Almost five months after SpaceX began the process of filling and testing the first custom-built propellant storage system for Starship, the largest rocket ever built, the company has finally begun to fill the fuel half of the ‘tank farm’.

SpaceX began delivering truckloads of liquid nitrogen (LN2) to the LN2 and liquid oxygen (LOx) sections of the tank farm in mid-September 2021, well before the farm was anywhere close to completion. In about a month, SpaceX accepted ~60 LN2 deliveries – enough to partially fill one of the farm’s seven cryogenic tanks. Instead of some operational purpose, that LN2 was likely used to clean and partially proof the farm’s three LOx tanks. Just two weeks later, the orbital tank farm received its first LOx deliveries.

At the time, mere days after the basic structure of the main tank farm storage system was effectively completed, most figured that it would take SpaceX about as long to clean, proof, and begin filling the farm’s two liquid methane tanks. That would not be the case.

SpaceX installed the second of the farm’s two vertical SpaceX-built cryogenic liquid methane (LCH4) tanks in mid-October 2021. All seven cryogenic tanks had ‘sleeves’ – designed to be filled with foam insulation – installed by the end of the month, effectively completing the farm’s basic structure half a year after assembly began. However, around the same time, SpaceX also installed two horizontal tanks that were also identified as LCH4 storage – giving the overall tank farm far more fuel storage than its oxidizer (LOx) tanks could match. Starship’s Raptor engines burn about 3.55 kilograms of LOx for every 1 kilogram of LCH4.

As work on the vertical LCH4 tanks appeared to slow to a crawl, it took until December 2021 for SpaceX to begin cleaning and proofing the farm’s horizontal LCH4 tanks with liquid nitrogen. By that time, a rough unofficial narrative had been constructed to explain the lack of progress on the farm’s fuel half. Namely, in an excellent Twitter thread, CSI Starbase made a strong case that SpaceX appeared to have designed the first orbital-class Starship tank farm – a compact and pleasingly symmetric set of eight vertical storage tanks – without taking into consideration rudimentary Texas regulations for the storage of liquid natural gas and methane. By all appearances, that conclusion was correct, as the farm was visibly violating several rules – namely the requirements that all LCH4 storage be surrounded by six-foot-tall retaining walls and that all associated plumbing not be situated under power cabling.

As it exists, the LCH4 side of the vertical tank farm violates both of those rules and it’s not obvious that there is actually enough space between the two vertical methane tanks to build a retaining wall with two feet of horizontal clearance. It’s possible that the situation is more complex and that SpaceX intentionally broke those rules or was pursuing an exception to them but the end result was that those vertical LCH4 tanks have yet to be finished, let alone cleaned or proof tested. Instead, SpaceX appears to have fully refocused on horizontal tanks and most recently tore down a dirt berm beside them and began preparing foundations for at least two or three more.

Those horizontal tanks appear to store about 1000 cubic meters (~35,000 ft^3) of LCH4, while the vertical tanks would have stored about 1800 m^3. To fully replace them, SpaceX will need approximately four horizontal tanks – two more in addition to the two already installed. Thankfully, SpaceX has finally begun filling the already installed tanks while it works to expand the methane farm, beginning with three truckloads on the very first day – February 13th, 2022.

To fill the two existing tanks, which may store enough methane to fuel a stacked Starship and Super Heavy about 4/5ths of the way, SpaceX will need around 40-50 more tanker deliveries. Since last November, SpaceX has completed more than 320 liquid nitrogen and 200 liquid oxygen deliveries – equivalent to about 6700 tons (~14.8M lb) of LN2 and 4200 tons (~9.3M lb) of LOx. If SpaceX maintains that average and focuses entirely on LCH4, the two horizontal tanks could be filled to the brim before the end of February.

Having a substantial amount of LCH4 stored at the orbital tank farm will finally allow SpaceX to attempt the first major wet dress rehearsals (WDRs) and, more importantly, the first full static fires with flightworthy Super Heavy booster prototypes. Of course, a tank farm with full supplies of LOx, LCH4, LN2, and their gaseous equivalents is also a necessity for the first orbital Starship launch attempt, which has most recently slipped from a target of mid-2021 to no earlier than (NET) Q2 2022, pending regulatory approval.

Tesla launches ‘Mad Max’ Full Self-Driving Speed Profile, its fastest yet

Tesla launched its fastest Full Self-Driving Speed Profile with the v14.1.2 Software Update on Wednesday, as “Mad Max” mode has overtaken “Hurry” as the most spirited travel option on FSD.

On Wednesday evening, Tesla’s Head of AI, Ashok Elluswamy, teased that the v14.1.2 Software Update would be released to those drivers in the Early Access Program (EAP). He said it was a “much-awaited feature.”

Tesla just teased something crazy with the next Full Self-Driving update

Many people, myself included, believed it would be the introduction of “Banish,” which would be a perfect complement to the Actually Smart Summon (ASS) suite, as it would find a parking spot and park itself after dropping you off at the front door of your destination.

However, Elluswamy’s post on X finished with two emojis: one a race car, the other being smoke behind the car.

