“ It is customary for Koreans to display their phone number in the bottom corner of their windscreen.” That’s a wtf cultural thing I didn’t know about Koreans
Also common in China. You can even get printed cards with a space for the number. Probably a healthier attitude to engage first and get angry second then a furiously passive aggressive social media rant or damaging the car, both of which I might expect if I blocked someone in over here.
It's because there's a huge shortage of parking spots and too many cars in Korea, particularly in big cities. It's customary to just park illegally and rely on the other party calling you if you're blocking them in.
Amazing that this is so common people would affix their number on the car at all times instead of maybe putting a note on the wiper the few times they have to screw someone double parking
If you drive in a big city in Korea, blocking someone in can be a multiple times a day kind of thing.
