The following is speculation based on the author’s experience, the known Model 3 feature set, and Tesla’s plans and recent statements.

Summary



The Model 3 reportedly contains Autopilot hardware dubbed “v2.5“

News outlets have yet to fully explore the meaning and purpose

Tesla isn’t providing a full explanation because they don’t want to tip their hand and they don’t need you to reserve a Model 3 — yet





Welcome to anti-sell and production-hell!



Screen-Shot-2017-08-15-at-9.26.37-AM.png


In a highly anticipated but somewhat awkward Model 3 delivery event, Elon Musk, ever the promoter, showed just one positive video of the car: the Model 3 being tested for side-impact where it effectively bounced off the testing device while one of the safest cars in the world, the Volvo S60, wrapped around it like a burrito.

Then he welcomed his fellow employees to production hell, showed a single slide that highlighted a handful of Model 3 specs, said nothing about the interior or any other features, and exited the stage faster than Jack Black hitting an empty mosh pit.

Don’t be fooled, this was the anti-sell.

Musk has been terrified of the Osborne effect since the original Model 3 unveiling, often publicly lamenting that people are mistaking the “3” for third generation and then taking that to mean it contains newer/better technology than S/X.

Note:  It actually does have newer/better/mind-blowing technology, but not in the way most people were thinking. The technology in question will be the subject of this post.

In fact, so pervasive is Tesla’s concern for the Osborne effect that they still anti-sell the Model 3 on it’s own webpage. Scroll half-way down and they’ll happily tell you all the ways the Model S is superior. Don’t reserve a Model 3; buy a Model S today!

Despite this concerted anti-sell and after only two 30 minute presentations and a handful of tweets, the Model 3 reservation count exceeds 455,000, more than the entire 2016 worldwide sales of the BMW 3 series.

Oops.

OK, great. So Tesla fooled 450,000 people into thinking they were buying tickets to a rock concert. They’re all just going to cancel anyway. What’s Model 3’s big secret?

Let’s walk through this mystery, step-by-step.

The Great Autopilot Head-Fake

Reports have said that the Model 3 has, what some are calling, Autopilot HW 2.5.

Here’s how Tesla responded to this report:

“The internal name HW 2.5 is an overstatement, and instead it should be called something more like HW 2.1. This hardware set has some added computing and wiring redundancy, which very slightly improves reliability, but it does not have an additional Pascal GPU.”

(The part in bold is key and will make sense by the end of this article.)

Still, HW 2.5 is being interpreted to mean that Tesla has already obsoleted the autopilot hardware found in the S and X and/or realized it’s not sufficient for full self-driving.

For example, the Verge wrote:



The updated onboard computer, dubbed “HW 2.5,” would seem to contradict the previous vow by Tesla CEO Elon Musk that all vehicles released since October 2016 would have the hardware necessary to achieve “full self-driving capabilities.

On Twitter, some of Tesla’s biggest fans have reached similar conclusions:

Screen-Shot-2017-08-15-at-9.27.37-AM.png
Are they right?  Did Tesla just declare AP hardware v2.0 incapable of full self-driving?

Well, as always, there’s another side to the story.  And — oh what a side it is.

First, let’s recall Tesla’s public plans.

Tesla’s Future Ride Sharing Network

In the second installment of his Master Plan, Musk outlined the future Tesla Ride Sharing Network as follows:

When true self-driving is approved by regulators, it will mean that you will be able to summon your Tesla from pretty much anywhere. Once it picks you up, you will be able to sleep, read or do anything else enroute to your destination.



You will also be able to add your car to the Tesla shared fleet just by tapping a button on the Tesla phone app and have it generate income for you while you’re at work or on vacation, significantly offsetting and at times potentially exceeding the monthly loan or lease cost.

Now let’s peel the layers of the HW 2.5 mystery.



There Can Be Only One

Screen-Shot-2017-08-15-at-9.28.39-AM.png


The Model 3, as it turns out, is Tesla’s Highlander.  

