e.g. US Virgin Islands.
Drive on the left with left hand cars (wheel closest to the shoulder). Now that's a seat biter!
That is exactly what Sweden had: Cars with the steering wheel on the left, which made the switch to right-hand traffic easier. Don’t ask me why this was so. Maybe the need to overtake others weren’t as great in Sweden with its low population density as it was in England?
Anyway, it was a huge change with all the roads that had to be rebuilt and re-marked, traffic signs moved etc, etc all over the country.
