Uber Robotaxis Hit Zagreb Streets

Testing Underway Zagreb

Public road validation for Europe's initial robotaxi operations began in Zagreb, Croatia, on April 2, 2026, as Uber, Pony.ai, and Verne initiated hands-on trials with Arcfox Alpha T5 vehicles equipped with Pony.ai's Gen-7 autonomous driving system. Riders in the Croatian capital now encounter these driverless fleets integrated directly into the Uber app, allowing seamless booking alongside conventional rides. Verne, a Rimac Technology subsidiary based in Zagreb, manages fleet operations and regulatory navigation, while Pony.ai supplies the core self-driving tech tested rigorously over the past week. By April 5, early data from these runs showed smooth urban navigation, marking a pivotal moment for autonomous mobility on the continent.

Partnership Roles Defined

The collaboration solidified during meetings in Zagreb from April 3 to 4, with Uber committing investments to Verne for fleet expansion and Pony.ai optimizing its systems for European roads. These Arcfox Alpha T5 models, built by BAIC Motor Corp., offer a 273-mile WLTP range, suiting dense city routes without frequent recharges. Unlike prior U.S. or Chinese pilots, this effort emphasizes full commercial viability from the outset, with vehicles already appearing in Uber's ridehail network. Industry observers noted on April 6 how Croatia's supportive regulations accelerated this timeline, positioning Zagreb ahead of larger markets like Germany or Great Britain.

Experts Eye Transformations

Autonomous transport specialists hailed the April 4 joint statement from Uber CEO Dara Khosrowshahi, who stressed ecosystem integration for global scaling. "Europe needs services that transition from tests to reality," Verne representatives affirmed, predicting reduced reliance on human drivers and lower urban congestion. Analysts project this could challenge traditional ridehailing economics, with Pony.ai's battle-tested tech—proven in Asia—adapting swiftly to local conditions. Safety metrics from the week's validations exceeded expectations, fostering optimism among regulators for broader approvals.

Expansion Plans Accelerate

Following successful April 6 evaluations, the partners outlined scaling to thousands of vehicles across additional European cities pending data reviews. Uber's platform will prioritize robotaxi matches in eligible zones, with Verne handling maintenance and Pony.ai refining software via real-world inputs. Regulators in neighboring markets expressed interest by week's end, signaling potential rollouts within months. This momentum positions the trio to lead Europe's shift toward driverless fleets, reshaping daily commutes.
