   “They noted: "The crashworthiness of the early carriage was of a low standard. By the end of the 19th century, the continuous automatic brake and the absolute block system had greatly reduced the accident rate, but the accidents that did occur often reduced the wood vehicles to matchwood."”

   “But then crashworthiness is not about preventing accidents, but about mitigating their consequences.”
