When the General Motors Milford Proving Ground opened in 1924 – 90 years ago this October – engineers lacked advanced tools and technology for safety testing. Judging from this video, some might say the only crash test dummies back then were human.
Engineers today keep their distance during crash tests. No more riding the running boards until seconds before impact. Inside the vehicles being tested are heavily instrumented anthropomorphic test devices – dummies – who capture the data for which engineers once risked their lives.
