Google reveals plans to increase production of self-driving cars

Head of policy for GoogleX hints it could possibly move towards mass manufacturing of fully autonomous prototypes, ahead of road tests in Austin

As a handful of Google's self-driving cars venture outside California for the first time, arriving on the streets of Austin, Texas, this week, the company has revealed its plans to build many more fully autonomous prototypes, and possibly move towards mass manufacturing.

When Google introduced the low-speed, two-seater electric cars last year, it said it was going to build just 100 vehicles by the end of 2015. But speaking at the California Public Utilities Commission on Thursday, Sarah Hunter, head of policy for GoogleX, said: "We're " making a few hundred of them. We're making them to enable our team to learn how to actually build a self-driving vehicle from the ground up."
