Bastiat’s parking meters
At the Continental Telegraph, Esteban explains why nineteenth century French writer Frédéric Bastiat would be able to fully explain Atlanta’s parking meter woes even though Bastiat never saw an automobile in his life:
One of Frédéric Bastiat’s most famous observations was the importance of recognizing “That which is seen and that which is not seen”. A government agency builds a road, some people get jobs working on the road, voila, look at all the benefits the government has brought us. What is unseen is what would have happened if the government hadn’t taken our resources to build the road, perhaps we would have spent them on something of greater value?
That people often (perhaps usually) overlook the unseen isn’t too surprising, but the inability to see is sometimes striking. A couple of years ago the City of Atlanta decided to get rid of its parking meter enforcement staff and outsource this work to a private sector company (let’s call it NewCo). Some time after the transition there were discussions at the City Council that perhaps they should reverse this decision, or at least find another provider.
What was the source of these complaints? Was NewCo inefficient? Was the City getting less revenue from the meters? No, meter revenues were actually up as were parking ticket revenues. Some misbehavior by NewCo’s employees, bribery, favoritism, kickbacks? No, no, no and no. The problem was that NewCo was doing a better job. Seriously, the City Council was inundated with complaints such as “I was, like, 2 minutes late getting back to my car and they had already ticketed me”. People who had been ticketed as well as many businesses complained about NewCo’s efficiency.
[…]
What really stood out is that no one involved in these discussions – aggrieved parkers or Council members – seemed to think about why we have meters, time limits and tickets. If enforcement is lax, more people overstay their allotted time, one consequence of which is that you have to drive around longer to find a parking space. People notice their parking ticket or the inconvenience of having to run out and feed the meter (that which is seen) but were oblivious to the shortage of parking spaces that is exacerbated by lax enforcement (that which is not seen, or perhaps not identified as connected?).
One wonders how people who live in a City where finding a parking spot is very difficult could “not see” the value of good enforcement. The time spent circling the block, rushing to turn around and grab the space that just opened up before somebody else snagged it, then just missing out and starting the dance over – nobody thought of that? Bueller, anyone?
Emphasis added.

Switching over from internal combustion vehicles to electric won’t be cheap … it really won’t be cheap!
At Spiked, Rob Lyons looks at the British government’s recent decision to ban sales of internal-combustion cars in 2035 rather than the earlier target date of 2040:
First, at present, electric vehicles cost a lot more than those with internal-combustion engines. For example, one car-buying advice website notes that the Peugeot e-208 is as much as £6,200 more than the standard 208 model. There are government subsidies to help with the cost of electric cars (currently £3,500), but can this be sustained if we all switch? It has already been cut from £4,500 in 2018.
That said, while the purchase price of an electric car may be higher, charging is a lot cheaper than fuelling a regular car. Electric vehicles cost between £4 to £6 per 100 miles to charge at home and £8 to £10 using public charge points, while petrol and diesel cars cost £13 to £16 per 100 miles in fuel (although 60 per cent of the fuel cost is tax).
In theory, maintenance should be cheaper, too, given that electric motors have fewer moving parts than petrol or diesel engines. But to further complicate matters, batteries gradually lose their capacity to hold charge over time. They have to be replaced at the cost of thousands of pounds every few years. (The warranties covering battery replacement varies by manufacturer: Tesla, for instance, offers an eight-year warranty, but the Renault Zoe is covered for just three years.)
Electric cars may be cheaper to own overall, but this is largely down to subsidies and tax breaks, including lower vehicle duties and not having to pay charges in low-emission zones. Still, with the entire car industry throwing its efforts into making electric cars cheaper and increasing battery capacity, costs may well come down somewhat, reducing the need for such breaks. Fingers crossed.
The cost to individual owners will be higher, but the costs to build up the electric charging infrastructure will be distributed among all consumers, not just the owners of vehicles:
This brings us to perhaps the biggest problem: where will the power come from and how will it reach us? Eventually shifting all the energy for cars from oil to electricity means producing much more electricity. Greens are pleased that electricity use is currently decreasing, and a greater proportion of electricity is coming from renewable sources. But the arrival of electric cars en masse would demand a whole lot more electricity, mostly to be used at night.
Unless we want to coat the landscape in wind turbines, which are unreliable in any event, we’ll need other sources of power. More nuclear? Fine by me. But will eco-warriors stand for that? Even if we can produce the juice, having lots of cars charging in the same area may overwhelm the local electricity networks. Who is going to pay for the upgrade?
When all of these factors are considered we have to ask if all this effort will really reduce greenhouse-gas emissions anyway. Digging up the resources required to create all those batteries will be hugely carbon-intensive. Perhaps the most likely outcome of banning sales of new petrol and diesel vehicles is that demand for second-hand vehicles will go up. We could end up like Cubans, nursing venerable old cars for years, way beyond their intended lifespans.

