Granted, my interpretation of solid white lines may be a little "extreme" - let's forget about that one.
With regard to the signage, the pic shows the Start of Bus Lane sign & we've already established the End of Bus Lane one exists, but here it is again. As it's one continuous Bus Lane with no breaks for side roads etc there is no need for extra signage along the Lane, particularly as it's only 130m long.

I appreciate the viewpoint and I guess it's vital that there's a bit of a different interpretation in this forums to ensure people stay level headed, I guess, but I think it's best to always side with whatever is logical and if it's a fair on the driver.
For example, the first and only sign which indicates the restrictions is right next to the traffic lights, when I think it should be a further past the lights and closer to the start of the bus lane. When turning from Webber Row, you basically have a split second to see the sign and if you've ever drive around in a city you know there's hazards and things that drivers easily can miss due to distractions and the lack of a second sign is not fair, especially if you missed the first one, in my opinion.
