I think the design-fu is mixing up the message as it's not really clear what you're trying to do/say with it.
I don't think it will serve cycling very well if you make it antagonistic (
what's the point in trying to be clever or wind drivers up?) - but I like the idea of using the common "How's my driving" layout theme - which most people easily recognise - so maybe change the wording to put a positive spin on it?
Something along the lines of driving safely around cyclists (
even if they aren't - the irony might 'ping' them to think about it a bit more?) or maybe thanking them for leaving plenty of room? That sort of thing ...
Just my 2p worth ...
