With traffic control in Moscow left in the occasionally sober hands of its citizenry, a group of young protestors has taken up the task of teaching manners to motorists — even if it means getting thrown on an SUV's hood.

The group StopHAM has been battling drivers who roll on sidewalks as part of a broader campaign for several months now, but the new video shows just how aggressive their tactics — and the response from drivers — have become. Given previous videos, the activists seem to think that by using women, video cameras and non-damaging liquids, they can shame drivers into changing course without getting its members injured.

Because in Russia, randomly confronting people about their bad parking and traffic habits will lead to some impolite conversations, the occasional flashed pistol, and words with gentlemen in blacked-out Mercedes SUVs who are not accustomed to being disturbed.
