Self-driving cars could transform land transport

In the UK the talk is about taxpayers paying for an extensive high speed railway network between London, Birmingham, Manchester and Leeds.  It would cost £35 billion to build and would lose money.   It will mostly service well-heeled business people (the fares will be too high for families, who will drive, or the poorer, who will take the multiple competing privately provided coach services).  90% of its users will be those using trains now, or people who wouldn't have travelled in the first place.  It will make next to no impact on domestic flights or road traffic.  One of the main objectives is to free capacity on the existing lines, so that more loss making commuter services can operate on the lines close to London.

In Auckland the talk is about an underground rail loop to enable its commuter rail service, soon to be electrified, to have more capacity during the peak hours.  Roughly 45,000 trips a day are taken on that system, roughly the entire average daily trips of Fenchurch Street station in London (yep that busy) (and 10% less than Wellington's network, despite Wellington's region having at least a quarter of Auckland's population.  It would cost NZ$2 billion to build and would lose money.  

In both cases the projects are expensive, not financially viable, and serve relatively few people.

They are 20th century solutions to perceived transport problems, but another is on its way, and it could transform land transport between and within cities.

Self-driving cars. Allister Heath says it makes big rail schemes like HS2 outdated.

The technology exists now.  Cars can already park themselves, emergency brake, follow road lines and follow other vehicles and brake automatically.  Several US states are already changing laws to allow for fully autonomous road vehicles, and the technology now being trialled enables vehicles to navigate safely along existing roads.

What could that mean?

Road vehicles that actively avoid collisions, both with other vehicles, and cyclists and pedestrians.

Road vehicles that operate in convoys, in close formation on major roads, increasing the capacity of those roads by a factor of three to four, rivalling railways.

Road vehicles that don't need a driver, that can be sent to be parked anywhere, called up on command by mobile phone.

Motorways that operate like trains of vehicles, except that the vehicles have the ultimate flexibility of starting and ending trips anywhere on the road network.

Traffic lights will no longer need to keep traffic stopped, but rather interweave traffic to maximise capacity.

Speeds can be faster where it is safe to do so, and better managed where there are many pedestrians.

Cars could be parked with a far higher density.

Let's not pretend there are barriers to this.

Technology needs to be refined, it needs to be secure.  Nobody wants autonomous cars diverting onto footpaths and mowing people down.

Laws need to be changed, so that owners of vehicles are liable for accidents when there is no driver or active driver.

Roads need to be better managed, so lines are maintained, databases about road rules, traffic signals adapted and systems in place so the network is actively managed.   

However, it can transform transport.

Buses can have the capacity of commuter railways (with the exception of high frequency metro services, which Auckland will never have).

Roads can have much more capacity, so there is far less need to build more capacity, and there is far less need to build safety into the roads with barriers and signs and speed limits that reflect driver behaviour.  

Roads would be so much safer that incidents of accidents causing congestion would be rare, and thousands of lives would be saved from serious injuries, and hundreds of millions of dollars of property damage and health costs avoided.

Vehicles would be much more fuel efficient, as vehicles become more efficient anyway, reducing emissions and the environmental impacts from transport.

Roads would be more like networks akin to telecommunications and energy networks, and politicians choosing projects to expand capacity would be rightly treated as amateur fools.  Who today would listen to a politician who says that a specific switch needs to be installed on a network, or a substation or that cable capacity be added somewhere?

Railways are bespoke inflexible networks that have a lot of capacity best suited for a narrow range of transport tasks.  The range of those tasks will narrow even more with automated road transport.

Of course some will still choose to drive, and will have options to do so, for leisure, but probably pay much more for insurance to do so without driving assistance.   What happens ought to be up to market demand, for vehicles and for roads.

Unfortunately, roads are managed by politicians and bureaucrats.  If anything is going to get in the way of setting them free, it will be them.

