Britain is probably the only country in the world where electric vehicle use is declining, due to the rapid disappearance of the electric milk delivery vehicle, or milk float.Until recently it was common place for milk to be delivered to almost every house in the UK, daily. Presumably in order to secure the national flow of tea. To achieve this a vast army of distinctive, cheap looking, sluggish, electric utility vehicles paraded suburban streets.Here are some different varieties, including new concept vehicles and milk floats from movies, all preserved for posterity.
