I don't see people injured on the video, and only one who may be frightened. But what I do see is stupidity en masse, which tends to be funny.

That's not nearly long enough to learn how to drive in it.

Is it not taught when you get drivers' licence? What about public warnings? (Also, though I couldn't yet track down the origin of this video, Helen is right in that it appears to be a North American location where snow is more commonplace.)
