Fairly sure it's not the Abbey

As for driving on the left, I understand that from Roman times until Napoleon Bonaparte came on the scene and decided to change things, it was the norm to drive on the left, because the coachman normally sat on the right-hand side of the coach because more people are right-handed than left-handed and would hold their whip in their right hand, so it made sense to pass right ride to right side. So the left side is really the right side and all you folk who drive on the right side are on the wrong side
It's actually no big deal. I've driven both right-hand and left-hand manual drive cars and left-hand automatic cars in various parts of Europe and North America. Just think carefully when you drive off - say out loud 'drive on the left' as you start the car, and take extra care when turning right.
And whatever you do,
don't even think about considering to attempt to drive in Edinburgh. There are an awful lot of one-way streets and streets with one end closed off. It's very difficult to get moving, almost impossible to stop if you do get moving, and very expensive to park. There is an excellent bus service. Dump the car and use the buses.
