Streetcar tracks are definitely a challenge in the city. Probably the root cause of ~1/3 of my friends reported crashes (unabashed anecdata). I ride on fatter tires than I would like in order to avoid getting stuck in em. Certain intersections are just a total mess of tracks (Queen/King/Roncesvalles for example), so I just go to pedestrian mode and walk my bike across the crosswalk there.

So yeah, it's definitely top of mind if you're riding on those streets, but there are things you can do to mitigate risk down to a level that's acceptable for me. For the record I live in Toronto, drive to work, all other trips are on my bike unless there's snow on the ground.
