Speed is usually not an issue on city roads. Turns and blind spots are bad. Some people try to pass just so they can get to the next red light quicker. Usually if its congested enough that its not safe for a car to pass a cyclist the cyclist is usually able to go faster than traffic. Cars lose a lot of time decelerating and accelerating for frequent stops. Its even an annoyance to the biker because on car is hit about wanting to pass and then the biker keeps waiting at intersections for cars to get up to speed.
