I mean sure. But my gas vehicle is purely recreational, it gets a few hundred miles a year at most. I really enjoy teaching myself car maintenance and repair with it. Being an 80s car, it’s super roomy in the engine area and easy to work on. No one is dying because I own and drive this car today. Someone might’ve died mining the lithium for my Tesla however. This is all to say that your comment is reductive.

If someone died mining our hypothetical battery, that is a choice they made (assuming that we all know working in mines is dangerous). OTOH we have little choice in breathing in smog... clean air is a communal resource we all have to share.

And the problem isn’t your gas vehicle that you rarely use, it’s the general concept of everyone from Volkswagen to our local auto sports enthusiasts thinking their smog doesn’t really matter that much.

For metric folks, this equates to nearly 600km. That's about as much as I want to drive in the space of a single day. Conceivably however, automated driving could mean doing longer distances. And at a cost much less than an airfare - just a lot more in time.

If you factor in 4-5 hours in overhead in order to take a flight, you can go a lot of places for a lot less and just slightly longer ride. I’m guessing 1/10 of the price for NY to Miami if you take 2-3 people

Gee, I hope they have some kind of system to track that. Maybe software even?

You jest, but years ago I worked for one of the largest auto parts places. You have no idea how many times you'd input year, make, model, and trim, just to be presented with multiple choice questions. Nobody knew how big their drums were, in inches, or the number of blades on their fan, the length of their belts, etc. Apparently a lot of mixing and matching happens. Some folks legitimately had to give us a prior year…

If you've ever been to a tesla service center, it's kind of interesting.

Cars glide in silently and when they sit there for a bit the words "Service Mode" come up in maybe 5" high letters on the dashboard.

There are lots of technicians on their computers. The car info comes up on the specific car and shows lots of history, where and when it was last serviced and so forth.

Each car seems to have it's own personal list of options and features, that shows up on the website when searching for cars, or when signing into you car portal.

folks have taken the time to document them:

https://github.com/timdorr/tesla-api

https://github.com/fredrikfjeld/tesla-options-decoder

I think all cars are like this, but telsa is less rigid / concerned about model years and just consults the database for the specific car's info at every step.

This is a nice upgrade for the Model S, however, I'm really curious what Tesla's design refresh roadmap looks like for their older models. The Model S has remained mostly the same since 2012, and while the design is pretty good, very few companies can get away without a major design refresh for 7+ years.

More than model S , model X badly needs a refresh. Thing started to look like a giant Prius.

revolutionizing the supply chain and auto industry

Walled garden revolution. Going to the breakers/wrecking yard for parts is akin to open source software. You are locking yourself into proprietary code, parts and pricing in this Tesla 'revolution'. A wing mirror costs $550 for example. Only authorized Tesla maintenance is permitted etc etc...

>A wing mirror costs $550 for example

I wish. I was quoted $1450 for a new wing mirror for my wife's X...

This sort of complexity is why I like pre smog era cars

In other words, let’s kill off people [0] from air pollution so car maintenance can be simpler. 0: http://www.prevenzione.ulss20.verona.it/docs/Sisp/Inquinamen...

I wonder how much of the additional complexity is actually necessary for lower emissions.

> Model S and Model X are now capable of achieving 200 kW on V3 Superchargers and 145 kW on V2 Superchargers. Together, these improvements enable our customers to recharge their miles 50% faster. What does that mean exactly? I'm sure there are sections of the charge curve where it is 50% faster, but you need to consider the entire charge curve to get a better sense of the improvement. The Tesla Model 3's charge times…

Interestingly, the charge rate across the entire curve sounds like an important metric but in practice it is nearly irrelevant.

If you drive an ICE car, you are used to filling your tank. Because once you've gone through the trouble of driving to a gas station and pulling out your credit card and unscrewing the cap, well you might as well top it off, right? Life is different with electric.

You might know, for example, that most Teslas operate day-to-day with their max battery charge limit set around 80% or below (it extends battery life). Charging at night is entirely effortless, so you put the charge into the battery that you'll need for the next day, or like me, you set it to give you 4x your daily commute and totally forget about it. Only before a particularly long road trip do you pop open the app and slide up the charge limit.

For Superchargers, the model is a bit different because this is charging that's happening on-demand while you wait in the car or are off getting a bite or whatever, during your trip. The best measure is to examine the portion of the curve that actual drivers spend actually charging their cars at an actual Supercharger. So here we have it;

"V3 Supercharging will ultimately cut the amount of time customers spend charging by an average of 50%, as modeled on our fleet data."

So this is truly an average of 50% faster, for actual Tesla drivers. ICE-age drivers who love to hate Tesla will insist you have to integrate the charge-rate curve, but as usual they will be entirely missing the point.

Tesla could spend an atrocious amount of time and money improving charging speed from 90 to 100%. That might be how you charge your phone, but it's actually not how Tesla drivers charge their cars (or how the onboard guidance computer will plan to charge your car when it sets the route for you), and would have almost zero benefit for the Fleet. Charging en-route is most efficiently done to boost the battery up to 70-80% and then you get going again.

Supercharger deployment, at least in the USA, is modeled such that there are almost no trips where you would benefit from, or need to, fully charge at a Supercharger, versus making two charging stops which would add up to less time charging, and driving out of your way to the charger, overall.

They also announced on Twitter: "As a thank you to our Tesla owners, all existing Model S and Model X owners who wish to purchase a new Model S or Model X Performance car will get the Ludicrous Mode upgrade, a $20,000 value, at no additional charge" https://twitter.com/Tesla/status/1120852649400623105

> Ludicrous Mode upgrade, a $20,000 value

I have a P85D. When Ludicrous Mode was announced, they offered it for $5000 as an upgrade.

I have no idea why it now supposedly costs $20,000.

That _IS_ my bad. I remembered the 5k rate, but for some reason I thought it was _per month_.

Duly corrected!

Alternative view: they’re desperate to get more high margin model S and X sales because owners are keeping their existing models too long.

Not surprised. They can't expect people to replace their car every two years as if it were an iPhone.

Time to introduce in-car purchases. Pay to overtake.
