I don't know about Moscow, but it's bad all over the UK
I think a lot is down to the almost total lack of non camera based enforcement.
The latest thing I see regularly (which almost stopped for a good 20 years or so) are people now, not just 'Amber Gambling' at lights, but going over, even 2, 3, 4 seconds after red.
Perhaps the 'I'll drive everywhere at 40 mph no matter what' brigade
30 mph zone - 40 mph, 70 dual carriageway - 40 mph in the overtaking lane..
Another oldie but goodie is people parking or abandoning their cars, anywhere possible.
Double yellows - check, on a junction -check, obstructing the footpath - check, parking on a narrow road directly opposite another parked car, blocking the road to anything wider than a car - check.
and on and on and on.
Cause? God knows, probably that marvelous since the start of the century attitude of 'I'm ok, fark you Jack'
Reinforced by almost zero policing.
We don't need to go as far as Russia to see bad driving
