"Fatal accident

The first known fatal accident involving a Model S occurred when the autopilot was active in Williston, Florida on 7 May 2016. In June 2016, the U.S. National Highway Traffic Safety Administration (NHTSA) opened a formal investigation into the accident working with the Florida Highway Patrol. According to the NHTSA, preliminary reports indicate the crash occurred when the tractor-trailer made a left turn in front of the Tesla at an intersection on a non-controlled access highway, and the car failed to apply the brakes.[166][167][168] The NHTSA's preliminary evaluation was opened to examine the design and performance of any automated driving systems in use at the time of the crash, which involves a population of an estimated 25,000 Model S cars.[169]

According to Tesla, "neither autopilot nor the driver noticed the white side of the tractor-trailer against a brightly lit sky, so the brake was not applied." The car attempted to drive full speed under the trailer, "with the bottom of the trailer impacting the windshield of the Model S." Tesla also stated that this was Tesla's first known autopilot-related death in over 130 million miles (208 million km) driven by its customers while Autopilot was activated. According to Tesla there is a fatality every 94 million miles (150 million km) among all type of vehicles in the U.S.[166][167][170] In January 2017, the NTSB report concluded Tesla was not at fault since the driver in the crash had seven seconds to see the truck and take action; the investigation revealed that the Tesla car crash rate dropped by 40 percent after autopilot was installed.[171][172]"

"Home charging

Tesla recommends that the primary method of charging be overnight charging at home, "just like your mobile phone". Tesla Model S vehicles come with the Mobile Connector, which allows charging at up to 40 amps and includes adapters for connecting to a variety of eletricity sources.[205] In North America, adapters for 120-volt NEMA 5-15 and 240-volt NEMA 14-50 outlets, as well as an adapter for SAE J1772 charging stations, are included.[205] In Europe, adapters for CEE red 3P+N+E, CEE blue 2P+E, CEE 7, and BS 1363 are available (inclusion varies by country), and an adapter cable for connecting to chargers with a Type 2 connector is also included.[206][207]

The Tesla Wall Connectors is available for installation at a home or business, and it allows charging at up to 19.2 kW in North America and 22 kW in Europe (although charging the vehicle at 11.5 kW requires the High Amerage Charger option on the vehicle).[205][206]"

"North America

The standard North American onboard charger accepts single phase 120 or 240-volt sources at a rate of up to 10 kW. Included adapters allow the car to charge from a standard 120 volt outlet, a 240 volt NEMA 14-50 outlet, a 208 volt leg to leg of a 208Y/120V 3-phase configuration, a 277 volt leg to neutral of a 480Y/277V 3-phase configuration and SAE J1772 public chargers. An optional upgrade for a second 10 kW onboard charger supports a total of up to 20 kW charging from an 80 amp available Tesla Wall Connector.[4] The North American connector uses a proprietary Tesla design.

Charging times vary depending on the battery pack's state-of-charge, its overall capacity, the available voltage, and the available circuit breaker amperage. From a 120 volt/15 amp household outlet, the range increases by 3.75 miles (6 km) for every hour of charging. From a 10 kW, NEMA 14–50 240 V/50 A outlet (like those used by RVs or standard cooking ranges), the charge rate is 28.75 miles (46 km) per hour. Using Tesla's 20 kW, 240 V High Power Wall Connector increases the rate to 57 miles (92 km) per hour if the car is configured with dual chargers (20 kW).[152]"

-- Most of you who own homes won't do this since you already run at least two other 10KW loads if not more, a stove and hot water heater. Adding this, another full time all night 10KW load will be too much AND local grids will not support this additional stress.

-- You will need to spend at least 10 hours at home charging this battery to get anything close to 200+ miles of range without using heat or AC or lights in the car.

-- Apartment dwellers will not be able to charge the car at home ever.

-- You and your spouse can not charge both of your electric cars at once.


"Autopilot[edit]

Main article: Tesla Autopilot

See also: Autonomous car and Connected car

Beginning in September 2014, Model S vehicles come equipped with a camera (supplied by Mobileye) mounted at the top of the windshield, forward looking radar (supplied by Bosch)[158][159] in the lower grill, and ultrasonic acoustic location sensors in the front and rear bumpers that provide a 360-degree buffer zone around the car. This equipment allows Model S to detect road signs, lane markings, obstacles, and other vehicles. In addition to adaptive cruise control and lane departure warning, a "Tech Package", together known as Autopilot, option enables semi-autonomous drive and parking capabilities.[160][161][162] All Model S cars sold since October 2014 have the option to enable Autopilot, which allows limited hands-free driving. Autopilot-enabled cars receive software wirelessly, the same as other car software updates.

