I have driven on the left hand side all of my life. The worst part of driving on the right for me is roundabouts with no marked lanes. I always hire an automatic car as I've driven one for more than 20 years. My daughter has a Peugeot and the wipers/ indicators are on the opposite side to what I'm used to. I can't tell you how many times I've wiped the windscreen when trying to indicate! As a pedestrian, it's so natural to look left first, I've come close to death several times when overseas. Great story!
