Tesla’s Full Self-Driving (FSD) beta version 12 has been a hot topic over the last several months, representing an important switch that’s expected to help unlock higher levels of autonomy. And while the highly anticipated FSD v12 hasn’t yet been deployed publicly, some think that it could go out to a wider audience by the end of this month.
Last month, Tesla began rolling out the FSD beta v12.1 to Wave1, a group made up of over 15,000 employee vehicles. CEO Elon Musk went on to say that Tesla is currently performing extra testing on v12 before the software sees a wider release to the public.
In a recent look at where the FSD beta v12 is at ahead of its release, Teslascope shared a detailed breakdown of events leading up to this point on X over the weekend, adding that they’re “hopeful” that the software will be released sometime in late January. In addition, the account says that Tesla has begun internal tests of Actually Smart Summon (ASS), which has a “very likely chance” of going out later on in the first quarter.
Teslascope also points to recent feedback on the FSD beta v12 received from employees in the Wave1 group, with most answering that the software did indeed include some substantial improvements. These are summarized below, based on at least a dozen reviews shared with Teslascope from employees in California:
Tesla FSD beta v12.1: improvements to “human-like behavior” and general stability
- 72 percent said FSD beta v12.1 includes improvements in “human-like behavior” and general stability.
- 20 percent said there was no change to “human-like behavior” and general stability.
- 8 percent said these factors had worsened.
Tesla FSD beta v12.1: improvements to roundabout encounters
- ~40 percent said FSD beta v12.1 improved roundabout encounters had improved.
- ~50 percent said there was no change to roundabout encounters.
- ~10 percent said these factors had worsened.
Tesla FSD beta v12.1: improvements to lane-keeping
- 37 percent said FSD beta v12.1 offered improvements to lane-keeping.
- 60 percent said there was no change to lane-keeping.
- 3 percent said these factors had worsened.
Despite the hopefulness, the account also notes that the Cybertruck release has caused Tesla to put some extra energy into creating a stable FSD beta build for the vehicle, though Musk recently noted that the electric pickup would be the lowest priority for the FSD beta. Because of the extra effort put into this, the account says that delays could be possible and that they’re continuing to monitor the ongoing deployment of the version to those within the Wave1 group.
Tesla unveiled plans for the FSD beta v12 last year, featuring the elimination of over 300,000 lines of human-written code that previously controlled functions such as steering, acceleration and braking. Instead, v12 is expected to rely much more heavily on its neural network, training its artificial intelligence (AI) through massive amounts of real-time driving footage, and using the neural network to actually control the vehicle, rather than just detecting objects.
Musk also debuted the FSD beta v12 in a live stream in August, and he has also said that the version would lose its “beta” designation. Tesla began rolling FSD v12 out to employees in November, and screenshots from the Wave1 group appeared to show that the version will still use the beta moniker.

GM CEO Mary Barra says she told Biden to give Tesla and Musk EV credit
“He was crediting me, and I said, ‘Actually, I think a lot of that credit goes to Elon and Tesla…You know me, Andrew. I don’t want to take credit for things.”
General Motors CEO Mary Barra said in a new interview on Wednesday that she told President Joe Biden to credit Tesla and its CEO, Elon Musk, for the widespread electric vehicle transition.
She said she told Biden this after the former President credited her and GM for leading EV efforts in the United States.
During an interview at the New York Times Dealbook Summit with Andrew Ross Sorkin, Barra said she told Biden that crediting her was essentially a mistake, and that Musk and Tesla should have been explicitly mentioned (via Business Insider):
“He was crediting me, and I said, ‘Actually, I think a lot of that credit goes to Elon and Tesla…You know me, Andrew. I don’t want to take credit for things.”
GM CEO Mary Barra said to Andrew Sorkin at the New York Times Dealbook Summit that she pulled President Biden aside and said Tesla CEO @elonmusk deserved the credit for EVs:

Back in 2021, President Biden visited GM’s “Factory Zero” plant in Detroit, which was the centerpiece of the company’s massive transition to EVs. The former President went on to discuss the EV industry, and claimed that GM and Barra were the true leaders who caused the change:
“In the auto industry, Detroit is leading the world in electric vehicles. You know how critical it is? Mary, I remember talking to you way back in January about the need for America to lead in electric vehicles. I can remember your dramatic announcement that by 2035, GM would be 100% electric. You changed the whole story, Mary. You did, Mary. You electrified the entire automotive industry. I’m serious. You led, and it matters.”
People were baffled by the President’s decision to highlight GM and Barra, and not Tesla and Musk, who truly started the transition to EVs. GM, Ford, and many other companies only followed in the footsteps of Tesla after it started to take market share from them.