On Wednesday night, we received the v14.1.2 software update to the new Model Y, which revealed that “Mad Max” mode was the new addition:

The release notes state that:

“Introduced new speed profile MAD MAX, which comes with higher speeds and more frequent lane changes than Hurry.”
It is pretty interesting that Tesla would introduce yet another speed profile that is even faster and more aggressive than “Hurry.” Personally, I’ve found Hurry to be realistic in terms of other drivers and their aggressiveness, speed of travel, and overall lane change behavior, especially on interstates.

Mad Max mode will be an interesting adjustment.

Tesla CEO Elon Musk first talked about Mad Max mode back in 2018 in posts on X, first mentioning the feature with the Tesla Semi:

Musk then teased Mad Max mode in 2019 with an early Autopilot update, stating that it would be an ideal option for aggressive traffic seen in places like Los Angeles. There was formerly a mode of the same name back in the late 2010s:

Now that it’s here, we’ll be testing it very soon and giving you a good idea of what to expect when it releases to others in the coming weeks.

Update 9:56 p.m. ET: We got it…

Tesla launches ‘Mad Max’ Full Self-Driving Speed Profile, its fastest yet

Tesla just teased something crazy with the next Full Self-Driving update, which will be released to Early Access Program (EAP) members today.

Tesla just recently released the v14 Full Self-Driving update, and it followed up just a few days later with v14.1.1.

The subsequent release helped refine a handful of things, especially an issue with stuttering at intersections and overall indecisiveness, but it was more of a smoothing over of the initial v14.1 Full Self-Driving release.

However, on Wednesday evening, Tesla’s Head of AI, Ashok Elluswamy, said that the company would be releasing v14.1.2 to EAP members today, and that it would “debut a much-awaited feature.”

He followed that up with a racecar emoji and a smoke emoji, potentially hinting toward something speed-related. However, it could mean something totally different.

Some suggested it was potentially a new Speed Profile that could rank above the “Hurry” option, but that seems unnecessary. As far as other features that have been teased, one that definitely comes to mind is the “Banish” feature that was recently teased by CEO Elon Musk.

Banish is essentially the finishing touch to Tesla’s Actually Smart Summon (ASS), which launched earlier this year.

While ASS will bring your car to your location using the Tesla app on your phone, Banish does just the opposite by dropping you off at the door of your destination and finding a parking spot on its own.

Elon Musk teases ‘Banish’ feature to pair perfectly with Summon

This was recently teased by Musk yet again, as he said earlier this month that Full Self-Driving would be capable of it very soon.

Based on what we’ve seen out of v14.1 and v14.1.1, there is some potential that Banish could be released and could be the feature that Elluswamy is hinting toward, although there is no direct evidence of that.

Luckily, I was able to get into the EAP, so as the feature is released and the Release Notes are available, we’ll be able to report on exactly what feature is on the way.

Tesla benefits from an incentive program in Texas that has become active following the loss of the $7,500 EV tax credit, which was a significant advantage for EV drivers.

In Texas, the State Commission on Environmental Quality has a grant program for light-duty motor vehicles that are either purchased or leased by consumers.

Referred to as the Light-Duty Motor Vehicle Purchase or Lease Incentive Program (LDPLIP), the program opened on October 13 and provides grants for consumers who want to buy new energy vehicles.

Will Tesla thrive without the EV tax credit? Five reasons why they might

The program allows for grants of up to $2,500 for electric or hydrogen fuel cell vehicles.

These are the eligibility criteria:

  • Individuals or entities who purchase or lease an eligible vehicle on or after September 1, 2025, and who apply for or acquire title and registration of the vehicle in Texas
  • Applicants must have taken possession of the vehicle before applying
  • Applicants must commit to operating and registering the vehicle in Texas for at least one year

Additionally, the car must:

  • Be included on the TCEQ Eligible Vehicle List
  • Be new and must not have been the subject of any prior retail sale or lease
  • Have a gross vehicle weight rating of 10,000 pounds or less

They are awarded on a first-come, first-served basis.

The good news is that Tesla’s entire vehicle lineup, as of October 7, qualifies. Here is what the LDPLIP’s list of qualifying vehicles shows for Tesla:

  • Tesla Cybertruck AWD
  • Tesla Cybertruck Beast
  • Tesla Model S AWD
  • Tesla Model S Plaid
  • Tesla Model X AWD
  • Tesla Model X Plaid
  • Tesla Model Y Long Range RWD
  • Tesla Model Y Long Range AWD
  • Tesla Model Y Performance
  • Tesla Model 3 Long Range RWD
  • Tesla Model 3 Long Range AWD
  • Tesla Model 3 Performance

This list was published during the day of October 7, which is coincidentally the same day Tesla launched its Tesla Model 3 ‘Standard’ and Tesla Model Y ‘Standard.’

We reached out to the program to confirm that these vehicles qualify for that grant, and we will update when we hear back.

With the loss of the Federal EV Tax Credit, local programs are still available to help with the cost of an EV. Although electric cars are affordable, there are benefits to choosing one, especially as these grant programs continue to become available.

The full list of vehicles that qualify for the grant is available here.
