I have just seen the video and that is just plain crazy!!!
Whenever I ply Jogoo/outerring road I see buses with more than 5 makangas, I normally treat them as suspects, woe unto you when they hit your car, the harassment you get will make you simply drive away. Any vehicle should only have one makanga.
