See the driver's facial expression in the opening snapshot (you can call it a dash-cam selfie too) taken from the 11 second mark in the video? That's the universally known and understood human expression for "oh shit, we're screwed now and there's nothing I can do about it".
Quite possibly filmed in Russia (there's no mention of the location in the posting), the driver of the car fitted with twin-dash cams, one facing the road and the other towards the passenger compartment, was confronted with a big moose jumping out of the forest and entering the asphalt.
We don't know what happened to the large animal, but the humans in the car reportedly made it out alive and well.
