Waymo’s driverless cars can now be booked through the Lyft app in Nashville, making it the first market where the same autonomous fleet is available through two competing rideshare platforms.

The service covers central Nashville, including Downtown and Broadway, North Nashville and Germantown, East Nashville, Midtown and South Nashville.

Riders can choose Standard, Priority Pickup, Wait and Save, or Extra Comfort, with no additional charge for being matched with an autonomous vehicle.

Availability will expand over the coming weeks, with rides assigned dynamically across the two platforms.

The way the two companies have divided the work is important. Waymo owns the vehicles and handles the driving technology.
