Liz, (I'm sure you won't mind me calling you that as you yourself like to address others like theleveller with cutesy names like 'levels' and to object would be just a teeny bit hypocritical wouldn't it?), I think you should be aware that in a 2004 study it was found that over three-quarters of residents frequently drive elsewhere to shop and cycling accounts for just 1.9% of journeys to work, public transport 1.8% and that 'THE LEVEL OF CAR USE THERE WAS HIGHER THAN IN THE SURROUNDING RURAL DISTRICT OF WEST DORSET'

'What is unique about Poundbury is that it has sought to recreate a past that never existed - a time machine to go back to when being a child was idyllic,'
From 'Save Truro'

Prince Charles, who actively discourages his subjects from using cars is himself the owner of two Jaguars, an Audi and a Range Rover and the open-topped Aston Martin that was a 21st birthday present from his mum
True, his sports car has been converted to run on surplus wine and is 'used only occasionally for jaunts around the country lanes of Gloucestershire', all necessary journeys I'm sure, and his other cars have been converted to run on bio diesel no doubt the cost of conversion offset by avoiding paying the 62% tax on diesel fuel
Unfortunately, even if we could all afford the cost of conversion there's simply not enough cooking oil in the UK to take over from diesel entirely according to the government's Better Regulation Commission; current waste oil supplies could only feasibly power around one-350th of the UK's cars (not even 'the 1%' then and there is a very real limit on the amount of biofuel the agricultural sector can realistically produce
