In a study where a fake snake and a fake turtle were put on the side of the road, drivers hit the snake much more often than the turtle, and about three percent of drivers who hit the fake animals seemed to do it on purpose.
U studiji gdje su lažna zmija i lažna kornjača bili postavljeni na rub ceste, vozači su mnogo češće  pregazili zmiju nego kornjaču, i oko tri posto vozača koji  su pogazili lažne životinje učinili su to namjerno.
