Olympic Games Lanes

Will they really be able to hand out fines to everyone who rides in a lane? Surely it's a massive waste of police time, no doubt they'd rather be doing other things with their time and have no real beef with cyclists. I imagine given the carnage that'll be caused anyway on the roads that bikes are better off in the olympic lanes for the good of everyone else? Can we assume fines will be handed out for the first few days then given up on as soon as they realise how unsustainable it is...
Is the critical mass mob planning anything fun for the occasion?

I don't think we'll know the effectiveness of it until it happens. On one hand, yes, it seems like an impossible law to enforce, but considering how many police (and army!) will be on the streets, it's very possible there will be enforcement officers on all the Olympic routes. They already post plod on junctions to catch RJLers, so why not try to enforce laws/raise revenues by catching naughty cyclists?
