No matter how many efforts to get people out of their cars and walking/cycling, town planning, and especially many of the new build estates popping up without infrastructure seem to be pushing us in the other direction.
I quit driving due to a surgery 2 years ago and apart from the dreadful mess the trains are in at the moment, I haven't looked back. I didn't change my diet, but becoming a ton fitter and slimmer was a nice side effect. I planned to return to using a vehicle but am in two minds now.
Granted, I have no children at home who need driving around, and I live close to some decent walks, but I have this feeling the way the country is heading, we are becoming less and less able to reduce car use.
Visiting my family last week I noticed my home town has become chock with traffic, most shops are out on retail parks now and there are very few cycling paths or places to walk. With so little attention to improving public transport I can't see this getting any better. And once you atart walking everywhere, you realise that there are more roads than pedestrian spaces in a large, typical town. And it stinks, which I never noticed so much when I was driving myself.
People discuss processed foods and sedentary jobs when looking for reasons to explain rising obesity, yet few people look at increasing car use as a factor.
