Yep, I do it (and love it) here in Melbourne Aus. all the time...the cops CAN charge you with crossing lines without indicating etc. IF they can be bothered chasing you, but are reasonably tolerant if you are not too dangerous in your interpretation....the freeways are an example where traffic is stopped through peak times, so up the middle I go and then you get the wankers that move over so you cannot get through, it's then into the breakdown lanes...$140 fine for that, (once again if they can catch you)...that hit on the siren couldn't possibly be for me officer...surely ha ha...Kahil Gibran (The Prophet) cited:- (Man delights in making laws...but he delights MORE in breaking them)...how true...I feel so sorry for the motorists in their cages with windows... that have to sit in traffic and wait their turn....