Musk would eventually go on to talk about Biden’s words later on:
“They have so much power over the White House that they can exclude Tesla from an EV Summit. And, in case the first thing, in case that wasn’t enough, then you have President Biden with Mary Barra at a subsequent event, congratulating Mary for having led the EV revolution.”
In Q4 2021, which was shortly after Biden’s comments, Tesla delivered 300,000 EVs. GM delivered just 26.

Tesla Full Self-Driving shows confident navigation in heavy snow
So far, from what we’ve seen, snow has not been a huge issue for the most recent Full Self-Driving release. It seems to be acting confidently and handling even snow-covered roads with relative ease.
Tesla Full Self-Driving is getting its first taste of Winter weather for late 2025, as snow is starting to fall all across the United States.
The suite has been vastly improved after Tesla released v14 to many owners with capable hardware, and driving performance, along with overall behavior, has really been something to admire. This is by far the best version of FSD Tesla has ever released, and although there are a handful of regressions with each subsequent release, they are usually cleared up within a week or two.
Tesla is releasing a modified version of FSD v14 for Hardware 3 owners: here’s when
However, adverse weather conditions are something that Tesla will have to confront, as heavy rain, snow, and other interesting situations are bound to occur. In order for the vehicles to be fully autonomous, they will have to go through these scenarios safely and accurately.
One big issue I’ve had, especially in heavy rain, is that the camera vision might be obstructed, which will display messages that certain features’ performance might be degraded.

I found the steepest, unplowed hill in my area and tested the following:
• FSD 14.2.1 on summer tires
• FSD 14.2.1 on winter tires
• Manual drivingBut I think the most impressive part was how FSD went DOWN the hill. FSD in the snow is sublime $TSLA pic.twitter.com/YMcN7Br3PU

Well.. I couldn’t let the boys have all the fun!
Threw the GoPro up and decided to FSD v14.2.1 in the snow. Roads were not compacted like the other day, a little slippery, but overall doable at lower speeds. Enjoy the video and holiday music 🎶

Moving into the winter months, it will be very interesting to see how FSD handles even more concerning conditions, especially with black ice, freezing rain and snow mix, and other things that happen during colder conditions.
We are excited to test it ourselves, but I am waiting for heavy snowfall to make it to Pennsylvania so I can truly push it to the limit.

Tesla hosts Rome Mayor for first Italian FSD Supervised road demo
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets.
Tesla definitely seems to be actively engaging European officials on FSD’s capabilities, with the company hosting Rome Mayor Roberto Gualtieri and Mobility Assessor Eugenio Patanè for a hands-on road demonstration.
The event marked the first time an Italian mayor tested the advanced driver-assistance system in person in Rome’s urban streets. This comes amid Tesla’s push for FSD’s EU regulatory approvals in the coming year.
Rome officials experience FSD Supervised
Tesla conducted the demo using a Model 3 equipped with Full Self-Driving (Supervised), tackling typical Roman traffic including complex intersections, roundabouts, pedestrian crossings and mixed users like cars, bikes and scooters.
The system showcased AI-based assisted driving, prioritizing safety while maintaining flow. FSD also handled overtakes and lane decisions, though with constant driver supervision.
Investor Andrea Stroppa detailed the event on X, noting the system’s potential to reduce severe collision risks by up to seven times compared to traditional driving, based on Tesla’s data from billions of global fleet miles. The session highlighted FSD’s role as an assistance tool in its Supervised form, not a replacement, with the driver fully responsible at all times.
Path to European rollout
Tesla has logged over 1 million kilometers of testing across 17 European countries, including Italy, to refine FSD for local conditions. The fact that Rome officials personally tested FSD Supervised bodes well for the program’s approval, as it suggests that key individuals are closely watching Tesla’s efforts and innovations.
Assessor Patanè also highlighted the administration’s interest in technologies that boost road safety and urban travel quality, viewing them as aids for both private and public transport while respecting rules.
Replies on X urged involving Italy’s Transport Ministry to speed approvals, with one user noting, “Great idea to involve the mayor! It would be necessary to involve components of the Ministry of Transport and the government as soon as possible: it’s they who can accelerate the approval of FSD in Italy.”
