Sir Clive Sinclair, British consumer electronics pioneer, also developed the C5 electric tricycle and planned to build a wider range of battery-electric cars over time. His progressive idea became a commercial failure, if I understand correctly due to low speed, short range, and lack of weatherproofing. The C5 was only built in 1985 and sold only about 5000 of the 14,000 vehicles built. There are still some C5 fans and preserved C5s like EDP9, which I saw at the Museum of Science and Industry (Manchester, England) when I visited in August 2015.
