It's always
intrigued me that America chose to drive on the right, given the large
number of British people who settled there. No doubt the number of
immigrants from other European countries swayed the argument.

This web-page has some interesting ideas on the reasons behind
left/right driving, taken mostly from the book: 'The Rule of the Road:
An International Guide to History and Practice' by Peter Kincaid .

Sounds a fascinating read at $50, but unfortunately currently out of stock.
