How to make the roads safer?

There's a book, Cyclecraft, which is modeled on the police driver training book Roadcraft. I haven't read it but mean to. It's meant to be good.

As above, it is probably due a minor update, but it is excellent. I bought it, not really expecting to get anything from it, and was very pleasantly surprised. I've since lent it to a work colleague who is using it to teach his 10 year old daughter to ride her bike on the road, which is nice.
