I'll bet trying to avoid hitting various animals in the road is a major cause of wrecks, etc. Just think of all the stories we've heard of people trying to avoid hitting deers, turtles, squirrels, cats, dogs, etc., etc., etc. That's when there is only one of the animals too...can you just image a whole horde of them.
