Abstract
At present public attention is focussed largely on technological developments for decreasing dependence on oil based fuels. These include electrically driven cars, and alternative portable fuels such as hydrogen. Another development avenue is increasing the availability of petrol for motor-cars by exploitation of new oil sources. Developments in electronics and computers could have a major impact on control systems and communications. An interlocking system of public transport could provide much of the versatility and usefulness of the private motorcar which could diminish in number.
