Can you tell what it is yet?

Not that much mate 'cos Joe has figured it out. I think it is a driving on the left hand side of the road thing - Sweden should never have changed over to the dark side!

Well, all of our cars were LHD so the change was more than just logical for us because it's a pain in the a.. to overtake someone when you're next to the side of the road.
I drove a RHD car here in Sweden for many years and it was near impossible to overtake on some roads!
