I didnt have the heart to tell him that sat nav hadnt been invented the first time I did it. Or indeed the second time, when I came out of KwikFit on to a dual carriageway and somehow crossed one set of lanes too many. You would have done the same. It was very confusing.

Tony foresees eventually expanding his operations, either in Minnesota or elsewhere, into a sort of military-reenactment theme park. Participants would take part in a make-believe war zone, but with real equipment. The vehicles could all be fitted with laser-tag equipment, making it possible to act out a large battle scene.

"The Prime Minister's decision to put Lord Browne of Madingley, the former head of BP, in charge of an "efficiency unit" just when he is talking about ending the reliance on outside agencies has also been questioned. The betting is that like so many of his predecessors, Lord Browne will be eaten for breakfast, no doubt at the Athenaeum.

In an important speech to Policy Exchange last week, David Willetts, the science minister, set out why Britain could steal a march in eight major areas of technological innovation, from making computer switches out of bacteria to printing out an aeroplane. This focus on encouraging business on any scale to invest and take risks in this country relies on unsung work. David Cameron and Mr Osborne, for example, have instructed their offices that there is always room to be made in their diaries, even at short notice, for a company executive looking to seal a deal. Achievements in developing Britain's hi-tech entrepreneurship sit in a wider context of necessary Government reforms that are steadily recalibrating the economy. Corporation tax is being reduced, bank lending encouraged, investment for small and medium businesses made 10 times more attractive, small business rates eased, research tax credits multiplied: the list of measures introduced is numbingly long; the results have yet to be felt. Ministers congratulate themselves that the number of private sector jobs has risen by 250,000 in a year, and that welfare reforms will incentivise work. They can almost smell the growth that will come in a few years' time.