QotD: Drinking and driving
I have another brochure on my desk. Actually, I’ve got a lot of stuff on my desk, including possibly a cat or two, but it’s the brochure that’s at the top of the pile. It comes from the Ontario government and it’s called Break The Law Pay The Price. Personally, I’d have put a comma in there somewhere, but the Ontario government laid off the punctuation guy in a cost-cutting drive. (I gather he lasted longer than the water inspection guy.)
According to BTLPTP, “Drinking drivers are responsible for one-quarter of all people killed on Ontario roads.” In other words, only 75 percent of Ontario traffic fatalities are the work of sober people. Either we have more drunks in Ontario or our sober drivers are better drivers than Britain’s. [Where “one in seven of all deaths on the road involve drivers who are over the legal limit.”]
Now, despite the damning evidence in these brochures that sober people are causing carnage on our roads, the people who know what’s good for us are busy trying to lower the legal blood alcohol limit. Early in 2001 the Quebec government announced that it was lowering the limit from eighty milligrams to fifty, throwing in a complete drinking ban for professional drivers — cabbies, bus drivers, and the like. This last measure was a reaction to — well, nothing at all. Were drunk ambulance drivers creating havoc on the roads of Quebec? No. But it gave the government of Quebec the appearance of having taken a strong stand on something. Predictably, the Ontario government immediately made noises about following suit.

QotD: The post-oil-crisis evolution of modern cars
Man I remember back in 1982, we all thought we’d be driving nothing but 3-cylinder diesels by the turn of the millennium. If you went back and told some gearhead in my high school class that in 2017 Dodge would be selling a “street legal” 10-second Hemi Challenger, he’d think you were talking about the 0-60 time of a 4-cyl car.
The computer changed everything. Not only in engine tuning and performance, but in design and modeling.
I had an example of a classic late Dark Ages car, an ’84 Trans Am with the LG4 305c.i. Rochester Quadrabog motor. A hunnert and fifty horsepower and nearly every engine function powered by enough dry-rotting vacuum tubing to reach to the moon and back…
Only a few years later and exotic computer-designed and controlled long-runner port fuel injection systems were common on domestic performance cars and HP numbers were on the right side of 200 for the first time in a decade.
It was coming out of an awful time. Like a friend wrote: When he went into seminary you could buy a Mustang with a nearly 400bhp engine option. When he left seminary, the Mustang was a Pinto.
Being a car enthusiast in America in the latter half of the 70s/first half of the ’80s was like being a dirt farmer in Fifth Century Britain, marveling at the weed-grown roads and disused aqueducts left by a race of giants and building your pig shed with stones looted from a burned library.

More frequent car fires, an unintended consequence of wider adoption of electric vehicles
In Quadrant, Tim Blair recounts the story of a friend crossing the Sydney Harbour Bridge only to find his vehicle was on fire:
Most of us manage to scrape through life with no such flame-related driving incidents. Future motorists, however, may find themselves more frequently enjoying the occasional car-b-que. That’s because electric cars — the things Labor ruinously attempted to force upon us as part of their spectacular 2019 election campaign disaster — seem to be impressively prone to burning.
Now, an ordinary car fire is not really that big a deal. Catch it early enough and it can be quickly dealt with. But a fire involving an electric car is a whole different matter. Those things are like four-wheeled infinity candles.
In the manner of all the money given to its manufacturer by various governments, an electric Tesla recently torched itself in Austria. The Tesla’s fifty-seven-year-old driver had slid off the road and struck a tree, prompting a fire emergency.
In ordinary car blaze cases, a single fire engine or even a personal fire extinguisher is sufficient to deal with the problem. Electric cars, or EVs, demand slightly more attention when combustion occurs. Here’s an online news account:
In order to put out the fire, the street had to be closed and fire authorities had to bring in a container user to cool the vehicle.
Some 11,000 litres of water are needed to finally extinguish a burning Tesla but an average fire engine only carries around 2,000 litres of water.
The container used is said to be suitable for all common electric vehicles. It measures 6.8 metres long, 2.4 metres wide and 1.5 metres high, it is (obviously) waterproof and weighs three tons.
Moreover, “fire brigade spokesman Peter Hölzl warned that the car could still catch fire for up to three days after the initial fire”.
I’ve owned one or two cars that were sensibly equipped with fire extinguishers. Future motorists may wish to tow around a lake, just in case their earth-friendly electric cars decide to go the full kaboom.

