How Tesla CEO Elon Musk is WRONG WRONG WRONG About How the Fremont Assembly Plant Has Been in Operation for “Over 60 Years”Wednesday, November 26th, 2014
Here’s the background:
Which you can swallow or not, but I have a beef with this part in particular:
“However, the 20 year mark is simply when the last of the incentives expires. The Gigafactory itself will continue contributing economically to Nevada for much longer. Our automotive plant in California has been in operation for over 60 years with no foreseeable end in sight.”
Well, first of all, there’s nothing to stop Tesla or its successor from threatening to move away unless it receives another massive subsidy from the people of Nevada, right? So that’s just wrong.
But, more importantly, what’s up with this “over 60 years” thing? Let’s take a look.
Fremont Assembly began operations in 1963, right? 2014 minus 1963 = 51 years, right? 51 years is less than “over 60 years,” right?
And that doesn’t mean that this place was “in operation,” all that time, right?
And actually, it didn’t make sense to have such a big old GM factory in the Bay Area so it shut down in 1982. Let’s get some more deets:
“Operated as GM plant from 1963 to 1982, then became the site of NUMMI, GM’s joint venture with Toyota and the only major auto assembly plant remaining in California. Closed April 1, 2010, partially reopening as the Tesla Factory, an automobile assembly plant for Tesla Motors”
So Fremont Assembly was massively downsized when Toyota was coerced into starting up NUMMI, which lasted just 16 years.
Then NUMMI got massively downsized and now what’s left has been a Tesla factory for a couple years.
Now you might think that that’s good or bad, but this record sure doesn’t match what Elon Musk has to say.

The Craziest Bicycle I’ve Ever Seen in San Francisco: The Fortune Hanebrink All-Terrain Bike – Ride It to the South PoleWednesday, July 2nd, 2014
This is one of them “ice bikes” from Fortune Hanebrink.
Use it to tow your sledge to the South Pole.
As seen a few years back in the Western Addition:

All the deets:
“Engineered and handcrafted 8000 ft above sea level in Big Bear Lake, California, HANEBRINK Electric All-Terrain vehicles are the confluence of ingenuity, ecology, and luxury. The capabilities of the HANEBRINK are as limitless as your own sense of adventure; as a commuter vehicle, it is smooth and dynamic.
Nearly 10 years ago, national champion cyclist, bicycle innovator, and NASA aerospace engineer, Dan Hanebrink was approached by an Arctic explorer looking for an alternative to skis that could take him and his equipment across the icy terrain of Antarctica. Hanebrink created a bicycle unlike anything ever built before. The original “Ice Bike” by HANEBRINK had no plastic parts and used superfat, low-pressure tires that devoured all surfaces in all conditions silently and effortlessly. Today, our drive to create innovative outdoor recreational vehicles continues and is reflected in our mission to satisfy and serve the adventurous worldwide.
The HANEBRINK Electric All-Terrain Vehicle is the evolution of the original, revolutionary HANEBRINK design, combining state-of-the art green technology with an on-demand hybrid electric system and the latest in bicycle technology. Crank the throttle and the 600 watt motor powers the HANEBRINK to speeds up to 20 mph. If you want to go faster, just start pedaling.
Three design features help the HANEBRINK achieve outstanding on and off-road performance.
• The widest tires in the industry. The 20 x 8 inch tires radically increase the surface area where rubber meets road for enhanced stability at all speeds, added traction on rough terrain, and unprecedented float on sand and snow.
• A mid-mounted, bracket supported motor optimizes the vehicle’s center of gravity beneath the rider and enables tight turns, rapid weight shifting, and provides more stability.
• 14 speed gearing tuned for a wide variety of surfaces, grades, and utility applications including a low range capable of carrying up to 300 pounds of bulky cargo up steep terrain or deep into inaccessible areas.
With a single Lithium ion battery (LiFePO4), the HANEBRINK has a one hour run time and three hour recharge. For longer excursions, the rear rack can be fitted with up to five lithium ion batteries, a run time of over 5 hours and more than 100 miles of riding. The wide rear rack is standard HANEBRINK equipment and can hold up to 100 pounds of cargo.
The HANEBRINK can truly go anywhere on the planet while maintaining minimal environmental impact and zero-carbon emissions. Where can you go with one?”

Say, is this ride going to attract a certain “type” of person? You bet, you’ll see.
And say, should the U.S. or CA government subsidize the sale of these cars? Absolutely not.
That is all.

