A new report published by Greenpeace and The Guardian newspaper has highlighted just how much damage is done to children, in particular, by road pollution. Researchers found more than 2,000 schools, of which half were nurseries, close enough to suffer serious health effects.  These include suppression of lung development and asthma. The roads concerned generated illegal levels of pollution.

A Californian study, some years ago, showed that children affected by pollution from a major road were eleven times more likely to develop asthma.

No government agency monitors pollution where children spend time.

No one enforces the law.

Diesel engines cause twenty times more NOx pollution than petrol engines.  Their proliferation is largely responsible for a bad situation growing much worse over the last decade. Manufacturers have been shown to have falsified emissions data, which governments do not verify.

NOx pollution has now been linked to heart disease, cancer and Alzheimer’s disease, as well as asthma, yet nothing is done. All that is proposed is a modest increase in taxes on diesel vehicles, while their numbers and mileage continue to grow. Meanwhile, new major roads are to be built, such as the Oxford-Cambridge ‘expressway’, without any consideration of the additional pollution it will cause.

Our health, and that of our children, matters less to our government than that of the big businesses it truly represents.

Following the scandal over fraudulent emission testing by Volkswagon, the UK Department for Transport (DfT) tested 37 models. None could match their official figures. Realistic road testing showed average emission five times higher.

Despite this, the other arm of government, responsible for certifying vehicles fit for sale in the UK, the Vehicle Certification Agency (VCA), went ahead and approved all of them, using only the recorded laboratory test data.

Clearly, the UK government sees the interests of the car industry as far more important than human health.

It is now firmly established that diesel emissions cause severe human disease, including asthma in children. Our government is granting a license to kill and maim its citizens.  The House of Commons Committee on Environmental Air Pollution puts the annual death rate at 40,000. There is no good way to count the cost of a childhood marred by asthma.

The UK Dept. for Transport published figures this week which show we are continuing the march towards complete gridlock.  In the year to March 2016, the mean delay per mile driven, due to ‘congestion’, increased by 4.2% (4.9% in towns), which means it’s more than doubling every twenty-five years, assuming a linear variation over time.

The trouble is that we should not expect it to be linear, because there are clearly threshold effects. For example, as the traffic rises at a junction, there comes a point where it becomes almost impassable. Once traffic on the main road becomes continuous, there may be no opportunity to turn onto it.

The culmination of the decades-long idiocy of total reliance on road transport is a matter now of everyday experience.  To travel six miles into Oxford by car, the other day, took me an hour and a quarter. That’s less than 5mph. And it was so unpleasant that next time I shall take the bus, which will take an hour and a half. (And the bus service is to be withdrawn, following cuts.)

When the nearby railway was open, the same journey took just thirty minutes, completing the journey on foot, and twenty using a bike. I used to earn £30ph, which is about what I’d save every day using rail and bike. Now multiply that up to account for days worked in a year by the UK population and you save around £120bn. That’s what we spend on the NHS.

1.8% more vehicle-miles were driven, while road-space grew by just 0.1%. Of course, the road lobby has already used these figures to call for more road-building.  Fine perhaps for America, which has ten times as much space per head of population.  In Britain, it would mean bulldozing homes, when we are already very short of those.

In any case, we know that building more roads leads only to more congestion (Downs’ Law in the US, the Lewis-Mogridge position in the UK).

There will never be any substitute for proper planning, of both our built environment and the transport network. A focal pattern, using rail, bike and foot, worked. Road does not. It offers too little capacity and consumes too much space, even if we forgive the pollution, inefficiency and carnage.

Diesel engines were promoted by the UK government as “environmentally friendly”, through a cut in road tax, twenty years ago because they offered a way of reducing carbon emission. However, the same government had already been warned (as early as 1993) that they would cause serious issues for air quality and health.

Diesels may emit about 20% less carbon but they release four times as much NOx, which damages blood vessels, giving rise to stroke, heart disease, diabetes and asthma, and more than twenty times as much benzene-impregnated soot, which causes cancer.

