I congratulate the Government on their very sensible policies on reducing unnecessary car usage, but is my hon. Friend aware that independent tax advisers tell their clients with company cars to contrive to drive more than 18,000 miles a year, even if that is unnecessary mileage, because they will thereby benefit from the discount at 18,000 miles? Will my hon. Friend reconsider the policy with a view to finding a better way of allowing heavy usage—necessary mileage—while not encouraging unnecessary driving?
