It's ok if the bus lanes are mostly travel lanes (ok, not great, there's a pretty strong speed mismatch between bus speed and casual cyclist), but it falls down when it's an area with lots of stops. It can be wall to wall busses in some places in Dublin (quays) where many bus lines meet and there are literally continuous stops for several blocks.