It’s the only car in Tesla’s current lineup capable of someday joining its ride sharing network. The S and X, despite appearing to share the same autopilot hardware, will not make it in current form, nor do they even make sense as robotaxis, given this imminent and cheaper alternative.

Aha! So everyone was right!

Let’s note the important distinction that everyone seems to be missing:  

Full self driving does not necessarily equate to ride sharing



Tesla is not saying that the S/X hardware can’t achieve full self-driving.  

And yet they’re not explaining the Model 3’s distinctive features because they’re already drowning in reservations and would rather you buy an S or an X.



But they left too many clues.

The Model 3 brings forward two very important innovations, one interior, one exterior. And, HW 2.5 is what’s needed to tie them together.

About That Model 3 Interior

The Model 3’s interior is certainly striking, if only for its minimalism. A quick comparison with two of its competitors.

From this, we can surmise that the Model 3 interior serves three purposes simultaneously.



It’s strikingly unique and unapologetically futuristic

It’s easier to manufacture (fewer parts)

It’s built for autonomous ride sharing



Yes, that last one. The Model 3 is built from the ground up to be the first candidate in Tesla’s future ride sharing network and the interior is the first piece of the puzzle.

The unique 15-inch screen is a hugely important feature.

Save for the window actuators (which are required) there are no other physical controls.

No radio.

No trunk latch.

No glove box handle.

No fiddly heating/air-conditioning vents.

Software Controls Go to the Next Level and Beyond

Who cares?  Tesla’s just cheap, right?

Not just cheap…  

Not having physical controls means everything in the Model 3 is software controlled. This means everything is configurable and remembered.  Everything. And more importantly, it’s remembered per person.

This also makes the main display the access point in order to do things like open the trunk or the glove box, or, in general, to operate anything.

Access to configurable touch screen controls can be either prevented or granted.

What are the first two concerns people mention when asked if they’d hypothetically share their car with others in a ride-sharing network?



 What if I leave something valuable in the car?

 What if someone pukes/destroys my interior?



As just illustrated, Tesla addressed the first issue through 100% software controls. Permissions for anything can be granted to the owner, but restricted from other parties.  



The glove box now acts as a safe that you don’t need to remember to lock.

The front and rear trunks are inaccessible without permission.  

Nothing proprietary or personal can be accessed from the main display



This has never been done before in the history of automotive.  And we’re only one third of the way through the mystery.

What about the second issue?

Monitoring the Interior

At CES 207 nVidia announced, among other things, AI Co-Pilot.  

They listed its features as facial recognition, head position and gaze tracking, natural language processing, voice speech capabilities, augmented lip reading, external environmental awareness.

nvidia_CES.jpg


As one would guess, it features a camera to keep an eye on the driver and interior cabin.  

The what?  What was that second one?

The interior cabin.  It monitors the interior cabin.

This would address the second piece of the ride-sharing interior puzzle: what if someone damages the interior?

And, in pouring over a video of the Model 3, someone noticed this.

Screen-Shot-2017-08-15-at-9.36.46-AM.png


An internal camera.

So, Tesla is not only using nVidia’s Drive PX2 board for autopilot, but they now appear to be using something very similar to its Co-Pilot technology to monitor the interior.

Let’s restate that for clarity — the Model 3 has a camera that can monitor the interior cabin in the event a third party damages something.

(Interior cameras will undoubtedly be standard in future robotaxi’s. And, yes, the car will likely not operate if the camera view is blocked. So keep your masking tape and magic markers at home.)

Also note that such a camera, not present on the S/X, would require computing power and new wiring to the Drive PX2/Co-Pilot board. Let’s recall Tesla’s statement to Electrek:

This hardware set has some added computing and wiring redundancy, which very slightly improves reliability, but it does not have an additional Pascal GPU.”

Are we getting it?  Tesla needed new hardware to address two of the biggest concerns in sharing one’s vehicle with a third party: restricting access to valuables and features, and monitoring the interior.  

But all of this still doesn’t work without one more innovation.

