When I am in France, this photo looks odd, but as soon as I arrive in Australia driving on the left hand side of the road is instictive. I have never looked at a photo of French roads while in Australia, but driving on the right ihn France is also instinctive. I've never had a problem driving in the UK in a French car, either.
Whether I could drive on the right in a UK car I don't know. I've never tried.
