PRESTO Martinez shared autonomous minivans are free!

Use the May Mobility app for booking (available in Google Play and App Store), or call May Mobility at 925.995.3797. 

Riders can enter any address within the service zone for pick-up and drop-off in the app. The app will assign you to a nearby “virtual stop,” a safe, pre-approved location for the autonomous vehicle to pick you up or drop you off. PRESTO Martinez is a fleet of shared autonomous minivans; like an Uber Pool, other travelers traveling in the same direction may join your ride. 

Yes. On the app, riders can input any address within the entire service zone for their pick-up and drop-off. The app will assign you to a convenient nearby “virtual stop” that has been pre-vetted as a safe place for the AV to start and stop. For riders who prefer not to use an app to book, call 925.995.3797 and an operator will book the ride for you.

Wheelchair accessible minivans can accommodate one wheelchair and two additional riders.

Other minivans can hold up to four passengers at a time.  

Although the vehicles are self-driving, each PRESTO Martinez autonomous minivan features a human safety operator to ensure safety, answer questions about the service, and assist riders in wheelchairs. 

The PRESTO Martinez autonomous minivans can handle all sorts of situations and hazards on the road, reacting quickly with safe, predictable vehicle movements. The vehicles can handle both cold and warm weather conditions. In case of an emergency, the human safety operator staffed on each ride may take control of the vehicle as an additional safety measure. 

In 2019, The Contra Costa Transportation Authority was awarded the Automated Driving Systems grant and the SB1 Local Partnership Program to be used toward providing an on-demand, wheelchair-accessible AV service to people without reliable transportation to medical appointments and hospitals.