The Final Piece of the Ride-Sharing Puzzle

Screen-Shot-2017-08-15-at-9.38.28-AM.png
First we inserted keys.  

Then we inserted key fobs.

Now we have wireless key fobs that we keep in our pockets and can start the car with the push of a button.

Yet, none of these interactions are sufficient for a future ride sharing environment.  

You can’t lend your key fob to everyone who would ride in your car.  But, that’s OK.  It’s about to become obsolete.

The Backup Entry Option

As Model 3 videos began to surface it was quickly discovered that Tesla is replacing the key fob with an NFC key card. Entry via key card involves swiping it against the B-pillar, and then placing it in the cup holder.

tesla-model-3-keycard-packet-cupholder.jpg
While interesting, and simultaneously futuristic and (seemingly) a step backward, this is a red herring.

The key card is the secondary form of entry, and it’s purpose is to obsolete the key fob, not replace it. There’s something much more important in play.

The REAL Entry Option

Screen-Shot-2017-08-15-at-9.42.46-AM.png
The main form of entry to the Model 3 is actually your cell phone.

With the Tesla app and an Internet connection, one can press a button and lock/unlock the doors from anywhere in the world. Both the S and X also work this way.

Wait. What if you don’t have an Internet connection?  

And how is unlocking your phone, launching an app, waiting for it to load, and pressing a button possibly better than a key fob in your pocket??

Almost there.

Enter The Magic Protocol

As we know, everything’s better with Bluetooth. And so is ride-sharing.

Starting with the Model 3, Tesla’s mobile app will also run a persistent background service that uses Bluetooth LE to directly connect to the vehicle.

Bluetooth LE is an advertising/scanning-based approach that one can use to securely transmit encrypted public/private keys and data. It does not require explicit pairing like traditional Bluetooth.

In other words, with your phone in your pocket, the car will not only unlock as you approach but also know who you are and instantly configure itself with your preferences, privileges, and restrictions.

And that my friends is the final piece of the puzzle.



Tesla’s Entire Plan Revealed

Let’s recap.  Tesla needed new hardware to enable new features, not to change self-driving performance.

As such, Tesla is about to deliver, right under everyone’s noses:



Autopilot hardware it believes will be capable of full autonomy.

A 100% software-controlled vehicle that’s accessed identically by either its owner or a random person, and is fully customizable for each.

A camera to monitor the interior.

Vehicle entry with a mobile phone.



Autopilot hardware. A fully software controlled vehicle. An interior camera. Entry via a cell phone.

Autopilot hardware. A fully software controlled vehicle. An interior camera. Entry via a cell phone.

Are we getting it yet?

The Model 3’s design is NOT just to save money.

HW 2.5 isn’t about self-driving.

It’s about ride-sharing.

Screen-Shot-2017-08-15-at-9.43.37-AM.png


Conclusions

Despite misguided criticism, Tesla has not obsoleted Autopilot 2.0 hardware and this isn’t a “backup plan.” AP HW 2.5 is not about self-driving; it’s about ride-sharing. And Tesla doesn’t want to explain it — yet.

In short, with the Model 3, Tesla is delivering a mind-blowing electric vehicle that:





Incorporates everything Tesla believes is necessary for full autonomy

Incorporates everything needed to join its future ride sharing network

Will recognize you as you approach

Unlock your door and adjust your seat position

Restrict any parts of the car you’re not approved to access

Set the car to your temperature and aim the air vents where you prefer

Set all your radio presets

Queue your favorite streaming music or podcasts

(Someday) play your favorite movies and television shows



And, the “you” in question can be a complete stranger.

And all this happens instantly as you approach, without any manual interaction.

Expect more discussion on this from tech and auto industry reporters, and eventually the general public.

This is what Apple, GM, and others aspire to deliver three or more years from now.

Tesla isn’t going to explain it because, for now, they’d rather you buy an S or an X.

Despite keeping this secret they still have over 455,000 reservations. And counting.

