Sidewalks are for people. Will the wheeled robot step aside for a grandmother in a wheelchair or neighbor with MS who needs the full width of sidewalk? What will the robot wagon do when it tips over?
People have legal rights to sidewalks. Wheeled robots do not and should not. As urban landscapes continue to grow, sidewalks are one of the last refuges for millions of people to engage in humanity's oldest form of locomotion.
Instead of pouring gobs of money into robots, marketing and lobbying, a good company would do the right thing that is leaving sidewalks for people.
