Motional builds fully driverless, all-electric robotaxis for urban transportation. Its vehicles operate within ride-hailing and delivery networks by partnering with these services to provide autonomous mobility options. The cars use advanced sensors and software to navigate city streets safely, while a real-time Command Center monitors every robotaxi, allowing human agents to supervise operations, offer remote assistance, and ensure passenger safety. Motional differentiates itself through continuous real-time oversight, a scalable B2B model, and a focus on integrating autonomous vehicles into existing mobility networks rather than selling to individual consumers. The company aims to make driverless transportation safe, reliable, and accessible at scale, reducing costs and increasing efficiency for partners and riders alike.

Hyundai's Motional aims to deploy robotaxis at lower costs than Waymo

Hyundai-backed Motional has relaunched robotaxi operations in Las Vegas through Uber, two years after pausing its commercial service to overhaul its technology and reduce costs. CEO Laura Major told Business Insider the company can now deploy robotaxis more cheaply than competitors like Waymo. The company shifted from specialised models to "Large Driving Models" that adapt across geographies, whilst cutting 40% of its workforce to 700 employees. Motional's integration with Hyundai allows cars to arrive from production lines with sensors and compute power pre-installed, avoiding costly retrofitting. Currently operating with safety drivers, Motional plans fully driverless service by end-2026. The company will partner with ride-hailing platforms rather than launch its own app, with plans to license technology to other operators for fleet management.

Uber and Motional launch commercial robotaxi service in Las Vegas

Uber and Hyundai Motor-backed Motional launched a commercial robotaxi service in Las Vegas on Friday, marking the latest partnership as Uber expands its self-driving taxi strategy. The company has committed over $100 million to develop autonomous vehicle charging hubs. Las Vegas users can hail Motional's IONIQ 5 electric robotaxis through Uber's app at no extra cost. The service covers key areas including Las Vegas Boulevard, Resorts World, Downtown Las Vegas and Town Square near the airport. The vehicles will initially operate with human safety operators, with fully driverless service expected by late 2026. Motional's IONIQ 5 is among the first Level 4-capable autonomous vehicles certified under US Federal Motor Vehicle Safety Standards. Uber has recently partnered with Amazon's Zoox, Baidu, Nissan and Wayve to expand autonomous offerings globally.

Uber robotaxi rides are now available for passengers in Las Vegas

Uber robotaxi rides are now available for passengers in Las Vegas. They will start showing up as an option in the Uber app. Contributing Reporter Fri, March 13, 2026 at 5:00 AM PDT Uber's and Motional's Hyundai Ioniq 5 autonomous EVs will start appearing as an option for riders in Las Vegas. Passengers requesting for an UberX, Uber Electric, Uber Comfort or Uber Comfort Electric ride may be matched with a Motional robotaxi. They will not be forced to take it, though, and will be notified and given the option to decline and choose a regular ride instead. But if they want to try it, they can boost their chances of getting matched with a robotaxi ride by opting in via the Ride Preferences section under Settings. Riders who get on autonomous rides will be able to unlock the vehicle through the Uber app. Inside, they'll hear audio cues reminding them to close the door and fasten their seatbelt. They'll also be able to access human support through the Uber app in case they need help. The companies started piloting the robotaxi service in Las Vegas in 2022 after establishing a 10-year partnership. Motional's Hyundai AVs were also tested by Uber Eats for autonomous deliveries in the same year. The first autonomous rides under the partnership will still have safety drivers behind the wheel to monitor the roads. They will also be only available, for now, at designated locations along Las Vegas Boulevard, "including rideshare zones at the Resorts World Las Vegas and Encore at the Wynn Las Vegas - plus Westgate Las Vegas Resort & Casino and curbside in Downtown Las Vegas and throughout the Town Square shopping district near the airport." By the end of the year, the companies expect to start offering fully autonomous rides with no human operators. They have plans to expand the rides' availability throughout the city, as well. Uber has also just announced that it's piloting a robotaxi service in Tokyo in late 2026 in partnership with UK self-driving car startup Wayve and Nissan. In addition, the Uber-backed Nuro will test its own autonomous vehicles in the Japanese metropolis soon.
