Normally, electric or electrified cars are launched to the media in urban settings, never far from an emergency recharge point, but Nissan clearly had confidence in the newly extended range of its latest Leaf - a theoretical 250 kilometres or, in old money, 155 miles. Hence a coffee stop 1,607m above sea level at a place called Col de Turini, to which we had scampered up from Nice, had another 78km to run, had a thoretical range of 25km left on the 'fuel gauge' and there was zero chance of a reviving fast charge. Merde!
