Does GM use human bodies as crash test dummies? That's not the plot of a 1970s cult classic; it's the claim of one car-safety specialist in Sweden, who told newspaper Expressen that GM recently wrapped up a multiyear research study using human cadavers in car-crash simulations. The man says Saab cars were involved in the project, which reportedly involved people who had donated their own bodies—assumedly in the name of scientific research—not political dissidents. Well, that's a relief.