Looking for innovation? Try a bureaucracy

Innovators, creators, producers, inventors.   Think of the greatest leaps forward in modern history that have changed economies and how people lived.  Think how many were spearheaded by a government bureaucracy.  Think how many benefited from being in a high tax economy.  Then read this from Wayne Mapp, a man who knows about innovation with his extensive entrepreneurial and  military and political background:

The Government is backing innovation to drive New Zealand’s economy forward and raise New Zealanders’ standard of living... Prime Minister John Key today launched the new Ministry of Science and Innovation (MSI)

Think of every single technological innovation in the last 30 years, do you really think there would be more if there had been the MSI?  

What else could government do?

How about get out of the way?  How about cutting company tax to 10%, so that businesses that do want to engage in research, development and be cutting edge about technology have an environment when they don't see the state taking a third of the "winnings"?

How about opening up the education sector so schools and universities are not dominated by a centrally planned bureaucratically specified curriculum, but that parents can withdraw their children from state schools and take their taxpayer funding with them to free private schools?  In other words, let innovators get involved in educating future innovators, not schools dominated by sclerotic unionists whose main philosophy is a burning envy of distrust of business and a politically driven view of the environment and humanity's relationship with it.

How about saying openly and loudly that you don't know what's best and you can't hire bureaucratics who can pick winners either?  You would be telling the truth, you'd be confronting the myth perpetuated by the left and most other parties that they can magically rescue the economy and advance it by spending other people's money on bureaucratically assessed beneficiaries.

However, it is clear National is of the left, given it's interest in growing the state.  So why vote for more of the same this year?

Green MP uses abuse rather than debate

What happens when you challenge the co-leader of the Green Party in one of his blog posts?

He resorts to name calling.

Take this thread, where Russel Norman gets hysterical about cellphone towers, with scaremongering about them being near children's bedrooms etc.

The bogey is non-ionising radiation, and of course the Greens have decided the target on this one are cellphone towers which are commissioned by another bogey - evil privately owned telecommunications corporations (oh if only it was the Post Office, we'd still be testing to see if cellphones are safe or we'd have our own bespoke system with no roaming to rip people off when overseas).   Russel even claims the group of bureaucrats and industry representatives involved in setting standards for such things was:

another committee dominated by industry and government departments with one health professional. A group dominated by those trying to reduce costs for telcos.

So a conspiracy of those who don't believe the pseudo-science. Playing the ball not the people again.   If these people don't take it seriously then it must be vested interest, rather than being wrong.

Now let's be clear.  I do think there can be issues with continuous high concentrations of non-ionising radiation from sources like cellphones or laptops.   There is some evidence around very high volumes of cellphone use and effects on tissues that frankly tell me just to be cautious.  However it is about handsets NOT transmitter towers.

Why?  Well humanity has been testing non-ionising radio transmitters since the 1920s, and at transmission power many many many times that of any cellphone tower.  West Auckland has been bathed in high powered TV transmissions from Waiatarua since the 1960s, as has Khandallah and Johnsonville in Wellington from Kaukau.

So I wrote:

Suggest you shut down the AM transmitters for National Radio, the AM Network and Newstalk ZB in Titahi Bay since they have been transmitting non-ionising radiation blanketing Porirua City at levels of over 100x the strength of cellphone transmitters since the 1940s. Mt Victoria has had radio transmitters on it for some years as well, and then Khandallah and Johnsonville have had nearly 50 years of Kaukau blanketing them. 

I have a friend who was part of a detailed study into levels of non-ionising radiation in Australia. A group of unscientific cellphone site phobics demanded readings be made in one town, and it was found the local TV transmitter on the hill exposed residents to much more continuous exposure at higher volumes than those who would live within a radius of the cellsite. She told them the TV transmitter and local FM radio stations would need to be closed first before removing cellsites – naturally there was an outrage and people couldn’t stand losing TV and radio.

However, don’t let science and the fact that human beings have been bombarding each other with high levels of non-ionising radiation for a couple of generations get in the way of renewing scaremongering over something that hasn’t been remotely demonstrated to be dangerous to human health. Don’t confuse it with the issue of cellphone handset exposure to brains, which does have some merit as an issue (as people haven’t been doing that).

I’m amazed you haven’t jumped on cordless phones at the home, wifi base stations at home, electric blankets (sleeping on an electrical element), the people sitting in front of cathode ray tubes for the last couple of generations (LCD, Plasma and LEDs are ending this). How many of the people who you’ve scaremongered about cellphone towers happily have any number of these devices and let their kids use them and don’t think twice about it? 

