The figure in the media is selectively presented spin.
The proportion of over 70s involved in smacks makes up 9 and a bit percent of casualties, whereas they make up 14% of drivers. So, far from the worst demographic.
However, the number of driver deaths for over 70s is around 21%. Hardly surprising as theyre more likely to be infirm, less resistant to injury, and less able to heal effectively.
Whichever way one looks at it, the most dangerous demographics remains the 17-23s, followed by the 24-30s.
