Alphabet’s Waymo said on Thursday it has suspended its robotaxi service on freeways in the United States and paused its operations in Atlanta, Georgia as it updates software to improve performance around construction zones and flooded roadways. The suspension comes as Waymo, which has been growing its robotaxi operation slowly and steadily for years in the U.S., has quickened the pace of expansion, as others, including Tesla and Amazon’s Zoox, step up their push in the sector. “We have temporarily paused freeway operations, as we work to integrate recent technical learnings into our software and expect to resume these routes soon,” a Waymo spokesperson said in an email.
