Roadkill Experiment Shows That Six Percent of Drivers Are Sadistic Animal Killers

Mark Rober from NASA makes some awesome videos, but this science experiment must be his best yet. He basically showed that six percent of the drivers out there are sadistic animal killers.
This is what he did:
 • He alternatively placed a rubber animal—and a leaf as a control object—on the shoulder of a road: a turtle, a snake, or a spider.
 • He watched one thousand cars pass by and annotated the drivers' reaction.
 The results are quite surprising.
