He got his rear end pushed in and his ego flattened at the same time
We roll into this footage somewhere in Mother Russia with our truck driver and his dash cam recording. He's stuck behind a big truck and you can hear a car honking like mad behind him to speed up, which he can't. We finally get to see the guy in his Audi when he pulls around our driver and then starts slamming on the brakes. After a couple of times he flips our driver the bird, who decides he's had enough and rear ends the Audi. When they both stop and get out the finger flipper quickly notices the size of the truck driver and retreats to his car before he gets his ass kicked.
Next time maybe he's keep his gestures to himself.
