This is such a laughably dismissible idea, I don't even know where to start: navigating sidewalks and crosswalks autonomously is even more difficult than autonomously navigating the roadways (what with all the standardized signals, markings, rules, etc.) and yet here we are pitching it as if we already have the technology to accomplish this to any useful degree. Is it going to locate and push the correct crosswalk button to make sure it has a chance to cross the street safely and legally? Also, what are these things going to do when drunk (or otherwise unhelpful) passerby inevitably kick them over, rendering them completely immobile? This is 100% innovation theater.
