Ya the idea that buses are better than streetcars because they can go around traffic is just completely detached from reality. Maybe a bus can go around one double-parked car but during rush hour that's not happening. It was always just an excuse to avoid taking an inch of space away from cars for dedicated transit right of way.
I live in Toronto and avoid taking streetcars because I have seen significant delays precisely because of parked cars or some other blockage.
Of course in my opinion this simply means banning parking on streetcar routes; or having dedicated streetcar lanes where a blockage simply isn’t possible.
Streetcar routes in Toronto which do not share the road are fine.
