David Price played a major role in the following high profile cases:

  • Expert for Lord Steven’s enquiry into the death of Diana, Princess of Wales fatal car crash in Paris (examined the Mercedes S280 and its numerous component parts, and produced a 282 page report on them)

  • Hyundai (rear suspension)
  • Ford (seat belts)


and investigations into

  • Kässbohrer/Setra coaches (ABS sensor wiring failure caused by poor installation design) – many fatalities
  • Corbeau racing seat collapse (this led to an RAC Motorsport rule change regarding seats) – fatality
  • Sanderson (rear suspension of Teleporter) – fatality



Other important investigations, albeit not necessarily as high profile, have included:
