§ Mr. Hooleyasked the Secretary of State for Transport if he will amend his past calculations of road vehicles in use, which form the basis of transport planning. to take account of errors of method in arriving at the figures.
§ Mr. William RodgersThe costs involved in amending past estimates would not be justified, as the changes would be small relative to the total vehicle stock.
§ Mr. Hooleyasked the Secretary of State for Transport, in the light of the fact that the present method of calculating the annual vehicle census produces an over-estimate of the order of 400,000 vehicles, if he will now return to the system of counting all vehicles licensed on any one day as was done between 1939 and 1945.
§ Mr. William RodgersIt is already planned to carry out a full census of vehicles currently licensed as at 31st December. This will be made possible when all vehicle registrations are held at the Driving and Vehicle Licensing Centre.
