Traffic in America can be frustrating. But it isn't frequently "stop and block the other guy so I can hit his car with a crowbar" frustrating. Welcome in Russia.
It appears that drivers are trying to make this narrow bit of road into a four lane highway. When they come to a truck parked on the side of the road, things get close and shoulders run.
One thing you can do is get out of the car and apologize to each other. The other thing you can do is block in one person, get out of the car, and then hit that car with a crowbar.
I know how I'd choose.
