Source? In my experience it's unexpected incursions, whether that be cars changing lanes, pedestrians stepping off the sidewalk or food-delivery bikers yeeting themselves into an intersection.
In the city stop and start is primarily determined by traffic lights, which are predictable, rather than the traffic itself.
