quality remembered/crash test dummies

摘要

In the 1930s, as US auto fatalities reached 15.6 per 100 million vehicle miles, car manufacturers began to pay serious attention to safety. Initially, human cadavers were used in a series of gruesome experiments to test auto safety during collision. It wasn't until 1949 that a research lab, led by engineer Samuel Alderson, created 'Sierra Sam', the world's first crash test dummy. However; between the time of Sierra Sam's invention in 1949 and 1966, there was no set standard for the dummies being produced, making it difficult to collect reliable data. They were primarily only used in testing air-craft seatbelts.