According to the Parliamentary Committee on Environmental Air Pollution (COMEAP), at least twenty-nine thousand people each year die as a result of inhaling polluted air, for which diesel road traffic is primarily responsible. To that we must add the appalling ill health it causes in hundreds of thousands who survive. (When schools in polluted urban areas are compared with others in clean ones, asthma is far less common – good evidence that polluted air does not just promote asthma attacks but causes the disease itself in otherwise healthy children.)

The EU has published mandatory limits on air pollutants but British towns and cities are expected to remain unable to comply for decades.

As an expert said in Channel 4’s Dispatches The Great Car Con (aired on 26th Jan 2015), we are free to avoid contaminated food but not the polluted air we breathe. The worst place to be is inside a car.

More than half of new car sales are now diesels, to add to all the vans, tractors and lorries. In homes and hospitals up and down the land, countless thousands will suffer horribly as a result. Many will die.

Cause of death :  not just the diesel engine, but our massive over-reliance upon road transport.

Snow and ice have descended on Britain for the second time this (2010/11) winter, and the entire transport network has again ground to a halt, except for the railway.

Anyone who has ever read the wonderful Thomas the Tank Engine stories, of the Rev. A. W. Audrey, will know that snow is no obstacle to a train.  Thomas himself only ever became stuck when he refused to wear his snowplough.  There is even less excuse for any modern train to fail in the face of foul weather, of any kind.  Points can be de-iced by electric heaters, and signals can operate by radio.  The only reason why the railway sometimes fails us these days is that drivers will often depend upon the road to get to their depot, because the railway itself now reaches only around half the country, after closure of around a third of the network and the rise of sprawl.

And yet the media, seeking sensation, give equal measure to the 10% failure of rail services as they do to the 90% failure of road transport.  As much time yesterday was devoted to the 20% reduction in international rail services (due to speed reductions) as to the 70% reduction in aviation.

Rail remains the mode of transport by far the most secure against foul weather.  Furthermore, rail is the only mode capable of mass evacuation in an emergency.  If New Orleans had seen the same investment in rail as it had in roads, far fewer people would have suffered and died.  The same high integrity and high capacity that makes this possible also allows movement of the very high numbers attending major cultural events.  The London 2012 Olympics can be served only by major rail investment, which thankfully is going ahead, despite the fact that Britain has been all but bankrupted by its banking industry.

I’m looking out at a road still only safely passable in a four-wheel-drive vehicle four days after a blizzard which deposited ten inches of snow over eight hours, and reduced visibility to a few metres.  All roads here became impassable with an hour, and yet every train ran through our village that day, and within minutes of schedule.

How can we have allowed our entire economy and lifestyle to become almost wholly dependent upon a mode of transport which becomes useless for a full week after a single storm and a temperature just two degrees below zero?

In order to serve their commercial interests the nuclear industry has achieved not one but two triumphs in “public relations” — in other words, lying.  (We should never forget that precisely the same methods were used to get Hitler elected.)

First, it has convinced politicians — and even some fools in the green movement — that nuclear power is essential if we are to reduce greenhouse gas emission, bring global warming under control, and limit climate change.  This is untrue.  Nuclear power is not sustainable since it depends upon a limited natural resource.  Just like oil, nuclear fuel is also widely scattered beneath foreign soil.  The construction of nuclear power stations, and nuclear waste repositories (should anyone ever get around to building them) give rise to immense carbon emission.  Nuclear power also enhances potential terrorism by providing high-value vulnerable targets, and by increasing the risk of the use of nuclear material.  The need to safely store and guard lethal waste for hundreds of thousands of years ought, alone, to rule out any significant exploitation.

Second, it has convinced politicians, and, sadly, the public at large, that nuclear power is safe, and that the Chernobyl disaster was just a one-off accident that really was “no big deal”.  The World Health Organisation believes at least 9,000 died as a direct result.  Greenpeace believes the true figure could eventually reach a quarter of a million.  The fact is, like smoking, it is not possible to attribute any individual cancer to radiation exposure, never mind the source of that radiation.  Nearly 3,000 square kilometres of agricultural land in the vicinity has been lost, and the safe use of vastly more, as far away as Wales, has to be carefully monitored.

