Driverless cars could imminently be operating on London’s streets, after Nissan announced it had been cleared by the UK government to commence limited trials.

While Google has been testing its own autonomous vehicles on public roads near its Californian headquarters, Nissan claimed that its driverless cars will be the first to hit public roads in Europe—if, that is, the Japanese manufacturer receives final approval from an undisclosed local authority in the UK’s capital.

Nissan’s round of secretive tests will apparently see passengers escorted across a route in a single borough, a spokesperson told Ars, once clearance is confirmed. However, the trials won’t be open to all-comers—instead, politicians, regulators, and safety experts will have access to “real-world demonstrations,” with backup drivers present in the cars at all times.
