i dont think driving age should be increased to 21, there are a LOT of people who absolutely rely on having their own car for work, college, uni
i wasnt one of them and only started driving at 23
what we need are dangerously strict driving tests and much more thorough lessons, anything that filters out the idiots that cause most of the "accidents"!
Think its Sweden, Finland, or such like, that has the right idea.
I believe that youngsters have to start learning to drive a car at around 14 on a private track. They don't get their actual licence and till 21 and you should see what they have to go through during lessons and tests. And part of one test is they have to purposely go and skid a car a full 360 in the wet to experience an uncontrolled skid (probably producing the fore mentioned 'wet and skid' in the process

) .
Would also explain why the Swiss/Finland/other snow bound countries produce such good rally drivers!

.
Mind you the government also believes that its money well spent on training the young drivers in this way, as they end up being safer drivers and the death rate is lower than most other European countries. Possibly due to the education that's part of the learning process.
And also think that if you're an idiot, it only delays the time before you’re passed and get a licence as it's pretty strict.
Of course we'll never have anything like that in this country, as it's down to the usual subject "Cost", comes before life’s
