That's kind of a rude response to someone relating a personal experience. Yes, I have personally experienced Russian drivers getting offended when I try to put on a seatbelt. Maybe it's changed from when I was there last 4 years ago as it's entirely possible that they've begun cracking down on it, but this was certainly the culture not very long ago (like much of the rest of the world). I'll also note that most of my time in cars was not in Moscow or St. Petersburg. This 2010 study suggests seatbelt use is rare in parts of Russia: http://www.ncbi.nlm.nih.gov/pubmed/22414131
And here are similar experiences to mine: http://www.passportmagazine.ru/article/786/ http://www.pistonheads.com/gassing/topic.asp?h=0&f=23...?