According to Elon Musk, the Model S was designed to be a computer on wheels: "We really designed the Model S to be a very sophisticated computer on wheels. Tesla is a software company as much as it is a hardware company. A huge part of what Tesla is, is a Silicon Valley software company. We view this the same as updating your phone or your laptop."[163] Full autonomy is "really a software limitation: The hardware exists to create full autonomy, so it's really about developing advanced, narrow AI for the car to operate on."[164][165]"

-- Compeletely useless. You need more visual acuity and information than a camera and bumper sensors.

-- This is delusion and explains why someone is killed already being reliant on this fraud.

-- This has become a new religion for many and you need to see how the naive and uninformed are stepping up to the plate to market this failure to others based on them knowing nothing about what they speak or what Tesla and Elon Musk really offer. Robot cars meets Disney On Ice.

https://www.cnet.com/ro....del-s-the-battery-pack/

"Tesla Model S battery pack : We estimate the battery pack at 7 feet long and 4 feet wide.

Tesla's first production car, the Roadster, had a boxy shaped battery pack designed to fit right behind the seats of a Lotus Elise, the chassis that Tesla uses for the Roadster. As the Model S was designed and will be built by Tesla, the company had a lot more leeway on how it formatted the battery.

Tesla decided to package it in the floor of the car, contributing to the vehicle's handling by keeping its center of gravity low. Tesla has not specified how much the Model S' battery pack weighs, but it looked bigger than that in the Roadster, which comes in at close to 1,000 pounds. To our quick eyeballing of the Model S battery pack size, we're guessing at 7 feet long, 4 feet wide, and 6 inches thick.

Similar to the Roadster, the Model S battery pack is filled with cylindrical lithium ion cells dubbed 18650s. Tesla does extensive testing of these cells at its headquarters, cycling them at different temperatures, trying different discharge rates, and even crushing them. The data Tesla collects gets used to refine the specifications sent to its suppliers, among them Panasonic and Samsung.

When the Model S goes into production in 2012, customers will be able to specify three different battery packs, 160, 230, and 300 mile range capability. The Model S will accelerate to 60 mph in 5.6 seconds, with a top, governed speed of 120 mph.

Tesla Chief Engineer Peter Rawlinson explained to us that the battery pack also serves to help the Model S' torsional rigidity and safety. Cross members keep it from flexing much, and he anticipates that the Model S will lead its segment in rigidity, contributing to the car's handling. The pack also serves as a brace, helping to limit cabin intrusion during a side impact."

-- Reliance on a battery pack of this aspect ratio is a bad idea overall. This is not to be a stressed member of the car and overall it is too thin to accept or be used to stiffen the car this way. Nor should it.

"Tesla initially reported the total output in the P85D as the arithmetic addition of the maximum power of the individual electric motors at 691 hp (515 kW) but later reported it as 463 hp (345 kW) because the two motors do not give their maximum power at the same time.[76] "

-- A major flaw in the AC motor drives and controllers. Lack of symmetry as I'd expect.

-- I don't want her you can have her, she's too fat for me. WOW ! 5,000 lbs...

-- This thing is as heavy or heavier then a 1970 Buick Electra 225 which was 4,600–5,000 lb (2,100–2,300 kg).

-- A 1991 Ford Taurus weighs 3276lbs.

"Tesla, the electric-automobile manufacturer led by famed CEO Elon Musk, has struggled mightily with safety over the past few years. California nonprofit Worksafe, a worker safety advocacy group, recently made headlines when it reported that the injury rate at Tesla's Fremont, California, plant was more than 30 percent higher than the industry average in 2014 and 2015."

-- Fame is not fact or function.

"The 2012 Tesla Model S Performance model has a three phase, four pole AC induction 416 hp (310 kW) and 443 ft·lb (600 N·m) rear-mounted electric motor with copper rotor.[66] The base model uses a 362 hp (270 kW) and 325 ft·lb (440 N·m) motor."

-- Why so much HP and not DC? Why run inverters and AC drive motor controllers? DC drives are much more efficient and lower cost overall.

-- Elon Musk also felt that PayPal was best to run Windows Software over their current Unix platforms. I'd say he is a fool to say so.

-- Proves him the bigger fool now, MS Windows.... right...

"In March 1999, Musk co-founded X.com, an online financial services and e-mail payment company, with US$10 million from the sale of Zip2.[43][50][52] One year later, the company merged with Confinity,[51][54] which had a money transfer service called PayPal. The merged company focused on the PayPal service and was renamed PayPal in 2001. PayPal's early growth was driven mainly by a viral marketing campaign where new customers were recruited when they received money through the service.[55] Musk was ousted in October 2000 from his role as CEO (although he remained on the board) due to disagreements with other company leadership, notably over his desire to move PayPal's Unix-based infrastructure to Microsoft Windows.[56]"

-- Any software person who designs real time, embedded, military, and highly reliable systems says Windows is never used. Home use maybe. But that is all.

