Is making the Queen's Quay and Bay Tunnel bus-compatible possible? Or is the turning radius at QQ too small and the tunnels may be too narrow?

In short, not possible without severe modifications. The tunnels throughout the whole thing are pretty much too narrow for that kind of operation.Is making the Queen's Quay and Bay Tunnel bus-compatible possible? Or is the turning radius at QQ too small and the tunnels may be too narrow?

To start with, turns will be an issue, since a streetcar is on a track it makes every turn the same way every time. Bus drivers are turning a big analog controller and so the turns will vary. Even on straightaways a bus will not go perfectly straight as drivers must continually make corrections, but a streetcar doesn't need the same margin. All this means a streetcar can get away with a narrower lane, and when you're building a tunnel, you'll likely build the narrowest one needed for your target vehicle.Are they? Buses are barely any wider (102 inches vs. 100 inches) than streetcars.

Try turning a bus in one of those narrow tunnels and see what the end result would be.Are they? Buses are barely any wider (102 inches vs. 100 inches) than streetcars.

Guided buses are problematic, as Adelaide is discovering, not to mention that for Onion Station, as the layers are peeled back, those 'guided buses' would have to be electric, as there's no ventilation for internal combustion vehicles.A guided busway could solve this problem. It's basically a bus that runs on tracks:

SO WHAT ARE OTHER CITIES DOING?
Cities in the United Kingdom, France and Germany have been investing heavily in light rail infrastructure in recent years.
Professor Currie said there was "overwhelming evidence" that the likes of trams bolstered activity levels and urban density around such transport corridors.
"These are very efficient and improve job opportunities, commercial development and economic activity in inner areas and improves life quality."
He said buses were currently the majority carrier for Adelaide, but "unfortunately they share the road space with traffic so they're reasonably slow".

You may not have noticed but stretcars are on tracks so have little or no possibility of veering off course, buses can and do move around and need more space.Are they? Buses are barely any wider (102 inches vs. 100 inches) than streetcars.
Certainly worth a few cans of paint and, as you say, cheap. Of course, ;people who miss rumble strips, signs and flashing lights will probably ignore or not notice paint but ....I have said it before and I will say it again.
Painting the ROW will vastly enhance everyone’s awareness that it is a no-go zone for vehicles or pedestrians. It’s easy, it’s cheap, it has been employed elsewhere in the GTA and it’s effective.
Can anyone explain to me why this either hasn’t been considered or if so, been rejected?
Presumably there is concern that a) it snows and b) when it doesn't snow, there is a lack of urgency to maintain. Crosswalk lines are usually faded to almost nothing before the city renews them, for example.I have said it before and I will say it again.
