Just FYI, the advice some police agencies and lawyers give for what to do when being pulled over is “place your hands on the wheel in plain sight and do NOT roll down the window or do anything else unless specifically instructed.” This is because of people that roll down the window ahead of time and then shoot the officer as they approach, through the lowered window but before the officer can see what’s going on in the cabin. This may be what he was doing.
Having had the opportunity to drive extensively throughout Euorope, one thing I’ve noticed in drivers there have much better training with respect to what to do when pulled over by police; pull over as soon as it’s safe to do so, then immediately turn off the car. Everyone understands this and everyone does this. Failing to do this is likely to result in a license suspension.
In most countries, the police will stay in their car and issue directions to the driver through the police loud-speaker. It’s very common to tell the driver to exit the vehicle and stand either by the ‘boot’ or the ‘bonnet’ then the police will exit their vehicle and make their approach.
All things considered, this is probably the better procedure. I’m not sure why law enforcement in this country doesn’t adopt a national standard. A better, universally understood SOP for traffic stops would go a long way towards ending much of the drama, IMO.
What you describe is reasonable. But after watching the whole video, it doesn't seem to describe this guy's behavior or attitude. He didn't roll down his window to put his hands out when they asked him to. Overall, every single thing he did, and the way he did it, seemed to scream "jerk" and "sneak." Those aren't crimes, but they sure create a dangerous atmosphere for both sides.
Seriously, if, as some said, the guy couldn't get out as they finally told him to do (because he'd stalled them on everything else), and his seat-belt would keep him from getting out, he could have told them that.
