Moving from one country to another makes you wonder about ten thousand little things that are different, things that you never before thought about the reason. Case in point, how do people park their cars in your neck of the woods?
In my previous country, 99% of the people in big carparks will park nose forward, then reverse out. In this one, 99% reverse into the parking space, then drive out front first. In my mind the old way was "obviously" more sane, since reversing into a small space is difficult, while reversing into the wide open space is much easier.
People here get taught on their test to do it this way, they all continue to do it, and nobody could explain to me why. Until recently, when somebody told me a study had showed that reversing out of a parking space was much more prone to accidents then driving forward out of them.
Only one of ten thousand things, but this one I now understand, better then say, carpet in the bathroom :-)
