So it turns out that the car is more environmentally friendly than the train for a family of three or more. That's one in the eye for enviro-nutters. It is also one in the eye for this government's completely muddled and irrational environmental and transport policies. As for the spiralling cost of rail transport... Which reminds me, I have to catch a South West Train today, nothing could fill me with more dread. And now it turns out I'd better off in the comfort of a car.
