Each vehicle continues to operate with a trained safety driver initially, with both companies targeting full driverless operation by year-end pending regulatory and performance assessments. Uber now partners with over 20 autonomous-driving developers globally, including recent agreements with Amazon-backed Zoox for steering-wheel-free vehicles in Vegas this summer and Los Angeles next year. Uber has relaunched its autonomous ride service in Las Vegas using Hyundai-Motional Ioniq 5 vehicles integrated into the Uber app for UberX, Uber Electric, and Uber Comfort customers at no extra fee. The company plans driverless rides in 10 cities in 2026 and expand to 15 cities by year-end, aiming to reduce per-ride costs, improve profit margins, and solidify its aggregator platform in the robotaxi market.
