The Electric Vehicle Mileage Fraud Update: Singapore Figures It Out

Long-time readers know that while I have no particular problems with electric cars, I do think that the EPA uses fraudulent standards for evaluating the equivalent fuel economy or MPGe of electric vehicles.  In short, the current Obama standard ignores the previous Clinton-era methodology and creates a crazy new standard that assumes fossil fuels are burned with perfect efficiency when making electricity.  Most of my readers (but perhaps few Obama voters) will understand this assumption to be absurd.  The result is, as discussed here in Forbes, that the current MPGe numbers for electric vehicles are overstated by a factor of 3 (specifically you need to multiply them by 36.5% to get the correct equivalent amount of fossil fuels that must be burned in the power plant to power the electric car).  When this correction is made, cars like the Nissan Leaf are good (but not as good as a Prius) and cars like the old Fiskers Karma get worse mileage than a SUV.

As I wrote in the article on the Karma,

...electric vehicle makers want to pretend that the electricity to charge the car comes from magic sparkle ponies sprinkling pixie dust rather than burning fossil fuels. Take this quote, for example:

a Karma driver with a 40-mile commute who starts each day with a full battery charge will only need to visit the gas station about every 1,000 miles and would use just 9 gallons of gasoline per month.

This is true as far as it goes, but glosses over the fact that someone is still pouring fossil fuels into a tank somewhere to make that electricity.  This seems more a car to hide the fact that fossil fuels are being burned than one designed to actually reduce fossil fuel use.  Given the marketing pitch here that relies on the unseen vs. the seen, maybe we should rename it the Fisker Bastiat.

Well, congrats to Singapore.   They seem to have figured out what the US hasn't :

In the United States, motorists who buy a new Tesla Model S are eligible for an array of federal and local tax breaks because the all-electric sedan is considered a zero-emissions car. The story is different in Singapore, however, where the nation’s first Model S owner just found out his car is subject to heavy taxes because it’s lumped in the same category as some of the dirtiest new cars on the market.

Joe Nguyen explains he spent seven months trying to import a Model S that he bought in Hong Kong to his home in Singapore. The government’s Carbon Emissions-based Vehicle Scheme (CEVS) rewards motorists who import a used eco-friendly car with a roughly $11,000 tax break, but Nguyen was slapped with an $11,000 fine based on the conclusion that the S uses too much electricity.

“I don’t get it, there are no emissions. Then they send out the results from VICOM, stating that the car was consuming 444 watt hours per kilometer. These are not specs that I have seen on Tesla’s website, or anywhere else for that matter,” explained Nguyen in an interview with Channel NewsAsia.

A spokesperson for Singapore’s Land Transport Authority (LTA) said the fine is fair and completely justified.

“As for all electric vehicles, a grid emission factor of 0.5 g CO2/Wh was also applied to the electric energy consumption. This is to account for CO2 emissions during the electricity generation process, even if there are no tail-pipe emissions,” wrote the spokesperson in a statement. The LTA added that it had never tested a Model S before it received Nguyen’s car.

That means that, under Singaporean regulations, the Model S falls in the same emissions category as cars with an internal combustion engine that emits between 216 and 230 grams of CO2 per kilometer. In other words, it’s about as eco-friendly a high-performance, gasoline-burning models like the Audi RS 7, the Mercedes-AMG GT S, and the Porsche Cayenne S.

Actually, the US DOE does in fact publish electricity usage in watts per mileage driven.   They list numbers in the range of 38 KwH per 100 miles for the Model S, which would be about 238 watt hours per kilometer, so such numbers exist though Singapore thinks the car is less efficient than does Obama's DOE.  By my calculation the true MPGe (if the DOE's electric efficiency numbers are trustworty) of the car should be around 32, which is good for a large performance car (and well better than the competitive cars cited) but probably not lofty enough to deserve a subsidy.  Singapore's calculations that the Model S is as dirty as these cars on a CO2 emissions basis may still be correct even if it is more efficient if most of Singapore's electricity is produced by coal.

Google Fi Review, and (Finally!) International Roaming Rates May be Set to Drop

For years I have been frustrated with the costs of trying to take my cell phone on international travel.  Yes, one can buy cheap sim cards locally, but you obviously lose access to your domestic phone number for the duration (leaving aside dual-sim phones and some tricky and expensive forwarding tricks).  If you wanted to keep your phone number so people can still reach you on the number they already know, you were in for some crazy roaming charges -- particularly on data.  I use Verizon (mainly because my business takes me to out of the way places where Verizon is the last available carrier) but until recently their international rates were awful, charging one 50 cents per text and $25 per 100mb of data in addition to a $25 a month international plan fee.

