Russian drivers as a group have an odd fixation on dashcams. Maybe driving there is so wild that it’s necessary, maybe their version of insurance requires it? Don’t know, but there are an incredible number of Russian dashcam videos on YouTube, from private citizens.
I read its because of corrupt cops who charge them for infractions or accidents they weren’t even involved in, or were not at fault. And judges have been accepting the videos as evidence for the defense..
