Right hand drive. Probably Great Britain.
That said, did Mr. Slapper make the situation safer or more dangerous?
The idiot jackass who slapped the driver just made the situation MORE dangerous, because now the passenger with camera is riding alone without a chance for the driver to jump back in and control the car in case of emergency. Sure, the passenger can slide over, but he can’t see much watching his camera.
The slapper was a moron. He made the situation more dangerous. These stunts are stupid and pointless and risky. You don’t make it worse by putting the driver down.
Jackass. Moron. Idiot.
Beyond that, it is assault. He had no right to touch someone else. He is a criminal.
Not UK.
No steering wheel on right side. Plates on vehicle in background are US. Man who whacked doofus yells at driver holding camera.
