If you are moving up through the traffic lanes and you see a white Volvo station wagon with a white M-B in front....(and a lot of traffic hanging back for no apparent reason) DON'T overtake them. You'll give the protective detail in the white Volvo a heart attack. It seems a certain elderly gentleman lives in fear of motorbikes going past his white M-B. You've been warned - this is something the locals know but I had to learn the hard way (well - not so hard, I'm still here to post about it). The reasons are apparent when you think about it.... the same reason there are NO motorbikes in Assad's Paradise Syria.
(Note - sometimes they use white Prado's as well which are very rare on the roads).
