I've said this in another thread (maybe this one) but London's bus drivers are definitely the best i've seen, and they never pull out on me and in most cases give me right of way, doing things like pulling in front of them and purposely going slowly is just going to make them less helpful to cyclists, i'm sure you wouldn't like it if a bus pulled in in front of you and purposely went slowly just to piss you off.
