Guided by cameras and radars, and negotiating traffic and roundabouts, a self-driving Nissan car took to the streets of London on Monday for the carmaker's first European tests of an autonomous vehicle.

Traveling at up to 80 kph and moving from local streets to a major multilane road, the modified Nissan Leaf electric car showcased the kind of technology many hope to be the future of travel.

Britain has been wooing developers of autonomous vehicles, hoping to grab a slice of an industry it estimates could be worth £900 billion ($1.1 trillion) worldwide by 2025.
