The autonomous coolers have been banished to industrial areas and limited to just a few prototypes per company.
San Francisco city officials have established aggressive restrictions on autonomous delivery vehicles, creating more red tape as companies such as Amazon explore ways to automate the 'last mile' of a delivery's journey.
Under pressure from advocacy groups, the city's Board of Supervisors has barred companies from operating more than three prototypes each -- with less than 10 allowed on city streets -- and the robots are barred from downtown areas that experience heavy pedestrian traffic, according to the San Francisco Chronicle.
The move may come as a surprise, given the city's proud status as America's tech hub, however some groups apparently voiced a frightening vision of robots wreaking havoc and making life difficult for seniors, children and people with disabilities.
Vanderbilt computer science professor Douglas Schmidt offered the Chronicle another perspective that considers the general public's potential concerns over losing jobs to automation.
"You've got to figure as more and more people start to lose jobs to automation you'll see this kind of response," he said.
Automation has been killing some jobs and creating others for hundreds of years. Americans generally embraced automation as the country maintained a dominant position in the global economy. Now, in a stale economy, sensational headlines have predicted universal unemployment looming over the horizon.
