Service Pauses and Freeway Suspension
Waymo halted driverless taxi service in several cities and suspended all freeway trips nationwide because of flooding incidents and concerns about construction zones.
Background & Context
Alphabet’s Waymo operates robotaxis in multiple U.S. markets, delivering over 500,000 rides weekly and targeting one million. Recent flood-related mishaps prompted a temporary scale-back.
Timeline
- Apr 20 2026: An empty robotaxi was swept into a creek in San Antonio.
- May 20 2026: A vehicle became stranded on flooded streets in Atlanta.
- May 22 2026: Waymo announced pauses in six cities and halted freeway service.
- May 22-23 2026: NHTSA issued a letter flagging software that could drive into standing water on higher-speed roads.
Data & Statistics
- Weekly rides: >500,000.
- Recall: ~3,800 robotaxis (fifth- and sixth-generation systems).
- Cities paused: reports list five or six (four Texas cities + Atlanta, with Nashville mentioned).
- Freeway routes suspended: San Francisco, Los Angeles, Phoenix, Miami.
Official Statements & Responses
Waymo said it paused service “out of an abundance of caution” for forecasted severe weather and reiterated safety as its highest priority, adding it is monitoring conditions and will resume when safeguards are ready. NHTSA identified a software flaw that could cause vehicles to enter standing water on higher-speed roadways, prompting the recall.
Criticism & Opposition
Riders expressed unease about flood handling; Vanderbilt researcher Derek Gloudemans cited the “long-tail problem,” noting autonomous systems struggle with rare events like sudden flooding and that expanding to varied climates will reveal further challenges.
On-the-Ground Reports
Video captured a Waymo robotaxi stuck in Atlanta floodwater for about an hour. Nashville rider Julie Moore described the episode as “a little unhinged,” while another rider, Courtney Weyers, said she would still try the service “skeptically.”
Conflicting Reports & Gaps
Sources differ on the exact number of cities paused (five versus six). Waymo has not detailed the specific construction-zone issues behind the nationwide freeway suspension, and the effectiveness of the recent software patch remains unverified.
Verbatim Quotes
- “It felt a little unhinged getting in it, but I was a fan, but now that I saw the flooding, I don’t know,” — Julie Moore, rider, Nashville
- “He said AI and autonomous vehicles often struggle as they learn how to react in new scenarios, known as the long-tail problem.” — Derek Gloudemans, research scientist, Vanderbilt University
- “We continue to closely monitor forecasts, alerts, and live weather conditions, and we will resume serving riders soon,” — Waymo spokesperson (BBC)
- “to slow and then drive into standing water on higher speed roadways” — National Highway Traffic Safety Administration letter (BBC)
What’s Next
Waymo will refine flood-detection algorithms, add software safeguards, and test performance in construction zones before restoring freeway routes. Ongoing weather monitoring will guide the timeline for resumption.
