As a Swede it amazes me that some countries allow parking "in the wrong direction". I've never even thought about it, and I don't know if it's a written rule (I'm sure it is, just it;s been a long time since I got my license).
Sometimes things just get weird.
I believe many Norwegians have received parking tickets when visiting Sweden because if this difference. I wasn't aware of this myself until recently.
I did it the other day and it felt illegal.
