"Personally, I think the age in which people are allowed to drive should be raised to 21 - especially for young men."
Well, I don't think that would be a great ideaflip_flop. It's hard enough for a chap to have to fork out the insurance premium as it is. Increasing the age just for males would be gender discriminating, and make it so jobs involving the use of a vehicle of that kind harder to get for younger people. So many implications would arise from such a change.
Even though I am a young male who pays through the nose because I'm 24, I do understand why. I see stupid looking modded fiestas and saxos all the time. They're invariably driven by lunatic teenage boys who think that having an oversized exhaust is an extension to their manhood. Not everyone is the same, but it's about statistics.
Of course, I don't agree with the statistics when it comes to very elderly drivers. They are NOT the safest on the road. They might not have as many accidents, but that's because they don't drive over 30mph. That isn't safe on a motorway, but it doesn't stop them. They avoid accidents because their ignorance and crap driving is more predictable for other road users than that of a boy racer's. It's still dangerous, it's just that statistics don't measure it the same.
