There is a discussion over on Boards about bikers using the bus lane.
I rarely use the bus lane and there is one most of the way home. I don't use them because I don't want to be pulled over by the Gardai and given a lecture and pay a fine. Some wave you on, some stop you.
When it comes to the law it should be black or white. Make it legal for bikers to use the bus lanes. I see too many near misses with people in cars changing lane without looking or indicating. (I'm not saying bikers are better with their indicators).
So show a bit of common sense on open up the bus lanes!
