Treating it like a stop sign also doesn't work very well when there are huge amounts of pedestrians. As a pedestrian that yesterday meant I got the right of way all the time. For cars it was mayhem downtown.

In contrast many years ago I lived at an intersection that had almost no pedestrians back then and a few times for a power outage limited to our building and that intersection. I enjoyed standing on my balcony and watch traffic. It mostly worked well. Cars did treat it like a intersection with stop signs. There two issues happened though. One was when there was no car already stopped and about 10%-20% of drivers didn't realize there was an intersection with lights out and just raced through it. The other ironically were bicyclists. 90% of the just totally ignored there was an intersection. That was especially scary when they arrived at the same time as one of those cars who didn't realize it either.

I’ve long been curious if people in S.F. who are used to Waymo “behavior” – including myself – behave differently when a Waymo is involved. For the most part, Waymos are extremely predictable and if you’re on the road as a pedestrian, cyclist, or car, are you more aggressive and willing to assert your turn in the road? Curious if Waymo has done a psychological study of how we start to think about the vehicles. I know many runners, for example, that’ll stride right into the crosswalk in front of a Waymo but wouldn’t dare to do that in front of other cars. Similarly, anecdotally people treat public transit vehicles differently than a civilian car: folks are more willing to let them drive even if out of natural turn.
