This is what we call normal traffic on San Francisco's one-way streets. There are lanes for parking on either side. There are lanes for double-parking on either side. There is one traffic lane in the center.
San Francisco has pairs of one-way streets, one east bound, one westbound. The lights are timed to keep traffic moving at around twenty-five miles per hour. Used properly they would be efficient means of moving around a city with the worst traffic congestion in the USA (yes, worse than you, NYC).
They are not used properly. People try to drive forty miles per hour on them and end up creating stop-and-go traffic. And people double-park. Delivery trucks double park because alleys for making deliveries are extremely rare. Also, Uber and Lyft started here, seemed to assume they could double-park, and no one ever told them they couldn't.
When I call this "normal traffic," I am not exaggerating. Mid-day, you cannot drive more than three blocks in any direction without encountering the kind of situation shown here. Doesn't this make you want to ride an electric scooter on the sidewalk?
