Letter: The 'green car' already exists

ALAN RIDGE'S attempt to build a green car is entirely laudable but misconceived ('And the ghost said to Alan: 'Now build me a green car' ', 18 April). The car may be 'miserly with petrol', and boast 'lower component costs', but will continue to use petrol and will still require several hundred kilograms of steel and plastic components.

Should Mr Ridge be successful in eliminating these barriers, he will no doubt expect it to run along an expensive, unsightly and most unecological road network at speeds which continue to threaten the lives of pedestrians and reduce our town centres to racetracks. There is some good news however; the 'green car' already exists. It is called the bicycle.
