Those Russian dashcams are fascinating in a horrible way. Soon after the fall of Communism my agent in Hungary jacked in her old Lada and got a modern fast Mitsubishi. Her driving was absolutely terrifying and she had three crashes that I know of, all caused by her own inattention. In the last one she caused a huge pileup in the middle of Budapest involving several cars and a bus, nothing different from what you see in the Russian videos. I reckon drivers in former communist countries are either drunk, drugged, on the phone, asleep or just not used to the speeds.
