I will disagree with one thing - we do slow down on the streetcar network. I don't remember what they do on mixed traffic lines, it's been an age since I rode one, but the Harbourfront car slows at EVERY intersection. I mean good grief, it's one thing to be cautious during poor visibility or even at night, but if you try to tell me that in broad daylight, a professional transit driver can't see a car approaching the track from a decent distance away, I would advise you to shake your head.
The car crawls up the slope out of the tunnel, goes barely faster than walking speed towards York Street, slows even more right before the crossing with York Streey in case our well paid professional driver somehow doesn't see a car approach, then goes barely faster at walking speed onward. Rinse and repeat.