Chernobyl was and remains a “big deal”.  Nuclear power is no more safe than it is sustainable, or a solution to climate change.  There is a long history of nuclear accidents, dating back to Windscale in Cumbria in 1957.  The more nuclear power stations we build, the more certain we should be of another Chernobyl.

We can generate enough electricity for our domestic needs, and most of our industrial needs, sustainably. But not enough to power a billion electric cars, making more and longer journeys because our habitat consists almost entirely of car-predicated sprawl.

A final (final) footnote to this story : speed cameras in Oxfordshire are to be turned back on, after it was found (to the surprise of no one with any sense) that drivers had returned to speeding on the roads monitored.

There will be those who claim the difference in speed is low, or that offenders are few, but the fact is that it takes just one car, just a few miles an hour more, to kill a child or main them for life.  It costs nothing to prevent, if fines are levelled accordingly.

For reason and sense to truly prevail, we need more and better automation so that the law can be enforced everywhere, and the assumed right to speed ended for good.

The Cost of the Car was written with reference mainly to Britain, although almost all the arguments presented would apply equally to any part of the rich world.  While I would dearly like to compose a US edition, this is unlikely, given other commitments.  (If anyone out there is interested in doing so then please leave comment below, or get in touch with the publisher.)

I can, however, recommend a report published back in 1992 by the World Resources Institute, named The Going Rate: What it Really Costs to Drive, by James Mackenzie, Roger Dower, and Donald Chen.  If you want the kind of ammunition for the US that my book contains about the UK then it’s here, though now a little dated.

What I find most interesting is that you folk on the other side of the ‘pond’ suffer almost exactly the same blight, with the very same origin, but via a somewhat different route.  In the US, almost infinite space, and absurdly liberal property law, allows sprawl to… well, sprawl… over a vastly greater area.  The combination of distance and congestion results in an unreasonable amount of time spent behind the wheel (consuming energy, emitting carbon, denying more efficient and faster shared transport, etc.).  On this side, it’s just congestion, but to the same effect.

Some things are much worse over there, however.  You are around three times more likely to be killed in, or by, a car.  Granting a driving licence at age 16, rather than 17, together with far wider access to, and need for, a vehicle, comes at a considerable cost.  (Over 40% of teenagers have at least one serious accident.)  You drive approximately twice the mileage driven anywhere in Europe, and you do so in cars that are only half as efficient.  As a result, you are far more dependent upon foreign oil.

While there has recently been some improvement in fuel efficiency (due to a larger proportion of imported cars, and a belated response to increasing gasoline price), the trend in mileage is inexorably upwards (almost doubling every twenty years.)

Aside from chronic congestion, we share the myth that the car represents private transport.  The WRI report contains enough facts and figures to annihilate any such belief regarding the US.  The road network there, as here, has been paid for almost 100% by the State.  Since it’s almost always free at point of use, what can we expect but long queues?

But there is another example here of the same problem via a different route.  In the US, there is always space to build yet another “relief road”, to ease congestion.  If you tried that here, you’d bang right into the neighbouring town (or the sprawl around it).  As I make clear in my book, such roads are no solution.  By Downs’ Law, they will simply induce additional traffic and fill up.  Sadly, this leaves you somewhat deeper in the… mire… and with bloated taxes to boot.

One of the things that has always astonished me is the way so many people can be so two-faced about the market.  Here (and perhaps over there also) farmers would ceremonially hang their family rather than vote anything but Conservative — a party which exists to champion the (unregulated) free market.  And yet they would hang their local MP if he raised the slightest question over agricultural subsidy and bail-out.  Similarly, the road lobby is strongly identified with the same ideology, and yet threatens to shut down the economy almost at the mention of any direct charge for road use.  Yet, without market tolls, there will always be congestion.  It’s a simple matter of supply and demand.

The WRI report includes useful (and frightening) figures for the cost of US congestion, which appear a bit lower than ours, but this may be due to the continuous addition of temporary relief.  If that is so, then it represents merely a transfer from the congestion bill to the tax one.

