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

Waymo has now paused its self-driving car service in five US cities, in response to a software issue which has seen some vehicles enter Flooded roads and get stuck.The US firm recently issued a recall of thousands of robotaxis following an incident on 20 April in San Antonio, Texas when an empty Waymo vehicle entered a flooded road and was swept into a creek.Following a similar incident in Atlanta, Georgia, a Waymo spokesperson said it had expanded the temporary pause to five cities - four in Texas as well as Atlanta - "out of an abundance of caution".The company told Reuters it had also suspended services on US freeways as it works to improve its cars' performances in construction zones.The company, which hopes to operate a robotaxi service in London later this year, told the BBC safety was its "highest priority"."We continue to closely monitor forecasts, alerts, and live weather conditions, and we will resume serving riders soon," it said. The software problem, which could allow vehicles "to slow and then drive into standing water on higher speed roadways" was highlighted in a letter posted on the National Highway Traffic Safety Administration website earlier this month.In response, Waymo issued a voluntary recall of nearly 3,800 of its robotaxis that use the company's fifth and sixth-generation automated driving systems, and said it was working on "additional software safeguards".