Or is this really about beating up privately owned telcos instead of a balanced rational debate about science? Otherwise you would have long campaigned for National Radio’s 500kW transmitter at Titahi Bay to be shut down years ago.
 
However, that doesn't matter to Russel.  He doesn't want to tell people to turn off the radio stations or TV.  It's a war against corporations as you can see by his response to me here:
I’m interested that a blogger called Liberty Scott seems to have so little concern with freedom. The state ties people’s hands over the control of cellphone towers so they can’t resist telcos and you applaud – rather typical Act Party position – freedom for corporations and no rights for individuals. CaptivityScott might think that the people are illinformed to be concerned about a cellphone mast outside their kids bedroom, but genuinely freedom loving people would defend their right to tell the state and corporations to move away, as the courts have done in france.

Kadin, bj and Kerry, there are of course many other sources of non-ionising radiation already present. The question is should we be concerned at adding to the increasing background level. We are doing it with wifi quite extensively at the moment. And there are studies raising issues around it. I say keep an open mind.

So he lazily associates me with ACT, and then starts engaging in childish name calling, then claims to want "the state to move away", which of course is the antithesis of his politics.   He then admits there are other sources, but that it is about adding to the background level.   This is scientific hogwash.  The issue, if there is one, is not lots of radio signals on different frequencies, but intense application of one continuous transmission over a long period. 

Sue Kedgley then lifts it to her usual heights of calm reasoning by claiming conspiracy.  Even Radio NZ must  be in on it:

The whole saga is a classic example of vested interests manipulating the policy process in Parliament. The media are also complicit. When the Green party tried to alert people to the so-called National Environmental Standard, and its effects, the media completely ignored it. Only the Wellingtonian reported on it. Could this have anything to do with the massive advertising by our telecommunications companies?

Didn't occur to her that most people don't believe the scaremongering and that being ignored can simply mean people have rolled their eyes and decided they have better things to worry about.
 
Without me responding, Russel plays the man not the ball again:
 It seems that you and DungeonScott are very proactive talking about freedom except when the rubber hits the road you are all in favour of restricting people’s rights and increasing corporate rights. the freedom you are after is the antithesis of human freedom, it is corporate freedom.
Well done Russel, you refuse to consider the issue on its merits.  You have hitched yourself to a bandwagon embraced by all sorts of snake-oil merchants because it suits your big company bashing agenda.  You can't actually answer the counter-claims about non-ionising radiation partly because you know nothing about it, but also you don't appear to have the humility to admit you (and Sue Kedgley, chief scaremongerer) are wrong.

What the Green Movement Got Wrong

A documentary with this very title is to be broadcast on Channel 4 in the UK this Thursday.  This article in the Daily Telegraph summarises the key point of the broadcast - that environmentalists were wrong to oppose nuclear power and genetically modified crops.

American activist Stewart Brand said "Environmentalists did harm by being ignorant and ideological and unwilling to change their mind based on actual evidence. As a result we have done harm and I regret it."

None of this is news to me, since identifying the ideological rather than the evidential behind environmentalist claims is rather easy.  Jeanette Fitzsimons, the former Green MP, was a master at this, claiming 1999 was the last Christmas to enjoy potatoes "you could trust".   One of the reasons minds have been changed on GM foods for example, is because people have been eating them for over a decade, without a shred of evidence of any ill health effects.

However, beyond that documentary one of the latest scientific breakthroughs will help put paid to the myth that new roads shouldn't be built, because the "inevitable" end of cheap oil will mean private motoring will be too expensive for most people.

According to Geek.com, DBM Energy, a manufacturer of batteries for forklifts, decided to trial its rechargeable battery in a car.  An Audi A2.  The result?  A battery cheaper than existing Lithium Ion technology in cars, with a range of 375 miles (603 kms), averaging at 55 mph (89 km/h) on a charge of 6 minutes.  Now obviously there are a few steps to take before this becomes mass production, but a future of rechargeable cars might just have moved a little closer.
