Mark Rober, an engineer at NASA, seems to have a little too much time on his hands. For a fun experiment, Rober decided to camp out on the side of a road and analyze how many cars went out of their way to hit rubber animals he placed on the side of the road.

Though it sounds silly, his results are interesting: He found that about 6 percent of drivers (60 out of his sample of 1,000 cars — mostly those in SUVs and trucks) would swerve out of their lane to hit a spider, turtle or snake on the side of the road. On the flip side of the animal empathy coin, almost 6 percent also pulled over to try to help the rubber animals (specifically the snake and turtle).

Watch the whole experiment below more for more details and results.
