It's a lifesaver, simple as that. Statistics reflect the scale of the problem, particularly amongst boys.
Other countries of the world, including the USA, Canada, Australia, South Africa and Hong Kong, limit the driving freedom of new teenage drivers. My favourites are:
- For the first 12 / 18 months the only passengers that can be carried are parents or siblings
- Driving is prohibited during certain night time hours
- Speed restrictions apply
- Size of engines are restricted
Research is best undertaken in the UK not only with insurance companies but also the drivers of breakdown lorries who pick up the mess off the roads. They will tell you the incidence of young people in over-powerful cars, which I gather is anything over 1200cc.
