“generally”? I live in an area of the USA where AFAIK bicycles are officially dual-mode and allowed to be on both roads and sidewalks, and have been on both sides of pedestrian/bicycle encounters on sidewalks in the past, without any major issue.
From the article it sounds like the Pennsylvania legislature has already considered the case of delivery robots specifically and decided that they should go on the sidewalk, though to what degree that reflects the popular will is unknown to me.
