What Would You Do?

While surfing the internet, I came across a study which was done 20 years ago, not even 10 miles from where we live. In it the scientists (?) placed either a black hose or a serpentine-shaped rubber snake in the median of a rural highway to see whether people would go out of their way to hit what they thought was a snake. They found that the rubber snake was much more likely to be hit than the hose. Duh! They had to do a study to figure that one out?
