... still have to break the law ... "
Could always get off and walk to the button... (I know it defeats the purpose, but I hate anyone saying they have to break the law (like a driver who has to break the law by crossing a double white line to overtake a cyclist) when there are actually simple, practical, steps to avoid breaking the law.
The use of the word 'vast' was deliberate, and more a commentary on how awful it was before. It's not perfect, by any stretch, but it's now properly 'useable', and that left turn is a lot less sharp and narrow than it use to be. The layout would have been difficult to eliminate that if we're also talking about pedestrians having to use this - they need a refuge to cross what are effectively three lanes of traffic there - having a 'straight on' lane for cyclists would see this shunted further down the hill, and split by the cycle lane so requiring them to shuffle right from the path, cross two lanes of traffic, cross a cycle lane, cross a lane of traffic, shuffle left; whereas the current system sees, cross two lanes of traffic, cross one lane of traffic.
As mentioned above, best scenario would have been closed to through-traffic, but we know that was never going to happen!
