Engineer Jem Stansfield investigates how the crash test dummy has become an icon for safety. For 65 years he has been crashed, smashed and impaled, evolving from a simple military mannequin into a highly sophisticated measuring tool. Jem meets a whole range of dummies from the past, present and future at crash laboratories in Sweden, the UK and US to discover how their evolution has mirrored car safety improvements. An affectionate look at a unique feat of engineering which makes you laugh, gasp and wince all at once.
