Just out of curiosity, can anyone report on how the robots act in terms of right of way? Lets say the sidewalk narrows around an obstacle like a tree or trash can or lime scooter or whatever. If the robot approaches the constriction at the same time as an elderly pedestrian, how does it behave? Will it pause instead of entering? Will it back up a bit when a human would do so to be polite? Will it crowd in someone walking with a cane? In short, what are these things like to be around?
