San Francisco let these things loose on the streets earlier this year. While there haven’t been any fatalities, many accidents have already happened. There’s no real point to driverless taxis except to avoid paying people to drive them, especially in cities that have priced the labor pool out to the exurban hinterlands.
As a pedestrian and cyclist, I never want to see one of these things attempt to navigate Boston streets. They’re more of a threat on the roads than this week’s college new arrivals are to the bridges over Storrow Drive.
