spongedog unfortunately having a car is almost a must for anyone who wants a job unless you live in a city. Public transport options outside of cities and big towns is almost non existent or unbelievably crap. Unemployment rates would go up massively if you can't drive until 25 !! My 20 year old niece is training to be a paramedic. She needs a driving licence as part of the job.
I do understand that as I have lived in a village for the last 25 years. We are fairly close to London, but I couldnt use the bus to the station as the last one home was about 5pm. Not even useful for local work.
I agree with StrawberryLipstickStateOfMind that it is mostly young male drivers causing the issues - death or severe injury to themselves or passengers (often female), damage to property, inconveniencing other road users, NHS,/(air-)ambulance costs. So increasing by a year would have a positive impact.
But there needs to be other restrictions. Perhaps restricting engine size on the vehicles?
This thread started off talking about the need to protect young people from others actions. But who is a young person? Is it 18? Or should we, as a society, still guide and support young people to mature so they can protect themselves from harm.
