On a serious note, has everybody else found that he or she has mellowed with age?
In my mid-late twenties, I'd fly off the handle in the car really easily. I was doing a 40-50k miles a year job, driving a fairly powerful fast car, thought I was king of the road, never did anything wrong, nobody was better at driving than me except the rest of the less than average skill drivers....you know the schtick.
Now that I'm older, I just take it easy, nothing's more important than just getting there safely, in one piece. I try my best to stick to the rules of the motorway, probably exceed the limit occasionally, try to maintain lane discipline, watching in wonder as all the nutters treat the road like it's some kind of battlefield, only to see the same nutters one or two cars ahead at whatever slip road I'm exiting.
I come along behind a slightly doddery old git in front of me and think "that's my mum, that is". She's a bit doddery now, and has had one accident in all her years of driving (the old bump into the car in front in crawling traffic) but now I see how nervous she gets when "young" drivers drive up her arse, overtake stupidly, flash lights. In her seventies, other parts of life seem to fly by at the speed of light for her. But still, she manages, doesn't crash, pays eff all insurance because of it. So, I hang back, and just let the old folk to it. They have to get around and the buses are shit. And they've been around a lot longer than me.
We're all like rats in a fookin cage these days. We co-exist until there just isn't enough space for us, then suddenly every other guy is "trying to nick your spot in the line of traffic" or undertaking you or generally being a far worse driver "than me".
Spread a little love around folks...every day, let one other car out that you normally wouldn't (even if for me, that means at least once every day, I'll let a 4x4 out into traffic or flash them to pull out on the m-way...painful, but just do it). And then let one other car out that's just a very uncool car. It's easier to be nice and just relax...you'll feel a lot better for it. Calm down everyone. It's only metal, plastic and tarmac. It ain't really that important.
