The letters HPV generally connote America's most often sexually-transmitted virus, but they can also mean something similarly unfortunate: Human-Powered Vehicles. A contest for the latter kind of HPV at Grove City College in Pennsylvania nearly ended in tragedy when this HPV from Olin College (clearly modeled after a diaphragm) lost control and plowed into the crowd.
I appreciate any kind of scholastic engineering competition, but I have to question the efficacy of a drag race that involves one participant crashing and still winning. Maybe Olin College is just that good.
(Hat tip to Andrewaul, who can be seen jumping out of the way of the out-of-control HPV!)
