    The move to the suburbs and mass adoption of the car took place in only a decade or two, post WWII. It might take 20 years to turn around, but not doing so will fuck the planet for ever.

    The best way to get people onto bikes is to create the equivalent of bike freeways that cyclists can travel along without any cars. This can be very cheaply done by putting a bike lane next to a river. The river running East-West in the city of Adelaide has this path, and every year or so the local paper has people from 5/10/15km out from the CBD leave home by car or ride along the river and every time the bikes win.

    http://maps.google.com/maps?f=q&hl=en&q=adelaide&i e=UTF8&z=13&ll=-34.921267,138.599396&spn=0.095993, 0.21698&om=1

    A grid of these bike-only paths (requiring only a 2m wide concrete path) at reasonable spacings across the city (so that say, someone only has to ride a max of 2-3km on the road) would make cycling safer, less polluting and quicker than car travel.

    The only trouble is, until bike shops and sports-energy-bar manufacturers give more cash to politicians than oil & car manufacturers, this will be vigorously resisted.

    >> Riding a bike and getting hit by a car is far more deadly than getting hit by a car while driving a car.

    Cars kill 1 million a year in accidents and 1.5 million a year in air pollution (cars make up 50% of pollution which kills 3M globally)

    Everyone riding bikes would cause FAR FAR less deaths, but the trouble is, if everyone does the right thing, the defectors (in game theory terms) who do the "wrong" thing get the payoff in personal safety. By driving a car for safety you gain personally, at the expense of everyone else.

    >> Parking isn't a problem if you live someplace that has plenty of parking.

    >> Expensive to society as a whole? Probably, but that's the choice we've made, and now we have to live with it.

    Here you are expousing a horrible idea that seems to have gained mind-share (especially in politics): If you make a bad decision, don't admit or try and fix it but instead keep going down the wrong path as to change requires effort or to admit a past mistake.

    We can be better than this.

    It seems that the parent poster generalised, assuming he was talking to someone who lived in an urban area. You are one of the small percentage that doesn't, so it doesn't apply to you.

    >> Walking or cycling short distances (a few miles or less) isn't exercise unless you weigh 300 pounds.

    Are you joking? You can ride pretty easily on a bike, but it takes a lot more human exertion than pushing accelarate/brake and turning a wheel.

    Other reasons: People become more invested in the status quo as they become older, and thus become more conservative.

    Babyboomers make up a significant proportion of the population. Thus, when they were young, they were listened to, and lots of changes (equality of women/non-white etc) occured. Now that they are old, almost all countries in the English speaking (winners of WW2) world have become very conservative.

    Evolution occurs when a new generation replaces the old. A society where the old outnumber the young will not evolve.

    In the western world old people are sitting in their big houses with backyards while young families with children are crowded into small apartments.

    Once the old people can no longer look after themselves, they will be put into a care home, and kept alive for decades using modern technology. I visited old folks homes for a while, and me playing chess with an old man for 1 hour a week was the highlight of his life, the highlight for another man was me rolling a ball back and forth on a table to his arthritic hands - it made me incredibly depressed.

    It seems that living longer, no matter at what quality of life, is regarded unquestioningly as a good thing. People can and do suffer when they are old, and if they want to die, the state will not allow them that choice.

    Old person: "I don't want to live, I am in immense pain"
    Government: "You are not allowed to end your suffering, we will force you to stay alive and in pain"

    Keeping people alive has a cost. Every old person living in a semi-comatose state in a nursing home has costs to the person, the country and the world, the same amount of money could probably save 5-10 dying children in a developing country.

    All I'm saying is, maybe we should think about quality of life rather than quantity.

  18. Re:The market will drive it... on The Segway, Five Years Later · · Score: 1

    I understand that current decisions make sense given current economic conditions.

    Given the current real estate bubble, and the still low price of gas (sure people complain over there, but it is still very cheap, far cheaper than the "true cost" in terms of pollution, infrastructure and war) it is cheaper to drive a 1 tonne car for 30 minutes rather than live closer to work.

    However, factors are likely to change and so communities should be constructed so that they are viable for hundreds of years, instead of the 5-10 years that most developers and people think ahead.

    Have you ever been to Europe? Some cities are shitholes, but some still have the same streets that were designed for animal/human powered traffic and the communities are wonderful.

    My inner city cottage in a 1 million person Australian city was built before cars, and I can get to work and the shops (bank/video/pub/2 grocery stores within 200m) without owning a car. The rest of my city however, has massive urban sprawl much like many US cities. I worry that people's desire for lifestyle is trumping long term thinking. It has always been like this, though - silly humans!

    It seems that your lifestyle is only sustainable given extremely cheap energy. Maybe you should think about moving closer to where you work and useful services (or telecommuting) rather than waiting for technology to maintain your outrageous transportation demands.
