Waymo pauses robotaxis in five US cities after cars drive into flooded roads

Coverage Comparison

Multiple reports from the BBC detail the sequence of events leading to Waymo's decision. The first report, published shortly after the incidents, focused on the pause in service across five cities. The second, published minutes later, emphasized the recall of thousands of vehicles. Both reports draw on official statements from Waymo and the National Highway Traffic Safety Administration (NHTSA), as well as commentary from an academic expert.

Key Claims

• Software issue and service pause: Waymo paused its self-driving car service in five US cities due to a software issue that caused some vehicles to enter flooded roads and get stuck, according to reports from the BBC.
• Incident in San Antonio: An empty Waymo vehicle entered a flooded road and was swept into a creek on 20 April in San Antonio, Texas, as reported by the BBC.
• Recall of robotaxis: Waymo issued a voluntary recall of nearly 3,800 robotaxis that use its fifth and sixth-generation automated driving systems, per the BBC's reporting.
• Suspension of freeway services: Waymo also suspended services on US freeways in San Francisco, Los Angeles, Phoenix, and Miami, as it evaluates vehicle performance in construction zones, according to a company statement quoted by Reuters and reported by the BBC.
• Temporary updates: Temporary updates limiting where affected vehicles can drive during extreme weather have already been applied, according to an NHTSA letter cited by the BBC.
• Company's commitment to resume: Waymo said it expects to resume service soon after rolling out necessary software fixes, as reported by the BBC.
• Expert commentary: Jack Stilgoe, professor of science and technology policy at University College London, told the BBC that all self-driving car systems have limits on when and where they can operate safely, and such limits often become apparent only when something goes wrong.

Perspectives

Waymo's perspective: The company emphasized caution and proactive measures, stating it paused services "out of an abundance of caution" and continues to monitor weather conditions closely. Waymo expressed confidence in its ability to resume services soon after implementing software safeguards.

Safety regulators' perspective: The NHTSA letter indicates that temporary updates have been applied, reflecting regulatory oversight and the requirement for corrective actions before service resumes.

Academic perspective: Professor Jack Stilgoe highlighted that while autonomous vehicle technology holds promise, safety limits are often discovered through incidents, and policymakers would prefer to know about these issues in advance.

Article

The recent incidents involving Waymo's self-driving vehicles have led the company to temporarily pause its robotaxi service in five US cities, following a software issue that caused some cars to drive into flooded roads and become stuck.

According to reports from the BBC, the issue came to light after an incident on 20 April in San Antonio, Texas, where an empty Waymo vehicle entered a flooded road and was swept into a creek. A similar incident was reported in Atlanta, Georgia, prompting the company to expand its temporary pause to four cities in Texas as well as Atlanta, "out of an abundance of caution," as a Waymo spokesperson told Reuters.

In response to these events, Waymo issued a voluntary recall of nearly 3,800 of its robotaxis that use the company's fifth and sixth-generation automated driving systems, according to the BBC. The company stated it was working on "additional software safeguards" to prevent such occurrences.

Additionally, Waymo has suspended its services on US freeways in San Francisco, Los Angeles, Phoenix, and Miami while it evaluates the cars' performance in construction zones. The company told Reuters it expects to resume these routes soon.

According to a letter from the National Highway Traffic Safety Administration (NHTSA) cited by the BBC, temporary updates limiting where affected vehicles can drive during extreme weather have already been applied. The letter suggests that regulators are closely monitoring the situation.

Jack Stilgoe, professor of science and technology policy at University College London, commented to the BBC that all self-driving car systems have limits on when and where they can operate safely. "We often see these limits only when something goes wrong," he said. He added that as more autonomous vehicles are deployed, more such problems are likely to emerge, and that this does not necessarily mean the technology will not be beneficial, but policymakers would prefer to know about these issues in advance.

Waymo, which is owned by Google's parent company Alphabet, has seen significant growth in its robotaxi operations, providing more than 500,000 trips per week across multiple US cities, as noted in the BBC report. The recent incidents raise questions about the readiness of autonomous vehicle technology for widespread deployment, although the company has emphasized its commitment to safety and its intention to resume services once the necessary software fixes are in place.

The pause and recall highlight the challenges that autonomous vehicle companies face as they expand their operations. While the technology has the potential to transform transportation, incidents like these underscore the importance of rigorous testing and regulatory oversight to ensure public safety.

As Waymo works to address the software issues, riders in the affected cities will need to rely on alternative transportation options. The company has not provided a specific timeline for resuming full service, but its statement suggests that it expects to do so soon.

Over the past year, several incidents involving different driverless car firms have raised concerns about robotaxi safety, indicating broader industry challenges beyond Waymo's current situation.
