The Japanese government issued its first licence for a self-driving car to Nissan, and the car has the number plate '20 20' to mark the year the company hopes to sell such vehicles to customers.
Although the modified all-electric Nissan Leaf has a number of autonomous features found on other cars - such as automatic lane centering and adaptive cruise control - the car also features the ability to automatically exit motorways, change lanes, overtake slow or stationary vehicles and stop at red lights without driver involvement.