-- Musk is wrong and this naivete of his tech offer proves that out. This is a fad and gimmick.

http://blog.caranddrive....ity-on-conference-call/

"A simple conversion using the EPA filing’s listed voltage of the battery pack, at 350 volts, and the energy capacity, at 230 ampere-hours, returns a capacity of 80.5 kWh. Although CEO Elon Musk had previously said that the capacity of the top Model 3 wouldn’t be beyond 75 kWh, it’s likely he was referring to usable capacity, which is often around 90 percent (or a bit more for Tesla, some sources say) of the battery pack’s stated capacity."

-- So for that you will run a 10KW charger for 8.5 hours at home to charge. And battery voltage is close to 400 Volts.

-- The numbers work out the same for the discourse I did last year for Chevy Volt being batteries are batteries and Musk just buys them from Panasonic or someone else and solders them together in packs.

-- Big deal.... same problems exist and won't be solved any time soon.

-- Elon Musk, is a con man, of the ilk of Bill Gates, Mark Zuckerberg, and Jeff Bezos.


-- At home from their chart, 28 miles of range in one hour of charge time. So that is based on 40 amps of line power. You won't just toddle off to Home Depot and get an outlet for that and wire it up. We had 100amp service in our home, some others have 150amp.

-- Most homes already have an electric stove and hot water heater each taking 4 legs of two phase service being 40 amps each. So say 4500 watts times two for stove and for water heater. Or about 10kw each.

-- Your Tesla will need to consume 40amps continous for ten (more like 20) hours in order to add 280 miles of range. Charge tapers off as they say in their graphic doubling to get from 80 to 100 percent since the battery and electronics heat up internally.

-- You will want to keep the battery in the sweet spot to minimize full up and down cycles to extend life.

-- So this will be 5,000 watts or 5 KiloWatts for ten hours. Costing you likely $5.00 to charge this amount assuming your battery is about dead. Otherwise it will take longer. Running the car always using the last drop of charge will be freaky and tense. Akin to always having your gas tank on Empty... All of that matters.

-- Overall since this is one of the highest and most used (now) loads in the home you will be about doubling the required current capacity for you and all other homes in the area that host such cars.

-- Not easy. What did I miss?

http://www.teslamotors.com/supercharger

-- Most places won't be able to host in the home the 40amp feed to the car.

-- So 30 amp feed gets you 20 miles of range in one hour of charge time....

-- Assuming battery again is flat since charge tapers off up top...

-- And when someone tampers with or otherwise ruins a power point at one of these places?

-- What are the currents and voltages there? Ouch... No thanks.

-- So you are in Buffalo NY and it is -15F and you are getting 12 inches per hour of lake effect snow.... wind is blowing at 40mph gusting to 70mph and snow is drifting in quickly...

-- So you sit there and run the heat in your car to get to the next place in line at the charger....

-- Go ahead..... explain that to me.

David Shepardson, Reuters Jan. 24, 2018, 1:42 AM

"WASHINGTON (Reuters) - The U.S. National Transportation Safety Board (NTSB) said on Tuesday it was sending two investigators to examine the crash of a Tesla vehicle apparently traveling in semi-autonomous mode and a fire truck in California."

Did not notice the fire truck. Does not sound like a valid set of algorithms to self drive your car.

Can't see fire trucks, can't see tractor trailers, in this case a brick wall with wheels in front of you, and can't see traffic control barriers. Ouch.

"Tesla seeks to master autonomous driving someday through “fleet learning,” an approach that includes wirelessly uploading vast amounts of images and sensor data from owners’ vehicles. A fatal Model X crash suggests using that data to log potential road hazards and train its vehicles to avoid them would be a better near-term goal."

This is even worse and is nothing less than delusional thinking. You can't rely on such approaches to drive cars.

https://www.nytimes.com....rash-investigation.html

"A Tesla Model S, with its self-driving mode enabled. In a statement, the National Highway Traffic Safety Administration said it had sent an investigative team to examine the vehicle and the crash site in Williston, Fla"

"Federal regulators, who are in the early stages of setting guidelines for autonomous vehicles, have opened a formal investigation into the incident, which occurred on May 7 (2016) in Williston, Fla.

In a statement, the National Highway Traffic Safety Administration said preliminary reports indicated that the crash occurred when a tractor-trailer made a left turn in front of the Tesla, and the car failed to apply the brakes."

I learned something new today and this is worse and not better.....

