Given the nature of traffic in China the one angle they don't show in the video is the one that matters most... what happens when vehicles in front of the bus straddle the lane, blocking it? They line up neatly coming from the back because they physically have to but anyone who has seen the traffic in China knows that cars will not get out of the way or obey the lane markers and are quite likely to abruptly (even at risk to themselves or their vehicle) cut the thing off from the front in order to squeeze in front.
