The self-driving race is shifting into high gear, and Uber just added more horsepower. In a new multi-year partnership, Uber and autonomous vehicle (AV) company May Mobility will begin rolling out driverless rides in Arlington, Texas by the end of 2025—with thousands more vehicles planned across the U.S. in the coming years.

Uber said it’s signed a agreement with Chinese autonomous driving comppany Momenta to deploy robotaxis in international markets starting, with Europe in 2026.