"Tesla seeks to master autonomous driving someday through “fleet learning,” an approach that includes wirelessly uploading vast amounts of images and sensor data from owners’ vehicles. A fatal Model X crash suggests using that data to log potential road hazards and train its vehicles to avoid them would be a better near-term goal."

This is a problem since it likely relies on one of two solutions using sampled data:

1) Neural networks that offer a fuzzy programming solution where arbitrary matrices form input and output layers with some number of hidden layers in between. With input layers wired to vehicle sensors, output layers tied to device and vehicle control inputs, and hidden layers to form the abstraction and weighting factors to tie the events together. Even if they relate or do not relate to each other.

2) Or that data is used to build decision trees and programming based on situational paradigms. Avoid traffic circle at Main and Cedar Streets. Which of course won't ever work.

Neither of those approaches will work.

Neural nets are known not to work for simple problems as in using them to train character recognizers in order to "teach" computers to read printed text in images. These solutions fail and are not "Intelligence".

The abstraction is often arbitrary, difficult for humans to program and know, and the relations involve proxies that make accounting and by that diagnosing and testing, impossible to see and/or perform.

Most of these people are not good at programming computers, designing them, designing control systems using them, designing the embedded and other hardware to host them, and they are not good at driving and really don't know much about cars or driving in bad weather. They do things and don't know why they do them, why they are taught to do one thing VS another, and overall this problem gets worse again not better. The proxies and notion of "organic learning" claim to solve this. They do NOT. This is snake oil.

Beyond that Musk is admitting they don't have a solution at this point. Their computer that is driving your car is akin to an infant with a hand gun sitting behind the wheel of your 800hp electric car. You have trouble now.

He admits they still need to teach it. Suicide via murder.

"Tesla seeks to master autonomous driving someday through “fleet learning,” an approach that includes wirelessly uploading vast amounts of images and sensor data from owners’ vehicles."

Your death is part of their learning curve. So is the invasion of your privacy.

Other solutions that use vision systems outside the car will have same privacy problems and Musk has proven that they are unable to do simple process control and real time systems with their offers to provide inverter systems that take over 7 complete cycles of an AC power line to begin offering power to the line.

For their 50Hz solution that means 140msec. Too slow. And computing this waveform is trivial, take one sample point in time, and then interpolate forever moving forward. A sine wave. Big deal....

Driving a car is far more challenging and needs many many sets of inputs and outputs, the car has to compute control outputs many times a second, using far more difficult and time consuming programs, and it needs to sample chaotic and random and mostly not correlated, not periodic and regular (as electric power AC waveforms are), sensor inputs.

Musk gets the trivial cases wrong.

And now proves he is still hoping to make his cars "learn". Won't work.

Overhead vision systems outside the car will invade privacy, have huge loads and computing burdens placed on systems you already know as being useless. Being offers by Amazon, Google, Facebook, banking and credit who fail constantly in their ability (As does NSA) in their hope to host large numbers of computers and do work in parallel.

Such data needs to be culled in real time, all the time, and solutions need to be done with reliable and redundant pieces of hardware and the answers need to be made in fractions of a second.

When all that fails? Who do you blame?

So here is what I can think of so far based on my expertise in image processing, computer hardware and software design, embedded systems, real time systems, kernels, device drivers, sensors and automation, process control, data structure design, military and defense, high reliability systems, ruggedized systems, etc:

You are being misled on more than one front.

Statistics and logic are being offered to say:

1) This is better than having a human driver who makes errors at the wheel.

2) These numbers tell us that the car is safe since we have 1,000,000 (for instance) miles on X many cars.

3) Tesla auto pilot is better at driving than you are.

4) The combination of bad drivers and bad auto-pilot are better than just the human driver.

For point 4, those errors add.

These are all wrong overall. Human drivers largely act to preserve themselves and their investment in their cars and a want to avoid being arrested. Computers don't know how to know or do that.

This is akin to ABS systems where you tell drivers they can now rely on the car to help them be worse drivers and get away with it.

It offers a false sense of security and in order to respond to problems drivers need to be aware and in control all the time.

Part of me making decisions when driving a car even in good weather, requires ME to FEEL how the car is acting.

Soft tires, tricky road grades and crowns, slippery things on road, a wheel that is damaged or out of balance, a brake that is hung up, all matters and my fingers tell me this usually within a short period of time.

Computers won't.

Their numbers are specious and misleading, offering we have ALL THESE MILES ON THESE CARS! So what? You have billions more miles on the Ford Taurus in winter weather and not one of them has killed someone since it decided to drive itself.

Bad drivers will buy this bad car and then make bad decisions when their Tesla makes bad choices.

Simple really.

These people are full of crap.