The bottom line is that contrary to what Tesla says, the Model 3 is the most technologically advanced car that Tesla or anyone else has ever built.  

And it’s not even close.

Tesla is innovating at a rate unmatched in the auto industry. Not only are they planning years ahead but they’re also executing in a way that none of their peers can even conceive.

For contrast:

Mazda just announced a 20% improvement breakthrough in an ICE engine that it hopes to bring to market in 2019.  

Ford is adding 25HP to this year’s Mustang, and also adding a mute button, so the engine doesn’t annoy your neighbors.

These are ocean liners trying to catch a catamaran and they’re not even in the right body of water.

Is it any wonder Tesla accelerated their bond sale when it could have waited until 2018?

TMC Member Alketi is an electrical/software engineer with 25 years experience. He is also a Model 3 reservation holder.

Good supposition, and a real possibility. This doesn't mean that the S/X don't continue to be excellent and very attractive cars to be yearned after. I did find your right style a little 'harsh' -- for example quoting 'Tesla's biggest fans' with out some explicit sarcasm indication makes it hard to tell if you are spinning positive or negative on this story. EM knows that avoiding a dip in income during the critical early ramp of the 3 is important. Tesla is just trying to say that the S/X exist, and one can buy them immediately or custom order without great delay, but for most of us, the wait for our 3 is still long -- here in Canada our estimate is late 2018 :eek: unless we can some production in a window before the 200,000 rebate crossing :rolleyes:
 
The possibilities are inspirational! Besides the potential for "ride sharing" in the sense of a robo-taxi, this concept will allow a rapidly aging world population to remain increasingly mobile in a vehicle that will transport them safely to the most essential destinations - groceries, medical, visits to friends and family. In fact a family member or care giver could program a car to achieve these tasks from a distance for someone who is forgetful or can't adjust to new technology that is beyond their lifetime experience level. The future is at hand!

Although a smart phone will be the input for remote accessibility and the key card will be kept in a wallet or purse for backup entry, the smart phone is comparatively bulky and the key card could be inconvenient. I would like to see a "smart watch" with Bluetooth capability, worn on the wrist to gain entry with basic programmable functions and to set personal profiles. And that will happen too, sooner than later.
 
For me, ride sharing isn't about letting complete strangers pay me to use my car when I'm not using it. It's really unlikely I could ever get on board with that. No matter how polite most people are there are enough out there that are going to eat their lunch in your car, spill their coca cola, or scrape the door against something when entering/exiting the vehicle to EVER make it worth while FOR ME.

It doesn't matter if a camera caught what happened and they are liable or my insurance will pick it up. It's the irritation of dealing with the problem and the insult to my personal vehicle, which is an extension of me the way that a tailored suit is.

Where I see big value in this if I keep the car long term is that at some distant point in the future the car would be able to take under-age family members on errands that I don't have time to run. Or go pick up my take out food so that the car pulls up, alerts the establishment who puts my items in the frunk and then the car whisks it back to me.

That's the real value of this technology to me.

Hmm and at least you have the camera to catch "under aged family members" if they eat in, scratch your car etc. No I get it.
I would much rather deal with known family than strangers when things go sideways. Still not everyone can afford lease/loan payments and this would be a great option for someone of less means to own an awesome electric car.

With fully autonomous driving, what will all those "soccer Moms" do all day?

You can send your car out to run errands for you. Stop at the dry cleaners, do some banking, grab a pizza, pick up the bowling trophies, take kids to school, etc.

It can pick up your friends and relatives at the airport or Hyperloop platform.

Could change the way we live our lives.

If ride sharing works as Musk has contended, then a different way of thinking about the car is that once it has depreciated to whatever point you are comfortable, you can put it into service rather than selling it. IF these cars work as intended, then they should be able to go out and make $30-50 / day. You wouldn't want to put that kind of usage on your personal car, but it would be a terrific way of monetizing your car's end of life and recouping a goodly amount of what you put into it.

In effect, it puts a floor on the value of any used 2.5+ Tesla, since their value will not be based on what someone is willing to pay so much as the amount of revenue that they can produce in a given market.

