[ 5 ] Google's driverless car project was officially launched in 2010. Since then it says its test vehicles have completed more than a million kilometers on public roads, from relatively simple driving on the Californian freeway to more complicated maneuvering in urban areas.
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 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 kph without any input from a human driver. [ 6 ] The ultimate aim is to get rid of the controls altogether, although early versions will still need to have a steering wheel 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. [ 7 ] A number of major manufacturers have their own test programs, among them Ford, Toyota, Volkswagen and BMW.
