When I was in Saudi by in the early 90's the roads were slick. Months of super hot weather with no rain, combined with cars that did not have the best emissions standards made for slick residue build up. This video shows the normal surface, but watch out if it rains. The oil build up makes for a crazy slick surface, at least for the first few minutes of the rain.
Oh yeah, I advise you turn down the sound so as to not get annoying wind noises.
