But that's kind of the point. Doug Ford and many conservatives have always derided the DRL as some excessive line for the urban elite. What you have instead is adequate capacity elevated line, but a overcapacity expensive underground line/lines in suburban areas (or just ridiculous like Eglinton...
No, I definitely don't. The only way I see it changing drastically is if being elevated garners enough blowback for the provincial government to 'direct' them to make changes (and with CAQ having really no seats in Montreal that's pretty unlikely).
Cities are already trialing autonomous microtransit, it's really not far off. Tesla and many companies also have level 3 autonomous modes which can essentially drive themselves with the driver being passively aware.
Don't spend too much money integrating a piece of infrastructure that will be torn down. Automation of cars and telecommuting will make the massive amount of roads we reserve for single occupancy cars unsustainable.
I understand the frustration of how long it takes to plan/consult/build, but those processes have been put in place for a reason. Shortcuts become painfully evident once a project has been completed, simply look at the Canada line with small stations and disruptive construction.
