I've actually been wondering if at least some "road rules" issues are related to this. At least in my city, I think a large portion of young cyclists simply don't know the rules of the road and the conventions of safe road use. Without getting a driver's licence, how do young people learn some of the less obvious parts of road etiquette and safety?

I'm not trying to open a can of worms here, and I'm a commuter myself, it's just something I've been wondering a lot lately. How I drive (and learned to drive) I think informs my cycling, and is one of the reasons I've had so few incidents - I bike defensively. I've often wondered how my habits on the road (on my bike) might be different if I'd never learned to drive.
