This happened in Russia, which is like the Florida of Europe these days. It's scary at first, but once you see the cows stand up like they meant to that then there is a little relief. Is it bad that's the first thing I thought of and not the driver?
When I lived in Richmond, VA in the mid-90's there was a similar accident on Interstate 95. A truck full of Cows had rolled over after striking another truck which then burst into flames. At the time I was working at a local radio station and reports were coming in from drivers and police that flaming cows were running wild on the highway. So, naturally I went on the air and said, "We need to get a tanker truck of A1 Sauce to the scene immediately." My boss was not amused. I think he was a Vegetarian. Luckily, these cows were not set ablaze. Just tenderized.