I use a lot of data when overseas and outside my hotel room, so I really wanted a cheaper data plan  (Google maps is a lifesaver when one is walking streets with signs all written in Thai).  My go-to solution in the past was to have a T-Mobile account I turned on and off on an unlocked phone (an old Nexus 5).  T-mobile has plans that allow unlimited text and data without roaming charges in most countries, and it is still a good international solution, though I met with a few technical irritants in some of the countries I have visited.

A while back, I accidentally killed my old Nexus 5 and bought a new Nexus 5x with the intention of swapping in my T-mobile sim card from the old phone.  However, I saw an article that said the Nexus 5x was one of the couple of phones that would work with the new Google Fi service, so I signed up to try that.  $20 a month unlimited domestic calls and text and unlimited international texts.  Pretty cheap international calling rates and the phone defaults to calling by wifi if possible to save any charges.  Data at $10 per 1GB anywhere in the world, with any unused data credited at the end of the month (so the $10 is pro rated if you use less, essentially).

I used the phone in Thailand, Singapore, and Hong Kong, and not just in large cities -- we got out in the smaller cities well away from the tourist areas of Thailand.   Service was flawless everywhere with one exception (discussed in a minute).  Wifi calling worked fine and I had a good signal everywhere, even in smaller towns.  Charges were exactly as promised.  It was a very impressive service.  It uses the T-mobile network in most places, so I am a little reluctant to make it my full-time service because when I tested T-mobile several years ago, it just didn't reach far enough to the out-of-the way domestic locations I visit, but I plan to try again.  I would really love to be on this service rather than Verizon and believe it would save me a lot of money.

I only had two problems with it.  The minor problem was that I had some issues with wifi calling disconnects in one hotel, though this could easily have been due to the notoriously low-bandwidth of many hotel wifi systems**.  Switching off wifi and making a regular cell call worked fine.  Google says that the service automatically chooses between wifi and cellular based on bandwidth and conditions, but it may be this algorithm needs more work.

The more irritating problem was that the phone would simply not get a cellular data connection in Hong Kong.  I contacted Google service (this was a great process that involved sending them a message and them calling me back immediately, a better process in my mind when travelling internationally).  After some fiddling around, the service agent checked came back to me to say, "known problem in Hong Kong with internet access.  You will need to buy a local sim card.  We know this is a hassle, so we just credited your bill $20 to offset the cost."  It would have been better to not have this hassle -- I was switching sim cards every night to see if I had any texts at my domestic number -- but I thought they dealt with it as well as possible, and they were a hell of a lot more helpful than T-mobile was when I had an international roaming issue with them.

Under the T-mobile and Google Fi pressure (which really means due to T-mobile, since Google Fi is largely possible because of T-mobile), I am starting to see cracks in the pricing of Verizon.   They seem to have a new plan that allows one to keep their domestic data, text, and voice pricing and allowances while roaming internationally for a $10 a day charge.  This is still more expensive than T-Mobile and Google Fi but literally an order of magnitude, and maybe two, cheaper than what they were offering for international travel a year ago.

**Footnote:  I have way more sympathy for hotels and their wifi systems.  We installed a wifi system in a 100 site campground in Alabama.  That system has become a data black hole -- no matter how much bandwidth I invest in, people use more.  Every night it seems like there are 300 people on 100 campsites all trying to stream a movie in HD.  I am not sure it will ever enough, and we get no end of speed complaints despite having an absurd T1 bandwidth into the system.  I can't see myself ever investing in such a system again.

Postscript:  It is a good habit to point out data that is inconsistent with one's hypotheses.  I am incredibly skeptical of US anti-trust law, particularly since it seems to have morphed into protecting politically-connected competitors (e.g. cases against Microsoft and Google) vs. protecting consumer choice.  I will say though that the killing of the acquisition of T-mobile by AT&T seems to be a godsend for consumers in the cell phone business, as T-mobile has become a hugely disruptive force generally benefiting consumers.

