A JustEat motorcyclist was forced to lay down his bike and slide 30 feet across a roundabout to avoid a driver that pulled out in front of him - and then made off. Bill Griffin, 56 and living in Cringleford, Norwich, was travelling straight ahead at the Sweet Briar Road roundabout as he approached from Guardian Road on April 29 at 6.30pm when he says an erratic driver moving at "terrific speed" failed to give way.