“Clean” alternative energy sources are not free … in fact, they’re quite expensive
Earlier this month in Foreign Policy, Jason Hickel wrote about the requirements for expanding current renewable energy generation (wind and solar):
The phrase “clean energy” normally conjures up happy, innocent images of warm sunshine and fresh wind. But while sunshine and wind is obviously clean, the infrastructure we need to capture it is not. Far from it. The transition to renewables is going to require a dramatic increase in the extraction of metals and rare-earth minerals, with real ecological and social costs.
We need a rapid transition to renewables, yes — but scientists warn that we can’t keep growing energy use at existing rates. No energy is innocent. The only truly clean energy is less energy.
In 2017, the World Bank released a little-noticed report that offered the first comprehensive look at this question. It models the increase in material extraction that would be required to build enough solar and wind utilities to produce an annual output of about 7 terawatts of electricity by 2050. That’s enough to power roughly half of the global economy. By doubling the World Bank figures, we can estimate what it will take to get all the way to zero emissions — and the results are staggering: 34 million metric tons of copper, 40 million tons of lead, 50 million tons of zinc, 162 million tons of aluminum, and no less than 4.8 billion tons of iron.
In some cases, the transition to renewables will require a massive increase over existing levels of extraction. For neodymium — an essential element in wind turbines — extraction will need to rise by nearly 35 percent over current levels. Higher-end estimates reported by the World Bank suggest it could double.
The same is true of silver, which is critical to solar panels. Silver extraction will go up 38 percent and perhaps as much as 105 percent. Demand for indium, also essential to solar technology, will more than triple and could end up skyrocketing by 920 percent.
And then there are all the batteries we’re going to need for power storage. To keep energy flowing when the sun isn’t shining and the wind isn’t blowing will require enormous batteries at the grid level. This means 40 million tons of lithium — an eye-watering 2,700 percent increase over current levels of extraction.
That’s just for electricity. We also need to think about vehicles. This year, a group of leading British scientists submitted a letter to the U.K. Committee on Climate Change outlining their concerns about the ecological impact of electric cars. They agree, of course, that we need to end the sale and use of combustion engines. But they pointed out that unless consumption habits change, replacing the world’s projected fleet of 2 billion vehicles is going to require an explosive increase in mining: Global annual extraction of neodymium and dysprosium will go up by another 70 percent, annual extraction of copper will need to more than double, and cobalt will need to increase by a factor of almost four — all for the entire period from now to 2050.
Wind turbines require a lot of concrete to stabilize them on site (hundreds of tons of it), and that concrete is very carbon-intensive to create in the first place (nearly 930 Kg of CO2 per 1,000 Kg of cement), but even those huge turbine blades have a limited working lifespan and can’t be easily recycled into anything economically, so they generally end up in landfills.

EFF sues Homeland Security over illegal GPS vehicle trackers
Kieren McCarthy on a recent lawsuit by the Electronic Frontiers Foundation:
The Electronic Frontier Foundation (EFF) has sued the US Department of Homeland Security to find out more about a program where, it is claimed, officers secretly stick GPS trackers on vehicles they are suspicious of as they come through the border.
The EFF has made repeated freedom of information act (FoIA) requests about the program’s policies but has been stonewalled, with Homeland Security’s responses claiming any information would contain “sensitive information” that could lead to “circumvention of the law.”
The foundation’s main concern is that Homeland Security is carrying out its secret tracking without a warrant, or even anything beyond a single officer’s suspicion. And it points to a recent US Supreme Court decision where it ruled that warrantless GPS tracking was unconstitutional under the Fourth Amendment.
Details of the program came to light last year when customs officers revealed in court filings that they had used GPS trackers without a warrant at the border. Since then the EFF has tried to find out what the policies and procedures are for deciding when a vehicle can be tagged. The relevant authorities have not been keen to go into any detail.
There’s another legal precedent too: a California court ruled that government officials’ use of GPS devices to track two suspected drug dealers without getting a warrant violated the Supreme Court decision, made in 2012, and was government misconduct.

