Cycling in Sydney Australia
I think a few people got pinged for not putting their foot down and track standing in Centennial Park when Dunc's laws first came in and they took it to court where it was thrown out. Pretty sure it was dangerous riding though. Did a little google and couldn't find anything so might be a figment of my imagination.
Just checked the link from Bob and it's mentioned in the comments (and that it was un confirmed), so the only* bit I might of imagined is them getting off...
* someone else imagined the first bit if it isn't true
