Lots to respond to and clearly not all directly related to this topic heading but crucial to any debate about the future of the car - first then to the most recent comment re German pedestrians. Yes one of the beauties of the approach is that it reduces casualty rates by introducing an element of uncertainty - now if you get "dozy motorists" or "headless pedestrians" there is greater risk because cars expect to have the roads to themselves while similarly pedestrians think crossings are safe.
Infact today I witnessed an older woman crossing the road, the wrong side of some metal sidewalk barriers - basically taking a short-cut rather than walk down to the staggered crossing. A car hurtling around the corner too fast (and not expecting anyone in the road) only narrowly missed her.
By introducing the concept of sharing the space both have to look out - clearly accidents will still occur but both parties should be more alert.
Second I would like to come back re climate change. While some people may consider that climate change is not man-made, the scientific evidence is now overwhelmingly against them - evidence that some clearly challenge - indeed for many years I was a skeptic - I now consider we cannot take that risk - indeed I think it would be wholly wrong and unjust on future generations.
Certainly some 'green groups' have been guilty of expressing unjustified certainty about the science of climate change, but as the Royal Society has pointed out, the overwhelming misinformation has come from lobbyists questioning the need to cut CO2 emissions. 2,000 scientists from 100 countries who make up the UN Intergovernmental Panel on Climate Change all agree - and their latest report due out next year makes very grim reading. It confirms unquestionably that climate change is a man-made phenomenon and is happening faster and more seriously than previously expected. It is worth noting that not one of the 928 climate change-related articles published in peer-reviewed journals during the past ten years has doubted the cause of global warming, yet more than half of the published articles in the popular press have done just that.
Zac Goldsmith, deputy chair of the Conservative party's quality of life policy group says: "Climate change presents us with an uncomplicated choice. If we are wrong about the dangers, these initiatives come with no downside. But if we are right and we fail to act, the consequences don't bear thinking about."

Thirdly to the point: "It seems to me that the greenies' two doomsday scenarios of enivronmental catastrophe from global warming and the collapse of society through the exhaustion of oil reserves are mutually exclusive." It maybe true that oil reserves running out will reduce impact on climate change but that is unlikely - first we are using such vast quantities and second as oil runs out there will be a rush to more polluting coal etc. We need to act now.
Lastly re population - it is a huge issue that was fashionable in the 70s then seemed to disappear - thankfully it is starting to become an issue again - as the writer above notes it is a big issue - and I guess the line (also above): "The fact that the world population now contains more overweight than malnourished people suggests we're not doing too badly" is humour - dark indeed. It is a shocking and outrageous that the number of those starving is still rising. We have more than enough wealth to share - sadly greed and more gets in the way.