Uh Oh, Is Elon Musk Going to be In Trouble with the SEC? Should He have Disclosed Fires Investigation News?Wednesday, November 20th, 2013
Hey, what do you call this – would you call it the start of a federal investigation of the recent Tesla Model S fires, or at least the ones that occurred in America?
Hey, when did certain people at Tesla learn about it?
Hey, when did certain people at Tesla disclose it?
Is this time gap relevant to the people at the Securities and Exchange Commission?
It would be interesting to hear from somebody from Tesla about all this, non?

ACTION / SUMMARY INFORMATION
Action: A Preliminary Evaluation (PE) has been opened
The Office of Defects Investigation (ODI) is aware of two incidents occurring on US public highways in which the
subject vehicles caught fire after an undercarriage strike with metallic roadway debris. The resulting impact damage
to the propulsion battery tray (baseplate) initiated thermal runaway. In each incident, the vehicle’s battery monitoring
system provided escalating visible and audible warnings, allowing the driver to execute a controlled stop and exit the
vehicle before the battery emitted smoke and fire.
Based on these incidents, NHTSA is opening this preliminary evaluation to examine the potential risks associated with
undercarriage strikes on model year 2013 Tesla Model S vehicles.

The Mission of Tesla
By Elon Musk, Chairman, Product Architect & CEO
Our goal when we created Tesla a decade ago was the same as it is today: to accelerate the advent of sustainable transport by bringing compelling mass market electric cars to market as soon as possible. If we could have done that with our first product, we would have, but that was simply impossible to achieve for a startup company that had never built a car and that had one technology iteration and no economies of scale. Our first product was going to be expensive no matter what it looked like, so we decided to build a sports car, as that seemed like it had the best chance of being competitive with its gasoline alternatives.
FAIR ENOUGH, ELON.
I suspected that this could be misinterpreted as Tesla believing that there was a shortage of sports cars for rich people, so I described the three step “master plan” for getting to compelling and affordable electric vehicles in my first blog piece about our company. This was unfortunately almost entirely ignored.
AW, POOR ELON! NOBODY PAID ATTENTION TO WHAT YOU SAID? ACTUALLY, YOUR MASTER PLAN IS TO HAVE GLORY FALL UPON … ONE ELON MUSK, RIGHT? YOU’VE CONSISTENTLY OVERPROMISED AND UNDERDELIVERED, RIGHT? YOU’VE RELIED UPON GOVERNMENT SUBSIDIES AND YOU’VE STILL FAILED AT YOUR PROMISES OF AFFORDABILITY.
In order to get to that end goal, big leaps in technology are required, which naturally invites a high level of scrutiny. That is fair, as new technology should be held to a higher standard than what has come before. However, there should also be some reasonable limit to how high such a standard should be, and we believe that this has been vastly exceeded in recent media coverage.
FIRST OF ALL, ELON, WHO IS “WE?” SECOND OF ALL, ARE YOU PROPOSING A CHANGE TO THE FIRST AMENDMENT? SEEMS THAT WAY.
How Does the Tesla Model S Fire Risk Compare to Gasoline Cars?
THIS IS THE WRONG QUESTION, ELON. THIS IS LIKE SAYING THAT THE BOEING 787 IS PERFECT BECAUSE ITS NEW-SCHOOL BATTERIES HAVEN’T KILLED ANYBODY YET. THIS IS LIKE BOEING ASKING, “HOW DOES THE BOEING 787 FIRE RISK COMPARE TO AIRCRAFT WITH OLD-SCHOOL BATTERIES,” RIGHT? WELL ACTUALLY, BY THIS STANDARD, THE 787 HAS A PERFECT SAFETY RECORD. YOU SEE WHAT I’M SAYING HERE, ELON?
Since the Model S went into production last year, there have been more than a quarter million gasoline car fires in the United States alone, resulting in over 400 deaths and approximately 1,200 serious injuries (extrapolating 2012 NFPA data). However, the three Model S fires, which only occurred after very high-speed collisions and caused no serious injuries or deaths, received more national headlines than all 250,000+ gasoline fires combined. The media coverage of Model S fires vs. gasoline car fires is disproportionate by several orders of magnitude, despite the latter actually being far more deadly.
ALL THESE FACTS ARE IN RESPONSE TO THE WRONG QUESTION. ALSO, WHY DON’T YOU COMPARE YOUR NEW MODEL S CARS TO NEW GASOLINE CARS OF SIMILAR TYPE? LIKE, HOW MANY BRAND-NEW PORSCHE PANAMERAS CATCH FIRE AFTER RUNNING OVER TRAILER HITCHES? THAT WOULD BE USEFUL INFO COMPARED TO ALL YOUR BLATHER.