One red herring is the idea of a fuel tax.  We have that here and it makes not a halfpenny-worth of difference, though it does attribute taxation where it is due, to meet some of the costs of roads and road use.  Accounting for the fact that things are closer together here, we use cars every bit as much with a heavy fuel tax, as you do without one.

The ultimate answer to excessive car and road dependence is to offer people an alternative habitat where they can walk, cycle, or take a tram or train, to make their trips.  As I make clear in my book, this can be offered without denying any freedom to use the car.  It’s about adding liberty, not taking it away.  If there’s one thing we Euros admire about you lot, it’s your love of liberty.  We’re used to rather less of it, and seem to accept any abuse with a shrug.  It’s my hope you guys will show the way.

Of course, you have a problem.  If the road is sacred to the holy car here, it’s quadruply so over there.  (I’m surprised it hasn’t replace that eagle on the bank notes.)

I wish you luck.

A final word concerning speeding, and why it requires control and policing :

The car lobby has campaigned against the very existence of speed limits from its inception (in the UK in 1895 as the Self-Propelled Traffic Association).  In 1930, they succeeded in gaining abolition of the universal 30mph limit.  The casualty rate rose by a quarter over the following two years.  Such a low limit might seem absurd to drivers now used to whipping through residential areas, like my home village, at 45 with almost complete impunity; but, if one truly understands the horror in the potential consequence, and is prepared to question such a constraint rationally, it would surely seem wholly reasonable.

A fool might point out that two thirds of road casualties fall victim within a 30mph limit, and contend that such a limit is therefore worthless.  In fact, such an observation is nothing less than a self-contained argument for a lower limit.

One must first understand that a reduction in speed will always render 1) an accident much less likely, and 2) its consequences much less severe, for three reasons.  First, more time is available to react; but this effect is only linear — the time available is inversely proportional to speed.  The kinetic energy of the vehicle varies non-linearly, as the square of speed — it will more than halve when speed is reduced from 30 to 20mph.  Braking time varies with vehicle kinetic energy, not speed directly; hence, it halves when speed is reduced from 30 to 20mph.

It is the energy imparted by the vehicle that will smash a child’s head.  (If you think this language emotive, you might want to visit any hospital for brain-damaged children.  You will find most have been put there by a car.)  When that little head meets the bonnet of a SUV (at head height), it must absorb all the energy imparted, directly.

After the mindless claim that speed has nothing to do with risk of collision, or its consequences, the second most common claim made by the road lobby is that statistics should demonstrate a clear correlation between speed limitation and casualty rate.  This too is utter nonsense, mainly for all the usual reasons why real scientists avoid reliance upon statistics as far as they possibly can.

First and foremost, they contain information only concerning the domain from which they are derived.  For example, speed cameras were applied to a very small proportion of Britain’s roadway.  Even so, the information gathered at those locations clearly indicated a fall in both accident and casualty rates once they were installed.  However, the claim that one should perceive a rise in those rates nationally, or even across the county, after their removal is nonsense.

Second, statistics are influenced by factors which remain unquantified or which remain entirely unknown; the wider the domain, the more factors there are, and the less specific any prior information concerning them.  One thing we most decidedly do not know, regarding speeding, is just how many people, especially children, are deterred from walking and cycling because of it.  Hence, the claim that we don’t need speed limits because both accident and casualty rate are falling ‘naturally’ is utterly without foundation.  It may simply be that we are removing the people from the risk, not the risk from the people.  There is plenty of evidence that people, especially children, are walking and cycling much less.

Then there is congestion, which is increasingly reducing speed on many routes, and doubtless as a result reducing the accident and casualty rates thereon.  But this doesn’t help stop the youngster being smashed off his bike, or run down while walking to school, by an adult in a car, in a hurry.

One last contention is that there is no evidence that speed limits save lives.  Again, this is utter nonsense.  One study, for the Australian Federal Office of Road Safety, concluded that the risk of becoming a casualty in a road accident doubles with every 5kph above a 60kph limit, where such a limit currently applies.

To avoid rational argument, and hold to a model that justifies personal advantage, while demonstrating intolerance of opposition, is a dictionary definition of bigotry, and is not an acceptable basis for policy in a civilized society.

Intolerance must meet greater intolerance.
