An investigator put either a rubber snake, a rubber turtle or a rubber tarantula on the shoulder of a highway and recorded who swerved to hit them. He used a rubber leaf as a control although that might have been harder to see from a car. The results from 1000 vehicles studied were very interesting.
- Four percent of drivers stopped to move the "animal" to safety. (Never the tarantula)
- Six percent swerved onto the shoulder to hit it
- The frequency of attempted animal murder? Turtle- 1% Snake- 1.8% Tarantula- 3.2%
- The "killer vehicles"? Trucks and SUVs- 89% Cars- 11%