Reading the headlines, it is therefore easy to assume that the Tesla Model S and perhaps electric cars in general have a greater propensity to catch fire than gasoline cars when nothing could be further from the truth.
IT’S TOO EARLY TO MAKE THIS CALL, ELON. AND DO YOU THINK YOUR CUSTOMERS ARE STUPID, YOU KNOW, TO BE SO EASILY MISLED?
Journalists with a deep knowledge of the car industry, such as the news editor of Automotive News, understand and attempt to rebut this notion, but they have been drowned out by an onslaught of popular and financial media seeking to make a sensation out of something that a simple Google search would reveal to be false. I would also like to express appreciation for the investigative journalists who took the time to research and write an accurate article.
SO, PEOPLE WHO AGREE WITH YOU ARE JOURNALISTS WITH DEEP KNOWLEDGE AND THOSE WHO DON’T ARE THE HATED “MEDIA,” REALLY? AND WHAT’S REVEALED TO BE FALSE? YOUR CARS CAUGHT ON FIRE, RIGHT? THE FEDS ARE LOOKING INTO THIS SITUATION, RIGHT?
The degree to which this is outrageous is described well in the above-mentioned Automotive News article. There are now substantially more than the 19,000 Model S vehicles on the road that were reported in our Q3 shareholder letter for an average of one fire per at least 6,333 cars, compared to the rate for gasoline vehicles of one fire per 1,350 cars. By this metric, you are more than four and a half times more likely to experience a fire in a gasoline car than a Model S! Considering the odds in the absolute, you are more likely to be struck by lightning in your lifetime than experience even a non-injurious fire in a Tesla.
WELL THIS IS YOUR LINE, ELON, BUT WE’RE GOING TO HAVE TO WAIT AND SEE HOW THINGS SHAKE OUT, RIGHT?
Those metrics tell only part of the story. The far more deadly nature of a gasoline car fire deserves to be re-emphasized. Since the Model S went into production mid last year, there have been over 400 deaths and 1,200 serious injuries in the United States alone due to gasoline car fires, compared to zero deaths and zero injuries due to Tesla fires anywhere in the world.
AND YET, YOUR MODEL S DESIGN HAS ISSUES, RIGHT? THERE’S STUFF YOU CAN DO TO MAKE THINGS BETTER, RIGHT?
There is a real, physical reason for this: a gasoline tank has 10 times more combustion energy than our battery pack. Moreover, the Model S battery pack also has internal firewalls between the 16 modules and a firewall between the battery pack and passenger compartment. This effectively limits the fire energy to a few percent that of a gasoline car and is the reason why Dr. Shibayama was able to retrieve his pens and papers from the glove compartment completely untouched after the recent fire (caused by a high speed impact with a tow hitch). It is also why arsonists tend to favor gasoline. Trying to set the side of a building on fire with a battery pack is far less effective.
IS THAT A BAD THING, ELON, THAT GASOLINE HAS SUCH A HIGH ENERGY DENSITY? AND HEY, ELON, IF YOU’RE SO CONCERNED ABOUT SAFETY, WHY NOT VOLUNTARILY LIMIT THE SPEED AND ACCELERATION OF THE MODEL S? HOW ABOUT 0-60 MPH IN 8 SECONDS AND A TOP SPEED OF 80 MPH? ‘CAUSE IT SEEMS LIKE YOUR PRODUCTS AND YOUR CUSTOMERS ARE A BAD MIX, RIGHT? DRIVING AROUND SO FAST AND ALL. WHY ARE THE AMERICAN TAXPAYERS SUBSIDIZING YOUR COMPANY – SO IT CAN BUILD FAST CARS? WHEN ARE YOU GOING TO BUILD REGULAR OLD “AFFORDABLE” SLOW CARS? NEVER?
What About Safety Overall?
Our primary concern is not for the safety of the vehicle, which can easily be replaced, but for the safety of our customers and the families they entrust to our cars. Based on the Model S track record so far, you have a zero percent chance of being hurt in an accident resulting in a battery fire, but what about other types of accidents? Despite multiple high-speed accidents, there have been no deaths or serious injuries in a Model S of any kind ever. Of course, at some point, the law of large numbers dictates that this, too, will change, but the record is long enough already for us to be extremely proud of this achievement. This is why the Model S achieved the lowest probability of injury of any car ever tested by the US government. The probability of injury is the most accurate statistical figure of merit, showing clearly that the Model S is safer in an accident than any other vehicle without exception. It is literally impossible for another car to have a better safety track record, as it would have to possess mystical powers of healing.
