- Evaluate May Mobility's Toyota-backed scaling toward robotaxis
What Is May Mobility?
May Mobility is an autonomous-vehicle company focused on shuttles and microtransit rather than open robotaxi hailing. Backed by Toyota and NTT, it has delivered more than five hundred thousand commercial rides across the US and Japan, building real operational experience on lower-speed, defined-route service before expanding into robotaxis.
Its technical signature is an autonomy approach called Multi-Policy Decision Making, which reasons over many possible futures — what other road users might do — to choose safe actions. In 2026 it signed a roughly 750 million dollar deal with ECARX for purpose-built Level 4 robotaxis manufactured outside China for US compliance, alongside Uber and Lyft partnerships.
💡Key Concept
Multi-Policy Decision Making (MPDM): Rather than committing to one prediction of what will happen, MPDM simulates multiple plausible futures for surrounding agents and picks an action that stays safe across them. It's a principled way to handle the uncertainty that makes urban driving hard.
Core Capabilities
- Autonomous shuttles and microtransit — defined-route commercial service at scale.
- Multi-Policy Decision Making — reasoning over many possible futures for safety.
- Purpose-built robotaxis — an ECARX deal for US-compliant Level 4 vehicles.
- Toyota + NTT backing — a manufacturing and capital path plus Uber/Lyft partnerships.

Key Takeaways
- May Mobility runs Toyota-backed autonomous shuttles and microtransit with 500,000-plus commercial rides.
- Its Multi-Policy Decision Making autonomy reasons over many possible futures to choose safe actions.
- A 750 million dollar ECARX deal advances purpose-built, US-compliant robotaxis.
- The autonomy is genuine AI with real ride volume; robotaxi scale is underway rather than proven.
