I’m assuming drugs were involved - I’ve seen this kind of behavior before.
Yeah, that’s what I didn’t get. If someone were trying to smash my window in, I’d be driving away rather than placidly filming it. It made me wonder if they were stopped for a reason - e.g. maybe there’d already been something that happened when they were both driving (a minor collision), and that was why he was raging, and why they were reluctant to drive away (because, perhaps, they saw him as less dangerous now that he was on foot, and not behind the wheel of a metal death machine).
