Google is to start building its own self-driving cars, rather than modifying vehicles built by other manufacturers.

谷歌将着手打造属于自己的自动驾驶汽车，而不是在其它厂商的车型上修改。

Google says it expects its self-drive cars to be on the road 'within a year'

The car will have a stop-go button but no controls, steering¹ wheel or pedals.

Pictures of the Google vehicle show it looks like a city car with a "friendly" face, designed to make it seem non-threatening and help people accept self-driving technology.

Co-founder Sergey Brin revealed the plans at a conference in California.

"We're really excited about this vehicle - it's something that will allow us to really push the capabilities² of self driving technology, and understand the limitations," said Chris Urmson, director of the company's self-driving project.

He added that the cars had the ability to "improve people's lives by transforming mobility³".

But some researchers working in this field are investigating potential downsides to driverless car technology.

They believe they could make traffic and urban sprawl⁴（城市扩张） worse, as people accept longer commutes⁵ as they do not have to drive themselves.

Flexible windscreen

The BBC was given access to the Google team to talk about the secret project, and see early renderings⁶ of the car.

It looks almost cartoon-like, it has no traditional bonnet⁷ at the front, and the wheels are pushed to the corners.It will seat two people, propulsion will be electric, and at the start it will be limited to 25mph (40km/h) to help ensure safety.

The most significant thing about the design is that it does not have any controls, apart from a stop/go button.

For early testing, extra controls will be fitted so one of Google's test drivers can take over if there is a problem.

The controls will simply plug in, and Mr Urmson believes that over time, as confidence in the technology grows, they will be removed entirely⁸.

The front end of the vehicle is designed to be safer for pedestrians⁹, with a soft foam-like material where a traditional bumper¹⁰ would be, and a more flexible windscreen, which may help reduce injuries.

The vehicle will use a combination of laser and radar¹¹ sensors¹² along with camera data to drive autonomously¹³.

It will depend on Google's road maps, built specifically for the programme, and tested on the company's current fleet of vehicles.
