Mid-life crisis
I figured something out yesterday whilst cruising in my hairdresser's car.
You know how convertible sport cars are normally driven by middle-aged men with baldy nappers?
The reason is - when you're driving along at a fair old pace with the roof down, the wind kinda comes at you from behind and swirls around your head. This has a whipping effect on your hair, resulting in it flapping against your head like you're being flailed by a cat o' nine tails. It's actually very painful, so you tend to get a bit peeved after a while. So, having no hair is a bit better since there's no such effect, you see.
This doesn't answer the question of why you see lots of women driving them, and they've got very long hair. This is an obvious one though - they're knobbing rich middle-aged men.
