A lot to unpack in the last couple of pages...

As a side note, I've been using Google AI searches for quite awhile now, and I have found that it is very good at constructing a thorough, well written report, drawing the same conclusions that you would yourself (given the same information you would use from the internet), except it does it in seconds, instead of an hour or so it would take to do it yourself. An incredible tool to have.

AI is brainrot brother... it's a good starting point but never good at concluding

. You're better than that.
A few things I want to counter with:
1. Digging a tunnel or building elevated roads for BRT is
a lot of disruption. May as well future proof it with Metro because, believe me, no one is going to want to re-dig those tunnels for when you need metro.
2. Have you seen automated vehicles operate in regular traffic? Automating free-driving vehicles is no where near sophisticated enough to operate safely in busy areas. The safety factor is not there.

I will add to that as well: At-grade LRT can be ok if existing right-of-ways exist that can not support the possibility of Metro trains.

Plus buses are very damaging to roads, so a high frequency bus route also costs the municipality in additional maintenance costs. So the additional capital expense isn't just upgrading capacity but also saving money in other areas. By being more efficient.

I agree. These are, IMO, some of the correct benefits that LRT can actually provide. At-grade LRT has been mis-marketed to the masses as a rapid transit solution. This has led to at-grade LRT to being misused in cities. The Finch LRT, Edmonton, and Calgary, among many others come to mind.
There is a time and a place for at-grade LRT. The Toronto TTC streetcars meet those benefits you described.

By comparison, the Canada Line is a main trunk route that other transit routes connects to. Not really a useful comparison. We would need to compare the LRT's projected ridership growth with the projected growth for other mode options on the same corridor to make any relevant claims as to how future ridership would compare.

The Finch LRT is a textbook case where the wrong technology was selected for the transit solution since the commuters needed speed more than anything. I honesty wish that Toronto had just extended line 4 and phased the project.

I agree. Surface at-grade LRT has its time and place.
It's just that for the last 50 years, in North America, surface-at grade LRT has just been totally wrong for many transit solutions that require speed and reliability.

I think that this is one of the cases where it is worth discussing and not dismissing because surface level at-grade LRT could be a viable transit solution... a solution to what? Well, to your other point:

It's the
speed part that an at-grade LRT won't be able to achieve. As Nouvellecosse had said, you would be using the solution to address capacity, comfort, reduced operational costs, and to open up bus inventory.
I also think that if an Arbutus or Dowtown streetcar system is well-designed with the intention of dumping passengers onto Skytrain lines and popular bus lines, riders wouldn't be riding it for the full length. And the metric that I would propose that should be used are the number of boardings and disembarkments at popular stops like at Skytrain stations and BRT connections.
For example, if someone rode the LRT from Arbutus to downtown Vancouver, I would be saying that they don't know how to commute as they should have transferred to a Skytain line at some point in their journey.
