the days of horses when you always wanted to
have someone pass by on your right side so you could watch his weapon
arm, as you never knew who was friendly and who was an enemy.
