Sorry if you misinterpreted my view. Having the Telsa OTA update function is a great benefit to the consumer just as it's
beneficial for other consumer products, e.g. PCs & cell phones. But just like with those products, there're limitations over
time (as systems evolve), e.g. a minimum required processor/memory, faster USB ports, 4G cellular radios, etc, that can't be OTAed. As an example,
my gen 1 Apple tablet no longer receives OTA updates. Again, the point is that the OTA function is limited, generally requiring
a dealer visit to re-flash (if possible) or a new ECU when the update is extensive or critical to vehicle safety.

Edit: Clarified time.

Restrictions? No there are not. Please site devices, examples, specifics. Other than slow downloads on weak cellular (moot) or when no wifi is available what EACTLY are you talking about? You have implied and stated this before yet Tesla can update any device and any level of firmware and would like to know of examples where the car needs to go to the dealer for this except in repair cases. What update failures please?

I still don't see how the introduction of the MCU2 shows that the OTA function is limited.


Nearly 17 years ago I worked on a carrier class PDSN/GGSN - the backend 'router' that gives cell phones internet access. We started out with a few separate boards in a massively parallel system that each had different firmware, FGPA, and microcode images, as well as an operating system image with user-space router that needed to boot on top of this. Most of those images were written to different flash parts accessible by different buses. Updating a board required a lot of technician time - and an early problem was finding boards with one or other image out-of-date. Another engineer and myself designed a scheme to encapsulate all the images into a single boot image, and worked on dynamic update logic to reflash appropriate parts of the system at runtime. Our approach enabled complete dynamic updates on the system, the logical equivalent of Tesla's OTA (there was no "over-the-air" in our system).

At the time we were told it our approach would never work for processor and support chip microcode... but we proved such naysayers wrong by building a working system. When we built the 2nd generation boards using Intel parts (the first generation used Broadcom MIPS-based SOCs), we had our single boot image support all the firmware, FPGA, and microcode images for both generations of board. Cisco still lists a "future-proof architecture" as one of its key selling points.

At least they did it in April instead of January. :lol:

Now that loaded Ss can be picked up for about the price of a new LEAF, buying one may seem attractive at first glance, but...

Sounds like this early S probably cost the first owner something approaching $1-per-mile in TCO.

To the second owner, good luck...

Why Wait For A Tesla Model 3 When You Can Have A Model S For $33k?

...This 2012 Model S, boasting 107,000 miles (172,200 km) on the clock, for example, cost him just $33,500.

Right off the bat, Hoover pretty much knew what to expect thanks to a previous Model S experience. With three out of the four retractable door handles already replaced, he says that one of them is still on track to fail – a $1,000 fix…

Another costly item that had also been replaced was the $4,000 touchscreen, which has been known to fail on early cars such as this 2012 one. Despite still operating on the old 3G network, the infotainment system works well, as do all the car’s electronics.

What about the battery?

The battery represents the main issue with old electric cars. However, even after 107,000 miles, this Tesla’s battery is still at 90% of its original capacity, which matches the expected rate of degradation in the Model S.

Finally, this car offers an extra peace of mind by having the extended warranty. Instead of the standard 4-year/50,000-mile bumper-to-bumper coverage, this 2012 Model S has an 8-year/unlimited mileage warranty, which means that even if something does go wrong with the battery or the drivetrain, Tesla should fix it for free within the next two years...

Not exactly a surprise that the S takes first place:

Tesla targeting First Responders?

Tue May 29, 2018 6:32 pm

http://abc7.com/autopilot-tesla-crashes ... c/3536419/

Two of the three Tesla autopilot collisions cited in this article are into first responder vehicles - 1 fire, 1 police. The other was a concrete wall. A conspiracy theorist could suggest Tesla is anti-government. :lol:

Could this be the real reason Musk wants to control what the media reports?

"Tesla has said that while its autopilot system is supposed to help detect nearby vehicles and avoid collisions, it shouldn't be used in areas with intersections, stop signs, red lights or suddenly changing traffic patterns." So this really is only for long rural highways... Somehow a lot of their customers aren't getting this memo.

Tesla goes up in flames in video captured by actor Mary McCormack

Actor says husband was flagged down by passersby who told him to get out

Actor Mary McCormack has shared video of her husband’s Tesla car catching fire while in traffic in California. Flames can be seen shooting out from underneath the vehicle as it sits on the side of the road.

McCormack said in an accompanying tweet it was not the result of an accident and that the incident came “out of the blue”...

Tesla called the incident “an extraordinarily unusual occurrence” and said it was investigating...

The TSLA stooge site insideevs can't quite bring itself to accurately report that among BEVs only TSLA uses highly flammable battery packs, and even manages to point out the upside of having your BEV burst into flames...

Tesla Model S Catches Fire While In Motion – Not Caused By Crash

...While driving down the road, this Model S became engulfed in flames. The driver was alerted by other motorists and pulled over to quickly exit the vehicle unharmed...

Historically, electric car fires are rare, though it does seem Teslas are more prone to this than other electric cars. Part of this may lie in the cell chemistry, which is considered more volatile than what most other automakers employ. The upside is that Tesla batteries are the most energy dense in the electric car segment...

2 federal agencies take closer look into Tesla fire

One federal safety agency has dispatched an investigator and another says it is gathering information on a Tesla battery fire in Southern California.

The National Transportation Safety Board said Monday it is sending a technical specialist to watch Tesla's examination of the Model S that caught fire Friday on a street in West Hollywood. The National Highway Traffic Safety Administration said in a statement that it "continues to collect information regarding this incident and will take appropriate action as warranted."...

The NTSB makes recommendations on transportation safety issues, while NHTSA has authority to seek regulations and recalls...
