Driverless car trials are happening all around the UK, but the epicentre is arguably Greenwich, in London. We've seen driverless pods ferry passengers around the O2 and autonomous delivery vans drop off Ocado hampers near Woolwich. That's because a chunk of the borough has been ring-fenced as a "Smart Mobility Living Lab" for autonomous projects and research. The latest initiative to fall under that banner is "Merge," which will look at how a driverless ride-sharing service could work in the city. The work will be led by Addison Lee, alongside a consortium that includes Ford, the Transport Research Laboratory and Transport Systems Catapult.
