A TV documentary several years ago with a head on country lane incident between a Dsi Jazz and another vehicle,, the Jazz driver , in his 60s, remained conscious and aware and talkative, his long-term medical needs from the accident, a knee injury corrected by an artificial knee joint
The other driver, in his 30s, driving an old car was in a terrible state, as an older car, the front of his car simply destroyed , there followed a jaws of life extraction with full monitoring by the medics through the extraction, just as well, as the driver entered cardiac arrest during extraction, and required resuscitation, so severe his injuries , at the hospital he was placed in an medically induced coma to save his life.
The programme ended with an interview with the surgeon and an X-ray plate showing shattered legbones of the driver of the old car. The surgeon said, "the worst leg injuries I have ever seen" then adding " the other leg was the same".
The old car was so badly damaged it was not easy to identify by TV viewers, but I think it was an old Fiesta of the mid 1980's.
Watching the documentary showed how much progress has been made in occupant protection in a crash, that even our elderly Dsi Jazz cars fared so well in an incident is encouraging.