1950s Willys Jeep Promotional Film – The Jeep Family Of 4 Wheel Drive Vehicles
PeriscopeFilm II
Published on 3 Sep 2015Willys, the “World’s Largest Manufacturer of Utility Vehicles,” presents the Jeep Family of 4-Wheel Drive Vehicles and Special Equipment, a circa 1954 black-and-white film promoting Jeeps produced for civilian use. Following the success of Jeeps during World War II, the film opens with an explanation of how the vehicles soon their way to civilian use. Some of the vehicles seen in this film are used by construction companies, farmers, firefighters, and even at airports to tow aircraft and move cargo trailers and plow snow. At mark 02:49 the film introduces other types of Jeep equipment, such as a generator that turns the vehicle “into a mobile source of electric power to operate saws, communication equipment, motion picture equipment, flood and spotlights. And indeed any electrical equipment that must be moved around over bad terrain or in bad weather.” Scenes also capture telephone company repair crews, oil field crews, plus local and state road crews and construction companies. A Jeep is shown at a cemetery at mark 04:03 moving sand, shrubs, and burial equipment around the grounds in addition to lifting memorial markers. The viewer learns about variable engine speeds beginning at mark 05:55 with an up-close look at an engine and a discussion of its power, as well as various ways that power can be tapped for various operations. As it continues the film touts the Jeep rotary cutter (mark 07:45) as high brush is cut down, a hammer mill (mark 08:15), and a trencher (mark 08:30). There are forklift attachments, front and rear winches, as a front winch is shown pulling a dead tree from the ground (mark 10:10). The sales pitch rolls on at mark 11:42 showing some Jeep steel tops including the half-cab, master, and standard top — “each one designed for a special purpose but all three designed to stand up in rough hard service year after year.” Mark 12:00 begins an explanation of the vehicle’s 4-wheel drive capabilities, meaning that the vehicle “can go anywhere to do its job” including remote camping and hunting spots, while by mark 13:48 there’s a look at a Willys sedan delivery vehicle as grocery store employees are shown loading items into the back, and the Willys pick-up trick at mark 14:52. Other models are shown hauling grain and livestock, as well as an ambulance (mark 17:00).
Jeep is a brand of American automobiles that is a division of FCA US LLC (formerly Chrysler Group, LLC), a wholly owned subsidiary of Fiat Chrysler Automobiles. The original Jeep was the prototype Bantam BRC. Willys MB Jeeps went into production in 1941 specifically for the military, arguably making them the oldest four-wheel drive mass-production vehicles now known as SUVs. The Jeep became the primary light 4-wheel-drive vehicle of the United States Army and the Allies during World War II, as well as the postwar period. The term became common worldwide in the wake of the war. The first civilian models were produced in 1945. It inspired a number of other light utility vehicles, such as the Land Rover. Many Jeep variants serving similar military and civilian roles have since been designed in other nations. Willys-Overland and Ford, under the direction of Charles E. Sorensen (Vice-President of Ford during World War II), produced about 640,000 Jeeps towards the war effort, which accounted for approximately 18% of all the wheeled military vehicles built in the U.S. during the war.
From 1945 onwards, Willys took its four-wheel drive vehicle to the public with its CJ (Civilian Jeep) versions, making these the first mass-produced 4×4 civilian vehicles. In 1948, the U.S. Federal Trade Commission agreed with American Bantam that the idea of creating the Jeep was originated and developed by American Bantam in collaboration with some U.S. Army officers. The commission forbade Willys from claiming, directly or by implication, that it had created or designed the Jeep, and allowed it only to claim that it contributed to the development of the vehicle. However, American Bantam went bankrupt by 1950, and Willys was granted the “Jeep” trademark in 1950.

My secret for buying woodworking tools DIRT CHEAP
Rex Krueger
Published on 16 Oct 2017More videos and exclusive content: http://www.patreon.com/rexkrueger
My trick for buying good tools at super-low prices is really simple: go to antique car and antique tractor flea markets. These places are mostly filled with car parts, but when a vendor does have woodworking tools, he’s usually looking to unload them as fast as possible. Often, car guys don’t even know what they have, so woodworkers can score loads of useful or collectible tools for pocket-change. These flea markets are also a great source of consumables like glue, thinners, brushes, and sand-paper. You can stock up on the most expensive stuff for cheap.
