Alphabet Inc (GOOGL.O) is expanding its testing of self-driving cars to the Phoenix, Arizona metro area, the company said on Thursday, making it the fourth U.S. city to serve as a proving ground for the autonomous vehicles.
The company’s Google unit has conducted driverless vehicle testing for six years in Mountain View, California, where it is based, and expanded testing to Austin, Texas last summer. In February, Kirkland, Washington, which is home to significant wet weather, was added as a testing site.
