Following what the hon. Member for Cornwall, North (Mr. Pardoe) said, will my right hon. Friend bear in mind that if the worst comes to the worst and a petrol rationing scheme has to be introduced, the situation in rural areas is now totally different from that when the last petrol rationing scheme was introduced? Whatever the situation in London, rural bus services are now virtually non-existent in parts of the country. Since the distances are longer and there is a higher dependence on the private motor car in all income groups, if rural areas are not given special concessions a high proportion of the rural population will not get to work at all.
