Social media is brimming with photos, videos and commentary about the on-going power outage in EssEff from a sub-station fire. It peaked at about 130,000 customers and the last 20,000 or so might get power back tomorrow morning (that would be two days of no power). Aside from all the other inconveniences and possible dangerous situations, we can now add confused and disabled Waymo’s to the list. Per the Comicle:

Waymo’s autonomous ride-hailing service remained suspended Sunday morning after a sweeping power outage knocked out traffic signals across large swaths of San Francisco.

On Saturday, videos shared widely on social media showed Waymo vehicles stopped mid-intersection with hazard lights flashing, forcing other cars to maneuver around them. Waymo halted service citywide around 8 p.m. Saturday.

The outage started “late Saturday morning” but Alphabet didn’t take the robotaxis fully out of service until 8 p.m. even though the software can’t treat a missing traffic light as a four-way stop. And some cellular internet service was affected which Waymo needs to work. Go figure.

I took my first Waymo ride three months ago with a couple non-dangerous wrinkles as noted here. But we have very erratic PG&E power in town. Just this morning I got a Citizen app notice of two outages in the B’game-H’borough area. There was a major outage about a week ago as well and we don’t particularly handle failed traffic lights well in town either. Putting a sawhorse in the middle of ECR with no lights or a flare that went out an hour ago is standard protocol.

You may have read about a woman who gave birth in a Waymo on the way to the hospital a couple of weeks ago. Better to stick with Uber or Lyft if it’s urgent.

One response to “No Mo Waymo: Power outage chaos”

    I hope you are all having a safe, warm, dry Merry Christmas. Christmas Eve was dramatic. 70 mph gusts and downpours, but the electricity held up at least where I am. Today there is a possibility of lightning and hail. The Chronicle reports about last Saturday’s big power outage of 130,000 people in SF are rife with quotes about how happy people were that they had a gas stove. Truer words have not been spoken. “Across the region, 123,865 PG&E customers were without power at 8:30 a.m. on Christmas morning, the utility reported.” Also from the Chron:

    In a blog post published Tuesday, Waymo said the unprecedented number of dark traffic signals strained safeguards designed for smaller outages. Its vehicles are programmed to treat nonfunctioning signals as four-way stops, but in some cases they request a remote “confirmation check to ensure it makes the safest choice.”

    “While we successfully traversed more than 7,000 dark signals on Saturday, the outage created a concentrated spike in these requests,” the company said, adding that delays in confirmations contributed to congestion on already overwhelmed streets.

    Waymo said it is already rolling out fleet-wide software updates that give vehicles more context about regional power failures, allowing them to navigate intersections “more decisively.”

    The company also said it is updating emergency preparedness plans, expanding coordination with city officials and continuing first-responder training, noting that more than 25,000 responders worldwide have already been trained to interact with its vehicles.
