Guy Nantes was killed in a single-vehicle accident in 1957. This was a family tragedy as he was only 35 year old and was married with a young daughter. The accident is examined and it is concluded that Guy would not have been killed today due to improvements in tyre and vehicle design, and the introduction of seat belts.  In 1957, the death rate on Australian roads was about 21 per 100,000 head of population. That rate rose to 35 in 1970 but now, thanks to improved car design and road rules, the rate has declined to about 4 per 100,000.
