This thing is a package delivery robot that was waiting at an intersection to cross the street. It was in 'testing mode' and had two young guys walking with it. It seemed vulnerable to abuse to me, so I think it will be some time before these things on the streets without escorts; however, they do seem like they would work well for large corporate campuses. I imagine with time they'll start blending into the background, that and the cameras recording all the activity around them will probably make them less of a target for abuse.
