Waymo is a self-driving subsidiary of Alphabet. The commercial autonomous ride-hailing service was first launched in the Phoenix suburbs this December in what appears to be a breakthrough in the self-driving technology that has been worked on for almost a decade now.

To start with, only members of an elite test club “The early riders” will be allowed to use Waymo one, these people serve as a focus group for further understanding the self-driving taxi. The privileged early Riders have actually been testing various prototypes of the company’s autonomous vehicles since last year. Now some of these riders will now move to test the much anticipated “Waymo One”.
Besides the recently announced self diving taxi, the company’s self driving Chrysler pacifica minivan has been around for a while.
The taxi company Waymo has not released any information on when exactly it plans to roll out the 21st century taxi scheme to the general public. This might not be unconnected with the fact that further research and tests are still being conducted as regards the viability of the scheme.
As it stands, Wamos taxis are not totally driverless yet but the company has pledged it will eventually offer driverless rides in the nearest future.
