Nowhere in politics is there such a mismatch between public and private realm as in transport. Everyone on the M6 last weekend would have agreed with Transport Minister Alasdair Darling's reported hatred of cars. They too wanted drivers off the roads and on to public transport. Go to it, Mr Darling, they cried in unison, get rid of all those cars. Except, of course, their own. Other people's cars are traffic. My car is the outward essence of my being. It is my hat, stick and cane. It embodies my freedom as a citizen and my right as a democrat. My car is my soul in flight.
