One Hundred Cars and a Single Point of Failure

What's happening

At least 100 of Baidu's Apollo Go robotaxis simultaneously stopped in the middle of traffic in Wuhan, China, following what police described as a "system malfunction." Videos posted on social media showed autonomous vehicles frozen across the city, with one appearing to document a highway collision. No injuries were reported, and passengers exited safely. Baidu has not responded to requests for comment. The incident follows a pattern: in December 2025, a power outage in San Francisco caused Waymo robotaxis to stop and block traffic. In August 2025, an Apollo Go vehicle carrying a passenger in Chongqing fell into a construction pit. Uber and Lyft announced partnerships with Baidu in December 2025 to bring Apollo Go to UK roads. Professor Jack Stilgoe of University College London noted that while driverless technology may be safer on average, it can "still go wrong in completely new ways."

What the text says

Psalm 127:1Unless Yahweh builds the house, they labor in vain who build it. Unless Yahweh watches over the city, the watchman guards it in vain.

The psalm opens with a conditional: unless. The Hebrew im lo is emphatic. If the Lord does not build the house, the builders' labor is wasted. If the Lord does not watch the city, the guards stand watch for nothing. The psalm is not anti-construction or anti-vigilance. It is a warning about the foundation. Systems built on human coordination alone contain a vulnerability that no amount of engineering can eliminate.

The psalm was attributed to Solomon, the greatest builder in Israel's history. Coming from him, the words carry additional weight. The man who built the Temple, the palace, and an empire's infrastructure writes that building without the right foundation produces nothing lasting. The psalm does not condemn ambition. It questions what ambition rests on.

The reflection

One hundred vehicles controlled by one system. One failure, and all of them stop. The efficiency that makes a fleet of robotaxis attractive is the same architecture that makes them fragile. Human drivers in Wuhan would have produced fender benders, road rage, and the occasional wrong turn. They would not have produced one hundred simultaneous points of paralysis. The psalm does not say building is foolish. It says building that assumes its own sufficiency is. A city that hands its mobility to a single system has placed a bet the system will never fail. The psalm was written for that bet.
