I'm not a petrolhead; I don't like cars per se, but appreciate their utility. And I'd love to see public transport improved to the extent that people choose not to use cars (I'd be one of them). But, currently, 80-odd% of people in the UK have household access to a car; for many of them it's essential, and for almost all it massively enhances their quality of life. And let's not forget that, of the remainder, many still benefit from the use of a car e.g. cadging lifts etc., and many more would have a car if they could afford one. The Idea that we're anywhere near a public or political will to do away with private car ownership is crackpot stuff. And, frankly, there's other things we could do to reduce emissions that'd provide more gain for less pain e.g. banning diesel, moving to green energy including household production, better insulation, tree planting.
