Google unveils its own self-driving cars
Google is starting to build its own self-driving car, rather than modifying vehicles built by other manufacturers.
The car will have a stop-go button but no controls, steering wheel or pedals.
It will seat two people and will have an electric propulsion. At the start, its speed will be limited to 25mph (40km/h) to help ensure safety.
It will depend on Google's road maps, built specifically for the programme, and tested on the company's current fleet of vehicles.
The BBC's Jack Stewart spoke about the car.
