I realize that I'm just throwing more anecdotes into the "NOT DATA" bucket here, but the last time I visited Russia I was driven around by my grandfather and uncle. It was probably one of the most terrifying things I've ever experienced on the road, and I've had a tire blow-out in a Ford king-everything truck, as well as losing power-everything in the same truck, both times going 70+ mph on a highway.
I never saw anyone trying to pull a scam, but my impressions - and this was about a decade ago - were of a Road Warrior type environment. The distinction between road and sidewalk was a mere suggestion, traffic signals were the equivalent of someone shushing you in a library, and lanes - what lanes?
It's not isolated, but it's not happening on everyday basis too.
Anecdotally speaking, I haven't witnessed things in their "The Russian Dash-Cam Supercut" video even once. I can confirm that lots of people disregard rules if they think they can get away with it, though. Things like not lowering speed before the yield sign or going full speed through the crossing on yellow traffic light account for majority of the accidents involving two cars. Crossing the road in the wrong place causes most pedestrian deaths.
Statistically speaking, we've got 3-5 times more fatalities than EU countries per capita and about 1.5-2 times more than in US, from what I've found. Some of these accidents happen due to weather and poor road maintenance, but you can't really blame the weather much, since the situation is much better in neighbor Finland.
