If anything, the streetcars now seem to be going slower than ever down King, as though the schedules are still set on the assumption that the congestion is still there. Sure, you get an occasional driver who floors it in the morning, especially before 8:00 a.m., but after that, it's really not much to write home about because of the TTC's own scheduling.
Beyond that, travellling from King and Parliament to King and University each day still feels like a chore. The vehicles still hit most, if not all of the red lights. Often they will sit at the farside stops while people slowly and continuously trickle in. They still plod through the center of the financial district mid-day because there's now 100 taxis at all times between Bay and York and for whatever reason they seem to constantly be making u-turns at all points. They still slow for the stopped delivery vehicles in the curb lanes because they are so close to entering the envelop of the streetcar lane space. The drivers seem to be under orders to drop to 10 kp/h whenever they see pedestrians whom might cross the street.
