You guys have no idea what you're talking about. You learn from your mistakes and close encounters. Yes, you need to be mature (and racing out of a car park when you've only just passed is totally ridiculous), but when you first pass your test you want to take your mates out, and they inevitably cause distractions you've never had to drive with while you were learning - you might as well get used to them sooner rather than later. It's a cliche but you don't actually start learning to drive properly until after you've passed your test and you're left to drive on your own. There are plenty of us who have never crashed but there are just as many, if not more, who have dented a wing or something, purely through making a simple mistake. We're all human, we are allowed to make mistakes, and ultimately that's why we have compulsory insurance to fall back on.
With such negative attitudes to driving you probably are best off the roads.
