It's not just Waymo: Mercedes says it's launching a self-driving car service

Self-driving car companies have been testing their vehicles for years, but now regular riders are starting to catch rides in the robot cars. 

Instead of merely watching a vehicle loaded with cameras, sensors, and other equipment drive by, some lucky folks (and not just company employees) are now able to experience the autonomy in person.

Waymo is sticking to its end-of-2018 timeline for a self-driving taxi service in ArizonaGM's Cruise says 2019 is the year for a car service to drive San Franciscans around. And, in Dubai, a self-driving taxi service has already hit the streets.
