US President Biden’s union-friendly $4,500 EV tax credit buff is facing a big challenge
The Biden administration’s proposed $4,500 EV tax credit buff for electric and electrified vehicles made in a union plant in the United States is meeting a big challenge. The union-friendly proposal is poised to undergo a review from the office of Elizabeth MacDonough, the Senate parliamentarian, who would then determine if the incentive qualifies under the US’ budget rules.
The $4,500 tax credit, which would be given to vehicles produced in the United States using union labor, stands to favor the Detroit Big Three heavily. Due to its overtly pro-union nature, the incentive has attracted a lot of criticism, particularly from automakers who are operating in the United States without union labor. These include Japanese carmakers Toyota and American EV maker Tesla.
Democratic Senator Joe Manchin, whose state of West Virginia hosts Toyota facilities, has expressed his disapproval of the proposed $4,500 tax credit addition for union-made EVs. In an interview with Automotive News last month, Manchin noted that the US government should not use tax dollars to pick winners and losers and that products made by companies should be able to speak for themselves.
“This is wrong. This can’t happen. It’s not who we are as a country. It’s not how we built this country, and the product should speak for itself. We shouldn’t use everyone’s tax dollars to pick winners and losers. If you’re a capitalist economy that we are in society, then you let the product speak for itself, and hopefully, we’ll get that, that’ll be corrected,” Manchin said.
If the Senate parliamentarian’s office concludes that the union-friendly $4,500 EV tax credit does not mesh with budget rules, Democrats may end up going back to the drawing board, or worse, remove the measure altogether, according to a Bloomberg report. Maryland Democratic Senator Ben Cardin, for his part, has noted that changes to the Biden administration’s proposed EV tax credit are already being discussed due to opposition from political figures such as Manchin.
“There have been some suggestions to alternatives by those that opposed it initially, and they are being looked at. It’s an evolving discussion,” Cardin said.
The Biden administration’s proposal would result in the current $7,500 EV tax credit being extended. An additional $500 would also be added to cars whose batteries were manufactured in the United States. These, together with a $4,500 additional credit if EVs were built in a union factory, could result in electric and electrified vehicle prices being lowered by as much as $12,500. Biden has also pushed for the buildout of an EV charging network across the United States.
Tesla CEO Elon Musk, however, noted during his interview at the Wall Street Journal’s CEO Council Summit that it would be better if the Biden administration’s proposals would not be passed. Musk even noted that he believes government support for the buildout of EV chargers is unnecessary.
“Unnecessary. I mean, do we need support for gas stations? So there’s no need for this support for a charging network. I’d delete it. I’m literally saying get rid of all subsidies. And also for oil and gas… Maybe (Tesla’s competitors) need it. I don’t know. But I think just generally, I’m in favor of deleting subsidies. When we started Tesla, there were no EV subsidies at all, and gasoline was super cheap. We did not anticipate any subsidies. That came later. The $7,500 tax credit came as a result not because of Tesla’s activity but because of General Motors’ lobbying. So I would just say delete them all,” Musk said.

Tesla FSD’s newest model is coming, and it sounds like ‘the last big piece of the puzzle’
“There’s a model that’s an order of magnitude larger that will be deployed in January or February 2026.”
Tesla Full Self-Driving’s newest model is coming very soon, and from what it sounds like, it could be “the last big piece of the puzzle,” as CEO Elon Musk said in late November.
During the xAI Hackathon on Tuesday, Musk was available for a Q&A session, where he revealed some details about Robotaxi and Tesla’s plans for removing Robotaxi Safety Monitors, and some information on a future FSD model.
While he said Full Self-Driving’s unsupervised capability is “pretty much solved,” and confirmed it will remove Safety Monitors in the next three weeks, questions about the company’s ability to give this FSD version to current owners came to mind.
Musk said a new FSD model is coming in about a month or two that will be an order-of-magnitude larger and will include more reasoning and reinforcement learning.
He said:
“There’s a model that’s an order of magnitude larger that will be deployed in January or February 2026. We’re gonna add a lot of reasoning and RL (reinforcement learning). To get to serious scale, Tesla will probably need to build a giant chip fab. To have a few hundred gigawatts of AI chips per year, I don’t see that capability coming online fast enough, so we will probably have to build a fab.”
NEWS: Elon Musk says FSD Unsupervised is “pretty much solved at this point” and that @Tesla will be launching Robotaxis with no safety monitors in about 3 weeks in Austin, Texas. He also teased a new FSD model is coming in about 1-2 months.

