Right then (cracks knuckles) here goes nothing - groans from forum members logging off.
The first thing you must accept that, to mis-qoute Sting, "There is no monopoly of common sense, on either side of the age related fence."
When I first started driving, in my Mum's Viva HC, I was 17 and although I grew up in quite an affluent, aspirational area, more than a few of my friends had access to a car, although 17 year olds in general didn't. The roads were much quieter than now and most of my mates drove their parents' cars so perhaps we/they felt some kind of responsiblilty to them that they wouldn't have felt in their own motors.
I got my first car in 1978, a Vauxhall Chevette with a monumental 58bhp to play with. Almost the same as a much more modern Punto 1.2 and yet it took about 15 to 16 seconds to get to 60, much slower than a Punto. I once had a race (yeah I know) with what I thought was a 1.1L Mk 1 Escort. It turned out to have had the engine replaced with a 1.6 Mexico engine. To say I was comprehensively trounced is an understatement. In fact, the tyres crippled so much under cornering I got a lecture from my Dad about kerbing the tyre.
What does all this mean? Well, we all did things when we were younger that we wouldn't do now. I could tell you one or two other things that might surprise those who've read and taken part in my posts.
So what has happened in the meantime? I suppose the easy answer is that I got older and grew up. But when did that happen? Well, it certainly didn't happen over night. It didn't happen when I turned 18, and it didn't happen when I became 21 either. I probably became more mature day by day and it wasn't a consistent development either. I became more reliable at work but was still trying to jump on any female I could find.
We don't suddenly become more mature all round; male testosterone doesn't miraculously diminish when we get the key of the door, so although there may be merits to raising the driving age, to what level do you raise it? Recently I had to attend two damage only RTCs within 40 hours of each other on the same bend involving cars travelling in the same direction and both driven by people who worked within a mile of where the crash happened so knew the road well. Both cars crashed on a 40 limit road by skidding across the opposing carriageway, hitting the kerb, rotating through 180 degrees and ending up in a ditch. Only luck dictated that there were no cars coming the other way; or a 44 tonne truck, or even worse a cyclist or pedestrian.
Both drivers were in their 30s. The first words out of both their mouths were: "I wasn't going fast" which virtually guarantees they were. So is 35 too young to learn to drive?
From a personal perspective as a Driving Instructor and with the Police I would rather there was some form of graduated licence. For example, as a new driver, regardless of age, on passing the present driving test he/she would be limited to 1.4 litres and 70bhp. In addition they would have to stay within 25 miles of the home address and not be able to use motorways. After taking a kind of IAM/ROSPA test, more powerful cars could be driven and motorways used.
That in itself cannot guarantee safe drivers, only individual responsibility can do that.
As for the young vs old question.....this is more like "Voluntary Manslaughter" as opposed to "Involuntary Manslaughter." One may result in a death because one person decides to teach another a lesson by putting a Nitro-Glycerin (heart treatment) tablet in a mate's cup of coffee to make him sick as a joke. Another person dies because his friend is old and accidentally puts a Nitro-Glycerin tablet in the coffee instead of saccharin. A death still results but the cause is different. One is a result of a malicious act, the other a careless mistake.
I hope johnw doesn't read that last paragraph, he'll have something to say about my analagy.
