I moved to a new city a few years ago and began to slowly increasing my cycling commutes. It got to the point where my car and motorbike were used about once per month each so I ended up selling them off. Despite not using them I was so used to having them that it felt like a mistake at the time - but it has surprised me that I've been fine. It has changed my views on cities immensely as far as the detrimental effect that private cars have on them. The needless traffic noise, emissions, energy expenditure, space required, cost of fuel and parking etc just doesn't seem to make sense - when I never gave it any thought previously. To combat such problems a number of cities are moving towards being car free or reducing cars in the inner city. Some very successfully. I never realised that european cities like Amsterdam have a fairly short history of being cycling/pedestrian-centric where now over 60% of inner city trips are made by bike; The above opinion article goes on to make some further associations between less cars and increasing wealth (which i'm not sure follows - the increased wealth could easily come first): Those cities cited are of course the densely populated and prime to improve public transport/short commutes by foot/bicycle. I was wondering what locals of other cities have experienced as far as the above interventions/town planning to reduce car use in both terms of good and bad outcomes. What has worked and what has died in your local vicinity? Has it made your city a better place overall?
