Hands-free on the road?

Google's driverless car project was officially launched推出 in 2010. Since then it says its test vehicles have completed more than a million kilometres on public roads. They've progressed from relatively simple driving on the Californian freeway to more complicated manoeuvring機動 in urban areas.

So far, Google has used a fleet of ordinary cars, which have been converted to carry self-driving technology. But now it wants to take the process a stage further by producing a purpose-built特製的 machine. It’s planning to create a fleet of about a hundred fully autonomous electric vehicles capable of carrying two people at up to 40 km per hour without any input from a human driver.

The ultimate aim最終目標 is to get rid of the controls altogether, although early versions will still need to have a steering wheel方向盤 and pedals.

Google believes it will be able to launch a pilot scheme using the new cars within the next two years. But the internet giant is far from being the only company working on self-driving technology. A number of major manufacturers have their own test programmes, among them Ford, Toyota, Volkswagen and BMW.
