You can hector me all you like, Matt. I'm not the target you seek, however. I already do my shopping by bike, drive the smallest car I can reasonably live with (a Fiesta), and agitate for greater cycling and pedestrian provision at every opportunity. I don't live in a city or town, so my direct experience of, and influence on, the problems of urban congestion are limited. But I'm also a realist, and I understand that people need to be persuaded, not told what to do. If you - and by 'you' I mean local or national politicians - attempt to impose major lifestyle changes on people without a mandate to do so, they will resist and you will have lost. If you convince, by the power of argument and example, people that a different behaviour is beneficial, they will - maybe reluctantly, and with some wailing - accept the changes and learn to live with them. In essence, that is happening now. No, it's not fast enough and the intermediate goals aren't sufficiently ambitious for those already convinced of the benefits, but that's because the argument has not yet been won. It won't be won by diktat, however much you wish otherwise.