It rings back to late November when Musk said that v14.3 “is where the last big piece of the puzzle finally lands.”
With the advancements made through Full Self-Driving v14 and v14.2, there seems to be a greater confidence in solving self-driving completely. Musk has also personally said that driver monitoring has been more relaxed, and looking at your phone won’t prompt as many alerts in the latest v14.2.1.
This is another indication that Tesla is getting closer to allowing people to take their eyes off the road completely.
Along with the Robotaxi program’s success, there is evidence that Tesla could be close to solving FSD. However, it is not perfect. We’ve had our own complaints with FSD, and although we feel it is the best ADAS on the market, it is not, in its current form, able to perform everything needed on roads.
But it is close.
That’s why there is some legitimate belief that Tesla could be releasing a version capable of no supervision in the coming months.
All we can say is, we’ll see.

SpaceX IPO is coming, CEO Elon Musk confirms
However, it appears Musk is ready for SpaceX to go public, as Ars Technica Senior Space Editor Eric Berger wrote an op-ed that indicated he thought SpaceX would go public soon. Musk replied, basically confirming it.
Elon Musk confirmed through a post on X that a SpaceX initial public offering (IPO) is on the way after hinting at it several times earlier this year.
It also comes one day after Bloomberg reported that SpaceX was aiming for a valuation of $1.5 trillion, adding that it wanted to raise $30 billion.
Musk has been transparent for most of the year that he wanted to try to figure out a way to get Tesla shareholders to invest in SpaceX, giving them access to the stock.
He has also recognized the issues of having a public stock, like litigation exposure, quarterly reporting pressures, and other inconveniences.

As usual, Eric is accurate

Berger believes the IPO would help support the need for $30 billion or more in capital needed to fund AI integration projects, such as space-based data centers and lunar satellite factories. Musk confirmed recently that SpaceX “will be doing” data centers in orbit.
AI appears to be a “key part” of SpaceX getting to Musk, Berger also wrote. When writing about whether or not Optimus is a viable project and product for the company, he says that none of that matters. Musk thinks it is, and that’s all that matters.
It seems like Musk has certainly mulled something this big for a very long time, and the idea of taking SpaceX public is not just likely; it is necessary for the company to get to Mars.
The details of when SpaceX will finally hit that public status are not known. Many of the reports that came out over the past few days indicate it would happen in 2026, so sooner rather than later.
But there are a lot of things on Musk’s plate early next year, especially with Cybercab production, the potential launch of Unsupervised Full Self-Driving, and the Roadster unveiling, all planned for Q1.
Tesla has added the 15th automaker to the growing list of companies whose EVs can utilize the Supercharger Network this year, as BMW is the latest company to gain access to the largest charging infrastructure in the world.
BMW became the 15th company in 2025 to gain Tesla Supercharger access, after the company confirmed to its EV owners that they could use any of the more than 25,000 Supercharging stalls in North America.
Welcome @BMW owners.

Newer BMW all-electric cars, like the i4, i5, i7, and iX, are able to utilize Tesla’s V3 and V4 Superchargers. These are the exact model years, via the BMW Blog:
- i4: 2022-2026 model years
- i5: 2024-2025 model years
- 2026 i5 (eDrive40 and xDrive40) after software update in Spring 2026
- i7: 2023-2026 model years
- iX: 2022-2025 model years
- 2026 iX (all versions) after software update in Spring 2026
With the expansion of the companies that gained access in 2025 to the Tesla Supercharger Network, a vast majority of non-Tesla EVs are able to use the charging stalls to gain range in their cars.
So far in 2025, Tesla has enabled Supercharger access to:
- Audi
- BMW
- Genesis
- Honda
- Hyundai
- Jaguar Land Rover
- Kia
- Lucid
- Mercedes-Benz
- Nissan
- Polestar
- Subaru
- Toyota
- Volkswagen
- Volvo
Drivers with BMW EVs who wish to charge at Tesla Superchargers must use an NACS-to-CCS1 adapter. In Q2 2026, BMW plans to release its official adapter, but there are third-party options available in the meantime.
They will also have to use the Tesla App to enable Supercharging access to determine rates and availability. It is a relatively seamless process.
