When I was eight my folks took the family through Custer State Park in South Dakota to see the Bison herd. We saw a guy pull his truck over by the side of the road, get out and walk up to a solitary bull to take a picture. My dad pulled over to the side of the road and told us "Watch this kids. This guy is about to die."
Fortunately for our young psyches when the bull charged the guy was able to jump through the window of his truck. The bison didn't slow down and rammed the side of his truck. That was back when trucks were still made of metal, but it left a huge dent.
