People always say that we can’t go backwards, we have to go forwards. But what if we’re walking to a cliff? Do we keep going forwards, off the cliff, or do we make a turn, then keep walking forward? I don’t think the large scale abandoning of cars would be a backwards step. I think it would be an amazing step forward in a different direction. I don’t drive, and never have, so maybe it’s easier for me to imagine, especially as I’m still in my mid twenties. I can imagine a world were most journeys are taken by bike, and train for longer ones. I can imagine a world where people chose to live close to friends and family, to their work, where vast retail zones no longer exist. I think too much of the debate here is simply a failure of imagination. Like JTD said, seeing without motor-centric eyes is liberating, terrifying and exciting.