The other thing to keep in mind is that Tesla is making the hardware investment now to make all of these cars capable of L5 autonomy in the future. This is a long term bet for them, but they will have very large market advantages entering the ride sharing market if 400-600k used Teslas can be put into use as autonomous taxis without any further capital cost.
 
Good blog, and overall agree with the conclusion. However, I disagree with the theory about using the internal camera as a security/audit device for ride sharing. For starters, it doesn't have full coverage of the interior.

If you have seen the NVIDIA Co-Pilot presentation, you can see NVIDIA's intended use is to assist the driver by checking the direction of the driver's gaze and their attentiveness, and for bringing things to their attention that they may not have noticed. (Sidenote: can't think of anything more annoying than being second-guessed as to whether or not I have noticed something on the road ahead. Bad enough when the missus does that). IMO Co-Pilot needs a HUD to be useful.

Using the principal of KISS, I would guess that Tesla put the camera is there to eliminate the need to hold the steering wheel to prove attentiveness for EAP, and to safely pass control back to the driver in FSD mode should when the need arises.

In the medium term, it could be used as a biometric device to ensure that the person who tries to drive the car is authorised to do so - either because they own the car, or because they are renting it through the Tesla Network. It could also ensure that the authorised driver is sitting in the driver's seat rather than their 12-year old daughter...

More effective than a password, but supremely annoying if it doesn't recognise you half-way through a drive because you just put your sunglasses on ;)

Agree voip-ninja, but think about it this way. People (entrepreneurs) can eventually buy Model 3s solely for ride-sharing. Ultimately, one of Tesla's automatic chargers can be set up and the whole thing will require very little interaction. Others can use the features just for friends/family.

Nice work on the article. Curious though if the S and X will get the ride-sharing-enabling upgrades soon. Why not?
Apparently S and X are getting the 2.5 HW, though it's not year clear if that includes the interior camera. What S/X don't have are 100% software controls. Can the frunk/trunk be prevented from opening? The glove-box? I'm not sure. The Model 3 makes more sense for future ride-sharing just based on it's price and design.

I agree that nVidia presented was a horrifyingly annoying implementation of Co-Pilot.

One thing I would caution is that while we know how nVidia used the camera, we don't know the field-of-view of Tesla's camera.

Tesla could easily increase the FOV and still observe the driver. If the entire car is built for ride-sharing, why would Tesla only focus the camera on the driver? Widen the FOV and also observe the interior. It's obvious. But, we'll see.

That "article" is on the same level as all the " 9/11 Bush did it "-tinfoil hat stories. Nothing but superlatives and fanservice in there, seriously....
All that`s missing is a picture of someone kneeling in front of a Musk-altar.....
At what point does the article stretch the truth to conspiracy levels? Yes, his writing is flowery and dramatic, but they are all valid assumptions based on facts. Please, provide details on what is unbelievable.

I don't believe in conspiracies nor would I characterize this as one. (I'm the author)

It's a rational choice for Tesla to not explain the full Model 3 use-model for two reasons:

1. They're drowning in reservations and would rather you buy an S/X today, rather than wait 18 months. That's rational, not conspiratorial.

2. They have a ton of work left to do on Autopilot and they still don't have any FSD features, so the Tesla Network is likely more than 2 years away.
 
I think the idea of it remembering your preferences is intriguing, but raises one interesting question: If you and another person who drives the car (such as spouse) approach, how does it know which one is the driver? I'm wondering if the USB ports for the phones can help in such cases. That is, plugging your phone into the driver's side charge port automatically syncs the system with that driver's preferences, and plugging the passenger's phone into the passenger USB automatically loads the passenger's side preferences.

Another good point. As a someone in UI what I would do would be to present two (or more) large buttons on the main display with the appropriate names. Driver presses his/her name and everything customizes.

Alternatively, they could base it off the phone dock, which would be more automatic, but I don't think you'd want to make that mandatory.
