stop signs and flow

I watch this video about stop signs being bad, and one big argument was how they disrupted flow for cars and bicycles (assuming no Idaho/rolling stop for bikes). You move, you stop, you move again.

As a life-long pedestrian I've always thought stop signs were great, and this helped elucidate why: they don't hurt my flow. In fact, they optimize it, compared to North American alternatives anyway. No waiting 30-120 seconds for a walk signal to change. No waiting for a break in traffic at an uncontrolled intersection. At most, wait for a car already there to clear, then walk. Ideally, a walk with stop signs is very close to a walk without any cars around. Pretty neat!
