I was chatting with a senior medic on the train a while ago, when he surprised me by saying that he believed there is consensus in medical opinion that the underlying cause of obesity is not eating more, or even eating junk, but indolence.

After a little googling around, I came up with a BBC quote from the Director of the UK Medical Research Council National Survey of Health and Development to essentially the same effect.  Couple that with the fact that just one in twenty now walk or cycle to school, as opposed to four in five c. 1970), and it’s no surprise that one in seven British children are now obese.

Car culture seems to see people walking as a threat, and cycling as an even bigger one.  It is not unusual to hear abuse from ‘motorists’ or even have things thrown at you through their window as they pass.  I have suffered both, and have even experienced people deliberately driving at me.  Bus drivers in Oxford follow dangerously close as a matter of course.

This is very strange.  I invite explanation.

Of course, within sprawl, you have little or no choice but to drive on every occasion.  Far from the necessary 3,000 steps a day for basic exercise, you will struggle to manage 300.  It’s a curious irony that workaholicism, or simply long working hours imposed upon you, will combine with a car-predicated habitat to deny you the ability to dedicate additional time specifically to exercise.  After sitting in congestion two or more hours a day, and working ten or more, there isn’t any time left.

And so we continue to put on weight, cumulatively.  Until our cardiovascular system says stop.

An interesting footnote is a suggestion that fatter drivers use more gas.  While this is amusing (along with the obvious jocular aside), the effect is small when one accounts for the enormous mass ratio of the typical American car.  In moving from simply overweight into obesity, we increase our mass by about 50%.  But this still represents only around 10% of the total mass, since cars have also gained mass in around the same proportion.  Even if this were not so, the increased bill at the pump would be down in the ‘noise’ — the statistical variation associated with our mileage and vehicle efficiency.

More significant perhaps is the tendency to both use a larger vehicle and to walk less, the fatter we become.  And so, we drive more, and further deter others from walking.

Which, of course, closes the positive feedback loop.

Sprawl in the UK is not quite the same as sprawl in the US.

For one thing, America has plenty of space; they’ve used just 3% of it thus far.  This imparts an ability to survive not just the extra consumption of land, but the pollution and energy drain as well.  In Britain, on the other hand, we’re dependent upon importation of food, since we already have a population twice the size we can feed, and energy, since we have already exhausted our natural resources.  (The one exception is coal, but that would require carbon capture and secure storage — something as yet unproven, and likely to be expensive.)

But there’s another problem : villages and towns are tightly packed on our little island.  Sprawl tends to run roughshod over these, destroying all that was attractive in them.  I witnessed the overrun of my own home village, the arrival of crime and antisocial behaviour, and its complete loss of identity.  Schools, shops, and pubs, closed, while the price of a home rose beyond what I and my brothers could afford, giving the lie to the promise that more houses would mean cheaper houses.  People stopped caring about the place.

And now it’s happening again where I live now.

First, the nearby main road was converted to a four-lane highway, bringing noise and air pollution.  (Light pollution is soon to follow.)  Next, the lanes through the village become rat-runs, with constant traffic, much of it driven too fast and with little care.  Now, we are faced with large housing developments, both between us and the neighbouring town, and within the village itself.  None of it comes near the scale and luxury typical in American sprawl.

Pretty soon, we’ll have the same concrete soulless continuum that dissolved my former home.

A common serious mistake is to associate the origin of suburbia with the private car.  The tram (streetcar) created suburbia.

By the outbreak of the First World War, electric power had replaced the horse for haulage, eliminating (local) pollution and increasing both speed and capacity.  One could live ten miles out of the big ugly city, yet keep your commute reliably under thirty minutes.

A second mistake is condemn suburbia out of hand.  Whether we like it or not, people value privacy, and there’s little of that within a densely populated town or city.

Another problem of urban life, which political correctness denies recognition of nowadays, is crime and antisocial behaviour.  The Victorians always feared the underclasses and counted them carefully.  They believed around 15% of the population were irrevocably irresponsible (e.g. regularly getting drunk), and about 5% were outright criminal.  Who can blame decent folk for choosing to live elsewhere?

