Jeff Woolf of more than six million randomly placed and sized dots per square inch. MicroMap and Woolf were discussed during a debate on innovation in the House of Commons. During this debate, a MicroMap viewer was handed around for members of parliament to use. Woolf worked with Ron Hickman, inventor of the Black & Decker Workmate and designer of the Lotus Elan car, to some extent, benefiting from his patent experience before the final patent application was lodged. MicroMap was patented in many countries around the world. There is a display on the development of MicroMap in the Science Museum in
Lotus Elan to increase the interior dimensions considerably to meet the car's maxim that it "must be capable of transporting two adults and two children 1,000 miles in comfort with their luggage"". While the Elan ceased production in 1973 the Elan +2 continued to be produced until 1975, eventually being replaced by the Elite II and Lotus Eclat. Aside from the increase in size necessary to accommodate two additional seats, the design of the Elan +2 was extremely similar to the two seater Elan. The concept of a backbone chassis with fibreglass body, powered by a Ford UK-derived drive train was maintained.
