At first, when you look at this picture you really think this guy is actually levitating, when in fact he stays next to a wet spot on the pavement. Really clever idea and a good angle for the photographer.
Even tough it's king of dangerous, and illegal too, I think that guy had a lot of fun skiing downtown Bucharest dragged by a car. The good thing for him is that it was plenty of snow and there were not so many cars, so he could sky free of any danger.