CALL US WHEN THE SHUTTLE LANDS, ELON. DOES THE NHSTA APPROVE OF THE WAY YOU CROW ABOUT MODEL S SAFETY? NO IT DOES NOT? WHY IS THAT, ELON?
While we believe the evidence is clear that there is no safer car on the road than the Model S, we are taking three specific actions.
WELL, THAT’S REFRESHING! AFTER ALL THIS JIBBER JABBER, YOU’RE GOING TO CHANGE COURSE? LET”S TAKE A LOOK!
First, we have rolled out an over-the-air update to the air suspension that will result in greater ground clearance at highway speeds. To be clear, this is about reducing the chances of underbody impact damage, not improving safety. The theoretical probability of a fire injury is already vanishingly small and the actual number to date is zero. Another software update expected in January will give the driver direct control of the air suspension ride height transitions.
BUT WON’T THIS MOVE, WHICH “THE MEDIA” HAS BEEN CALLING FOR FOR A WHILE NOW, IMPROVE SAFETY? I THINK IT MIGHT. ANYWAY, IT LOOKS LIKE YOUR ALUMINUM “ARMOR PLATING” SCHEME DIDN’T WORK OUT AT THE RIDE HEIGHT YOU ORIGINALLY DESIGNED FOR. THIS IS CALLED A MISTAKE ELON. YES ELON, SOMETIMES YOU, THE GREAT AND POWERFUL OZ, MAKE MISTAKES.
Second, we have requested that the National Highway Traffic Safety Administration conduct a full investigation as soon as possible into the fire incidents. While we think it is highly unlikely, if something is discovered that would result in a material improvement in occupant fire safety, we will immediately apply that change to new cars and offer it as a free retrofit to all existing cars. Given that the incidence of fires in the Model S is far lower than combustion cars and that there have been no resulting injuries, this did not at first seem like a good use of NHTSA’s time compared to the hundreds of gasoline fire deaths per year that warrant their attention. However, there is a larger issue at stake: if a false perception about the safety of electric cars is allowed to linger, it will delay the advent of sustainable transport and increase the risk of global climate change, with potentially disastrous consequences worldwide. That cannot be allowed to happen.
[UPDATE: WELL, IT TURNS OUT THAT THE NHSTA ALREADY DISPUTES WHAT YOU’RE SAYING, ELON.] DID OJ SIMPSON CALL FOR THE LAPD TO INVESTIGATE THE DEATH OF HIS EX-WIFE AND THAT WAITER GUY? MAYBE HE DID. TRUTH BE TOLD, THE NHTSA WAS GOING TO INVESTIGATE YOUR DESIGN ANYWHO. SO YOUR REQUEST IS WORTHLESS. YOU’RE NOW BATTING .500 ELON. AND IF THE MODEL S GETS RECALLED YOU WILL COMPLY AND NOT CHARGE YOUR CUSTOMERS ANY MONEY? WELL THAT’S WHAT A RECALL IS, RIGHT ELON?
Third, to reinforce how strongly we feel about the low risk of fire in our cars, we will be amending our warranty policy to cover damage due to a fire, even if due to driver error. Unless a Model S owner actively tries to destroy the car, they are covered. Our goal here is to eliminate any concern about the cost of such an event and ensure that over time the Model S has the lowest insurance cost of any car at our price point. Either our belief in the safety of our car is correct and this is a minor cost or we are wrong, in which case the right thing is for Tesla to bear the cost rather than the car buyer.
FAIR ENOUGH, ELON. HEY WHAT ABOUT CHANGING THE DESIGN OF YOUR ARMOR (HEH) PLATING? OH, THAT WOULD COST TOO MUCH AND BE TOO EMBARRASSING? WELL, WE’LL SEE HOW THINGS GO. CERTAINLY OFFERING A FIRE WARRANTY IS CHEAPER THAN A REDESIGN, THAT’S FOR SURE.
All of these actions are taken in order to make clear the confidence we have in our product and to eliminate any misperceptions regarding the integrity of our technology and the safety of our cars.
WELL, ELON, IF I WERE YOU, I’D LOOK INTO REDESIGNING THE THIN SHEET OF ALUMINUM YOU’VE GOT BETWIXT THE ROAD AND YOUR THERMAL RUNAWAY DEVICE. I, FOR ONE, DON’T BUY YOUR BS. WE’LL JUST HAVE TO WAIT AND SEE WHAT THE FEDS COME UP WITH.
BUT PARTIAL DENIAL IS BETTER THAN FULL DENIAL, SO YOU’RE MAKING PROGRESS, ELON.
BABY STEPS, ELON. BABY STEPS.
I think I saw an ad for these A2B bikes just today in the SF Weekly.
They were never very popular but I did my best to discourage purchases, to the dismay of the Ultra Motors people.
These days, Ultra Motors is gone but A2B bikes are making a comeback aided by more realistic pricing.
Thusly, as seen with a flat tire:

IMO, you’re better off with a regular bike, one with puncture resistant tires and theft-hardened parts.
But that’s just me.
