London Cabbie Knowledge

I read a thing about the Knowledge quite a while ago:
http://blackcablondon.wordpress.com/the-knowledge-of-london-training-to-be-a-london-cabbie-my-experience-of-the-process/

Worth a look. Pity so many cabbies loose all empathy with other road users.

This site actually drove my question. I see loads of moped'd (!) people doing the knowledge but never seen a bicycle personage doing the knowledge. Curiosity peeked I stumbled on the same website - which is an interesting read :)

2-4 years to learn the knowledge, on average. Sounds tough.