Shock of the New

Jackalope Pursuivant takes off from my post yesterday about Pearl Harbor.  If I were to give it a theme, I would call it "shock of the new."  From time to time folks, for example in the military, may say that they understand a new technology, but the fact that a few smart staff officers "get it" does not mean that the military has really adjusted itself to it.  Like any large organization, it has a culture and set of expectations and people who have been successful based on the old model of things.   They may say they understand that naval aviation has changed things, but they don't really adjust themselves until Pearl Harbor and Clark Field and Guam and Singapore are full of smoking ruins of planes and ships.

Dan's observation about how quickly the US dusted itself off and recognized that the world had changed is a good one.  One could argue that no one did this in WWI.  The Europeans had every chance to see what the machine gun could do even before the war in a few African wars.  Heck, the final year of the American Civil War around Petersberg was a preview of WWI, as was the ill-fated charge of the light brigade.  But armies were still dominated by cavalries and plumed hats and bayonet charges and elan vital. Even in 1916 and 1917, when they should have learned their lesson, commanders were still obsessed with making full frontal charges.  The Americans had the chance to watch the war for four years before they entered, and then promptly began committing the exact same mistakes based on the exact same faulty assumptions as in 1914.  (Neal Stephenson has a great take on American flexibility to craft radically new combat doctrine based on new facts in WWII in Cryptonomicon, absolutely one of my favorite books).

As for Pearl Harbor, I am reminded of a quote that was attributed to Frank Borman (at least in the From the Earth to the Moon documentary) when he was testifying about the Apollo 1 fire.  He called it "a failure of imagination" -- no one was even thinking about danger on the ground, all the focus was on space.  At the end of the day, the ultimate answer for Pearl Harbor's negligence in readiness was a failure of imagination.   They may have had war games and studies discussing Pearl Harbor attacks, and they may have addressed the possibility intellectually, but no one in command really believed that a couple of hundred aircraft would suddenly appear over peacetime Honolulu dropping bombs and torpedoes.

Selection Bias

I thought it was kind of interesting that upon reading this McKinsey & Co study (currently the top one in the list) on education, Kevin Drum and a number of other left 'o center blogs pulled out this one chart to highlight.  It shows starting teacher pay  (i.e. out of college) as a percent of the economy's average)

Blog_mckinsey_teacher_starting_pay

The author's of the study argue that the countries higher on this list also have better student results.  Now, I will confess that this is a pretty interesting finding in the study -- that starting teacher pay is more important than teacher pay in later years, because the key is to attract talented people right out of college away from other professions.  Interesting. 

But here is the quite fascinating selection bias by the lefty blogs:  I have read the whole report, and this is absolutely the only chart in the whole study that in any way, shape, or form might be interpreted as a call for higher government education spending.  Even more interesting is what these bloggers left out.  This is the other half of the starting teacher pay analysis Drum et. al. chose note to include, and makes clear that even this chart is not a call for more total spending:

South Korea and Singapore employ fewer teachers than other systems; in effect, this ensures that they can spend more money on each teacher at an equivalent funding level.  Both countries recognize that while class size has relatively little impact on the quality of student outcomes (see above), teacher quality does.  South Korea's student-to-teacher ration is 30:1, compared to an OECD average of 17.1, enabling it in effect to double teacher salaries while maintaining the same overall funding level as other OECD countries....

Singapore has pursued a similar strategy but has also front-loaded compensation.  THis combination allows it to spend less on primary education than almost any other OECD and yet still be able to attract strong candidates into the teaching profession.  In addition, because Singapore and South Korea need fewer teachers,  they are also in a position to be more selective about who becomes a teacher.  This, in turn, increases the status of teaching, making the profession even more attractive.

Whoops!  Don't want our friends at the NEA to see that!  Most of the study turns on McKinsey's finding that teacher quality drives student results, way ahead of any other factor, from class size to socioeconomic background:

Teacherquality

Well, now the NEA might be getting really nervous.  Something like this might cause parents to do something rash, like demand that low-performing teachers get fired.  Gasp.

Anyway, to get back to the cherry-picking and selection bias issue, the study is pretty clear that it thinks that "more spending" is a failed strategy for improving public education
Education1

If school choice is off the table, then I would be very supportive of a program to increase starting teacher pay, funded by larger class sizes and substantial reductions in useless administrators and assistant principals.  Anyway, it is kind of an interesting study, though you may find the pdf file format really irritating to try to read.  Lots of funny formatting.
