The appearance in recent weeks of pink, robotic food delivery vehicles on Toronto sidewalks has caused the City to ponder banning such machines. Councillors will vote next week on this question. The food-delivery robots are owned by Tiny Mile. It’s unclear whether Tiny Mile is just a delivery service or has something to do with the manufacture of the robots. In any case, sidewalks are there for pedestrians. Anyone on foot is vulnerable to the approach of such machines as well as bicycles and scooters from behind.
