This seems surprising. As far as I know all these carts are controlled remotely in real time.

Remote controlled by people in faraway LCOL places where they may not understand or be trained on Western disability norms, but are certainly incentivized by how many deliveries they complete.

I think it depends on the robot. The ones around here seem to be semi-automatic and seem to get taken over by a human when they're blocked, but it often takes 5 or 10 minutes before that happens.
