Starship food delivery robot traps wheelchair user in the street

This seems to be a relevant topic for discussing unintended side effects of automated systems.

You can build a robot that can navigate the usual aspects of the city - but can you ensure that robots can also navigate the unusual aspects, which are rare but very important, such as needing to move aside from a curb cut so that a wheelchair user can get on the sidewalk instead of being stranded in the street when the green light ends and cars start driving there?
