The car filmed does seem to have European plates, so the person filming could be the passenger of a right hand drive car. But I can't really tell much more from the video
It less serious than this but on my drive home there is this spot with 4 car lengths between stop lights and people with trailers keep taking it as free right to get into the middle of 3 northbound lanes blocking off the far right lane for turning right at the next light
