Robotaxis leave the demo city: snow, stadiums and military bases
Waymo is preparing for winter with sensor heaters and snow tires. Zoox signed a multi-year Formula 1 partnership. May Mobility and Forterra advanced to Phase III of a Pentagon challenge worth up to $30 million.

Winter is the new test track
Waymo's blog post this week is less about a launch than about a limit. The company says it uses a peer-reviewed Safety Framework to validate its technology for specific weather conditions, and it may reduce service areas or pause operations entirely when weather exceeds safety boundaries. Pauses in service can last for hours or days depending on conditions. That is the honest version of winter operations: the car decides not to drive. m:…9092
The engineering behind that decision is substantial. The 6th-generation Waymo Driver uses cameras, radar and lidar for navigation, with built-in heaters and micro-wipers to keep sensors clear, and the system measures real-time traction changes under each wheel to adjust steering, braking and acceleration. Waymo is equipping its winter fleet with snow tires, running closed-course evaluations and heavy snowfall data collection in Alaska this season, and using simulation to recreate black ice and whiteouts. It has tested in Upstate New York, Michigan's Upper Peninsula and the Sierra Nevada, and its vehicles act as mobile weather stations, sharing road and weather data across the fleet. m:…9092
Stadiums, bases and sidewalks
Zoox is taking a different route to the same destination: a public, scheduled, high-profile deployment. The company entered a multi-year partnership with the Formula 1 Las Vegas Grand Prix, becoming the event's official autonomous ride-hail partner, and plans to offer robotaxi rides to and from the Grand Prix Plaza beginning in 2027. Zoox began testing autonomous technology in Las Vegas in 2019 and launched its robotaxi service there in 2025, so this is an expansion of an existing operation rather than a debut. It also already partners with MGM Resorts for dedicated pick-up and drop-off locations. m:…6590
May Mobility and Forterra are heading somewhere with even less tolerance for a missed pickup. The two companies were selected to advance to Phase III of the Department of War Innovation Unit's ROADS prize challenge, an effort worth up to $30 million that seeks to test commercial self-driving vehicles for military installation safety and logistics. May Mobility will provide its autonomous driving system for passenger transport, and Forterra will serve as fleet operator using its OneLink command-and-control system. A month-long pilot at a select Army base is planned, with vendor mapping beginning in November 2026. m:…1950
The numbers behind the bid are worth noting. Forterra has fielded more than 250 autonomous systems for Department of War programs, and May Mobility has delivered more than 550,000 commercial autonomous rides across 1.1 million miles. May Mobility's system simulates up to 10 seconds into the future to evaluate driving strategies. The challenge's premise, that military personnel are frequently pulled from training to drive people and equipment across posts, is a logistics problem that autonomy can plausibly solve without needing to be perfect on a highway. m:…1950
The platform play
Serve Robotics, meanwhile, is turning its own fleet into a product. The company introduced Physical AI Services, a suite that lets other companies use the technology behind Serve's robot fleets, including Serve Link, which connects robots to off-board intelligence and monitoring, and Serve Data Curator, which identifies rare, valuable training data from robot fleets. Bedrock Robotics is a launch customer, using Serve Link to connect machines over Wi-Fi, LTE, 5G and satellite networks. m:…5305
Serve says it has deployed over 2,000 robots in more than 40 cities and 27 hospitals, and supports delivery for more than 4,000 restaurants. The company spun off from Uber in 2021 and acquired Diligent Robotics in 2026. The pitch is that the hard-won operational knowledge of running robots on sidewalks — connectivity, data curation, model training — is now sellable on its own. If that works, physical AI starts to look less like a collection of vertically integrated fleets and more like a stack with suppliers. m:…5305
What changes now
Taken together, the four announcements describe a field moving from demonstrations to deployments with schedules attached: a winter season in Alaska, a Grand Prix in 2027, a month-long Army base pilot, and a platform launch with a named customer. None of these is a claim that autonomy is solved. Waymo's post is explicit that the system will stop driving when conditions exceed its boundaries. The shift is that the constraints are now operational — weather, venues, bases, fleets — rather than technical demos. The companies that can run inside those constraints, and say so plainly, are the ones getting the contracts. m:…9092 m:…6590 m:…1950 m:…5305
For executives watching physical AI, the question to ask is no longer whether the robot can drive, but where it is allowed to drive, for whom, and what happens when it decides not to. Waymo answers with a safety framework and a pause. May Mobility answers with a simulation horizon and a pilot. Serve answers by selling the answers it already built. Those are three different business models for the same underlying problem, and all three are now in the market at the same time. m:…9092 m:…1950 m:…5305
What is still unresolved
- Whether Waymo's winter service pauses frustrate riders enough to slow expansion into snowy metros.
- Whether the Army base pilot converts into a standing deployment after Phase III.
- Whether Serve's Physical AI Services finds customers beyond Bedrock Robotics.