Finally, there is access to open countryside, and perhaps a private garden – of particular value when raising children.

Suburbia does not equal sprawl.

Sprawl is characterized by 1) a continuum of housing, unpunctuated by any focus, and 2) access predicated on the private car, with the result that no shared amenity (of any significance) is viable, including high-capacity shared transport, and congestion is inevitable.

A light-rail (transit) station is a focus, and affords an opportunity to get to know your neighbours. Development is then limited by the need to walk (or cycle) there in reasonable time, retaining a boundary around each community.  Rail companies were known to invest in new build themselves, which required pleasant and effective transport to see a return.

The arrival of the car threatened the viability of rail transport (see my page “road versus rail”) but it required both conspiracy and incompetence to destroy it.  While we have plenty of both this side of the ‘pond’, US big business tends to put us in the shade for sheer audacity.

The Pacific Electric Company essentially built Los Angeles, before it was busted by General Motors, which in 1932 formed United Cities Mobile Transit to take over ‘streetcar’ lines and convert them to bus companies.  (It owned Atlantic Greyhound Lines, and made buses.)  In 1936, GM joined with Firestone Tire and Rubber and Standard Oil to form National City Lines, spinning off Pacific City Lines (1938) and American City Lines (1943) to buy up and dismantle electric streetcar systems in more than twenty cities, including Los Angeles.  By 1950, more than a hundred lines had been converted to bus.

As they well knew, buses are not popular – when a rail service closed in Britain in the 1960s, the replacement bus was used by only around one in five of those who formerly used the line.  (See my page on the bus for further comment.)  With the railway gone, all those who could find the money bought a car.

What has changed since then is primarily congestion, the price of fuel (see my earlier post), and both concern and regulation with regard to the environment, both local and global.

Electric propulsion is far more appealing when you can connect the vehicle to a stationary power supply than it is when you have to carry that supply with you (in a battery or fuel cell).  It’s much cheaper, and you can travel as far as you like (the full breadth of France, for example).

Britain and America are waking up to the fact that they are thirty years behind continental western Europe, not just with main line heavy rail, but with light rail too.  The French, who co-led the high-speed rail revolution with their Train à Grande Vitesse (TGV), have shown us how to deliver power to a tram without an ugly overhead cable or a live exposed third rail.

We have come full circle.  The tram (streetcar) is on the way back.

I’ve just finished reading James Howard Kunstler’s The Geography of Nowhere.

There is clearly a much bigger problem on the other side of the pond than in dear old Blighty.

I remember staying in the wonderfully named Hampton Inn (you have to know some English slang) near Tampa.  We tried walking to the nearest restaurant – about 50 yards down the street on the opposite side.  This was rewarded by honking horns and shouts of abuse.  I guess the lack of a pavement (sidewalk) should have given us a clue.

Kunstler’s book was refreshing, in that it reassured me that there are some at least in the US who can see the problem and who want something better.  I found it quite eloquent also : “… the motive force behind suburbia has been the exaltation of privacy and the elimination of the public realm.”

So it was sad to see the same rather snobby, and poorly informed, view of Walt Disney and his creations I’ve come across in other US ‘cognoscenti’.  While it may be true that Americans are “as addicted to illusion … as to cheap petroleum”, I think some forget that DisneyLand and Disney World are designed (mostly) for kids.  Kunstler concedes that, on approaching Disney World, “gone are the hotels, bill-boards, gas stations and other junk”, and that on arriving one finds “a public realm free of autos”.  Sounds good to me.  And he’s just plain wrong when condemning EPCOT (the city Walt would have built had he survived) as Corbusian.  It just isn’t.  There are no towers in which residents are incarcerated, nor is it predicated on the car.  It consists of neighbourhoods, interconnected by a light rail (transit) network, facing common public space.  Car access is there but to the back of each house, as in New Urban design.

Aside from a little too much cynicism, this is a worthy summary of just how much has changed, and why life for ordinary people has got very much harder over the last fifty years.

When he says that “Americans have been living car-centred lives for so long that the collective memory of what used to make <habitat> humanly rewarding has nearly been erased,” I find myself wondering how many Brits there are left who can remember something better than sprawl.  You cannot value what you never have known.
