Waymo is doing alright in San Francisco as well. That's not directly comparable to Tokyo, either, but I expect it's a much less distant of a comparison than Phoenix.
In SF you still have clearly delineated sidewalks with curbs and crossing lights. Japanese side streets are basically equivalent to alleys and cars are guests. There aren’t too many streets like that in the US at all.
I saw a video of a bunch of Waymos backed up on each other being too hesitant to make a turn. Kinda reinforced a fear I have of these things. Not to mention I would hate to try and wave one of these things to turn before me... or wink my headlights.
IDK, like I get the appeal for driverless cars, I just still don't like them.
Seeing something once doesn’t make it a real phenomenon.
Besides, if that is common, Waymo will have data on it and if it’s common enough, they’ll fix it.
I’ve sat in Waymos on 2 occasions, each on a separate ride, in which the car avoided collisions that would have happened due to bad human drivers. Your fear is worth examining closely as it’ll hold you back from enjoying this amazing technology.
I think you may mean something other than phenomenon ("an observable fact or event"). Seeing anything more than zero times makes it a phenomenon by definition.
