I think @DanAndrewsMP gets it perfectly, when on talk-back radio it's safest to be anti-bicycle. Same government just knocked back footpath cycling (one less thing to fine bikes for) and introduced fines for using a phone on the bike to same level as car drivers (because bikes are just as dangerous). These are all anti-cycling. BTW footpath cycling is not ideal but it's one less thing the police can fine cyclists for.
In actual fact the project is continuing and I've been talking to CoM in the last week, trying to ensure that safe footpath adjacent-but-separated-lanes is one of the options being considered. At the moment I'm waiting for news to come back from the tree people to verify what CoM told me about 5 years ago, viz the trees are all so old they need to be replaced, which means we can consider new locations for them. I do have a contact name at Vicroads as well but want to get CoM point of view sorted first. When we know more, we can hopefully arrive at a joint position with PPBUG and put our point of view.
Regarding representation by BN, they are agreeing to the centre-of-the-road proposal and when queried on this by PPBUG Garry's response was (I have this 2nd hand) that they weren't interested in member input.
If the thought is that Vicroads proposal is bike lane all the way from tram track to median, I took a look today when I rode an O-bike down there and in places there are 2 car lanes in that space so I hardly think that is all going to be given to bikes.
Where I disagree with Jonathan, is that prioritising faster cyclists will perpetuate the minority status of cycling because most people who aren't cycling now will not want to do that. Average speeds in high-cycling countries are 15-20 km/h. Higher speeds are possible if the path is wide enough, and with the design I'm proposing sight lines will generally be good enough to make that comfortable and safe as well.
Centre-of-road lanes might be OK if there are also smaller lanes alongside the footpaths for local, slower, access but I doubt we can get both. There also needs to be plenty of separation from cars if in the middle of the road, which would need the whole space between the existing medians to become grass, trees, tram and bike space. Note that the current median trees can't be replanted closer to the centre because of rules about the view of the shrine.
