Self-Driving Truck Accident Draws Attention to Safety at TuSimple

On April 6, an autonomously driven truck fitted with technology by TuSimple Holdings Inc. suddenly veered left, cut across the I-10 highway in Tucson, Ariz., and slammed into a concrete barricade.

The accident, which regulators disclosed to the public in June after TuSimple filed a report on the incident, underscores concerns that the autonomous-trucking company is risking safety on public roads in a rush to deliver driverless trucks to market, according to independent analysts and more than a dozen of the company’s former employees. A TuSimple spokesman said safety is a top priority for the company and that nobody was injured in the accident.
