I am left-handed. As a result, I grew up watching righties doing things and being a little garbled in my orientation because of it: to this day, I sometimes have to make the "L" with my hand to remember what is left and what is right.
The relevance of this to today's post is that I have very little confidence in my ability to drive on the opposite side of the road. Even as a pedestrian in Britain I usually look all of the ways before I attempt to cross a street. Although I've been there many times, I've never driven there and have no intention of doing so. That leaves public transportation as my primary method of getting around, and it's actually one I've come to prefer.
