CaoCao Mobility, the ride-hailing subsidiary of Chinese automaker Geely, will integrate May Mobility's autonomous driving technology into its fleet operations across Europe, according to announcements from both companies. The partnership gives Ann Arbor-based May Mobility access to CaoCao's operational infrastructure in multiple European markets while providing the Chinese platform with proven autonomous technology that has logged over 400,000 passenger trips across six U.S. markets. Financial terms were not disclosed, though May Mobility CEO Edwin Olson indicated the deal structures revenue sharing based on deployed vehicle count and trip volume rather than a flat licensing fee.
May Mobility operates shuttle-style robotaxis in Sun City, Arizona; Grand Rapids, Michigan; and four other North American cities, using a technology stack the company describes as "multi-policy decision making" that runs multiple AI models simultaneously to select the safest driving option at each moment. The system differs from the end-to-end neural network approaches favored by Waymo and Tesla, instead combining traditional path planning algorithms with machine learning models trained on specific scenarios. That architecture has allowed May Mobility to secure partnerships with Toyota and NTT in Japan, though those deployments remain limited to closed campuses and geofenced routes under 15 miles per hour. The CaoCao partnership represents a significant escalation in operational scope, targeting public roads in urban environments at normal traffic speeds.
CaoCao launched in Hangzhou in 2015 and now operates in 60 Chinese cities with a fleet exceeding 100,000 vehicles, primarily electric cars manufactured by Geely brands including Geometry and Zeekr. The company has invested heavily in electric vehicle adoption but lags behind Didi Chuxing in autonomous vehicle development, with only limited pilot programs in Suzhou and Wuhan using technology from partner AutoX. Geely's broader autonomous driving efforts have centered on subsidiary Ecarx, which supplies infotainment systems and driver assistance features to multiple automakers but has not deployed fully driverless taxi services. The May Mobility partnership allows CaoCao to leapfrog years of in-house development while maintaining operational control of the rider experience and fleet management.
European markets present regulatory complexity that neither company has fully navigated. Germany permits autonomous vehicle testing under strict supervision requirements, while France and the United Kingdom have announced frameworks for commercial robotaxi deployment by 2027 but have not finalized safety certification processes. May Mobility's existing deployments operate under temporary exemptions or pilot program authorizations rather than full commercial licenses, a regulatory approach that does not translate directly to European Union member states with varying national rules. CaoCao has no existing European operations, meaning the partnership must build service infrastructure, obtain operating permits, and establish maintenance facilities from scratch. Industry observers note that established ride-hailing platforms including Uber and Bolt already operate at scale across European cities and are pursuing their own autonomous vehicle partnerships, giving them distribution advantages CaoCao will struggle to match.
The partnership reflects broader consolidation trends as autonomous vehicle companies reassess pure-play technology strategies. Argo AI shut down in 2022 after Ford and Volkswagen withdrew funding, redistributing its engineers to the automakers' internal programs. Aurora Innovation acquired Uber's self-driving unit in 2020 but has since pivoted toward freight trucking rather than passenger services. May Mobility raised $111 million in Series C funding in 2023 and has consistently emphasized partnerships with fleet operators rather than building its own consumer brand. Olson stated in investor presentations that the company targets 10,000 deployed vehicles by 2028, a figure that requires multiple partnerships of the scale represented by CaoCao. The international expansion also diversifies regulatory risk, allowing May Mobility to continue growing revenue even if U.S. certification processes stall or public acceptance remains limited in specific markets.
What to Watch: Look for specific city announcements from CaoCao and May Mobility by Q3 2026, likely starting with German markets where Geely already maintains dealership networks and service infrastructure. Monitor whether CaoCao secures fleet financing for European expansion or partners with local leasing companies to minimize capital deployment. Track May Mobility's U.S. deployments for operational metrics that might predict European performance, particularly incident rates and rider acceptance in Sun City, which most closely resembles the geofenced urban routes likely in initial European launches. Pay attention to responses from Waymo and Cruise, both of which have explored European expansion but face different regulatory pathways as subsidiaries of U.S. automakers.
