I just mean that the much greater propensity for young people to pass their test and soon after, take a car and smash it, has been well known for a long time. It may have been the main cause of 16-24 year old deaths for a long time. They have certainly been a focus of road safety strategies for a long time. The Scottish Road Safety Campaign's 'Crash Magnets' was designed around them.
I imagine the committee have picked up on it because it has that capacity to catch people out and generate a reaction. It seems counter-intuitive when, as you say, cancers and heart attacks have been seen as the main cause of death and the people who are perceived to die on the road are children. If it's the main cause of death for 16-24 year olds there must be something badly wrong. It's no bad thing that people start taking it seriously but really, the most striking aspect of the recent increase in road deaths is the way that overall, the number of car occupants killed or seriously injured continues to decline but the numbers for pedestrians and cyclists is increasing.
