Elon Musk explains Tesla’s pure vision approach to Autopilot and Full Self-Driving
A recent set of updates from Elon Musk has revealed that Tesla is looking to eventually update its Autopilot and Full Self-Driving suite to a camera-based system. This means that in the future, Tesla’s all-electric vehicles would be navigating themselves and performing driver-assist functions without the use of components such as radar.
Musk’s update came as a response to a post from Tesla owner and FSD Beta user @WholeMarsBlog, who shared a clip of his Model 3 navigating away from a parking lot to its destination without input from its driver. In his response, Musk noted that FSD Beta V9.0, which has been highly-anticipated by the EV community, is almost ready.
Almost ready with FSD Beta V9.0. Step change improvement is massive, especially for weird corner cases & bad weather. Pure vision, no radar.

Elaborating further, Musk explained that the V9.0 update should improve the FSD Beta’s performance in corner cases and bad weather, which remain challenging to the advanced driver-assist system today. But this was not all, as Musk noted that the update would be “pure vision, no radar.” When prodded further, the Tesla CEO admitted that Tesla eventually plans to get rid of radar altogether in its future vehicles.
Unsurprisingly, Musk’s statements about Tesla’s impending removal of radar attracted its own fair share of critics, many of whom argued that a pure vision approach is a step backward. This is especially notable as Tesla is already using fewer sensors for its driver-assist systems compared to competitors like Cruise and Waymo, both of whom rely on lidar and high-definition maps to navigate.
Musk responded to these concerns, highlighting that ultimately, vision has the potential to be far superior to radar.
Sensors are a bitstream and cameras have several orders of magnitude more bits/sec than radar (or lidar).
Radar must meaningfully increase signal/noise of bitstream to be worth complexity of integrating it.
As vision processing gets better, it just leaves radar far behind.

“When radar and vision disagree, which one do you believe? Vision has much more precision, so better to double down on vision than do sensor fusion. Sensors are a bitstream and cameras have several orders of magnitude more bits/sec than radar (or lidar). Radar must meaningfully increase signal/noise of bitstream to be worth complexity of integrating it. As vision processing gets better, it just leaves radar far behind,” Musk explained.
Tesla’s approach to full self-driving is partly based on the notion that humans do 100% of their driving through vision alone, without any radar or lidar use. This was highlighted by Tesla executives since Autonomy Day back in 2019, when the company unveiled its custom FSD computer. As for concerns about whether cameras could provide the same level of safety as radar in detecting what is happening several cars ahead, Musk noted that there’s a high probability that vision could perform just as well.
These things are best thought of as probabilities. There are 5 forward-facing cameras. It is highly likely that at least one of them will see multiple cars ahead.

“These things are best thought of as probabilities. There are 5 forward-facing cameras. It is highly likely that at least one of them will see multiple cars ahead,” Musk said.
Tesla is not the only company in the market that is looking into a vision-only approach. Last year, Intel Corp released a video of an autonomous car from MobilEye that was navigating around Jerusalem for about 20 minutes. Unlike other self-driving vehicles, MobilEye’s car was only equipped with a suite of cameras and nothing else. The brief video was impressive, showing the MobilEye autonomous car going through four-way intersections with no traffic lights, as well as inner-city lanes that required the vehicle to avoid pedestrians.

Tesla exec: Preparations underway but no firm timeline yet for FSD rollout in China
The information was related by Tesla China Vice President Grace Tao in a comment to local media.
Tesla has not set a specific launch date for Full Self-Driving in China, despite the company’s ongoing preparations for a local FSD rollout.
The information was related by Tesla China Vice President Grace Tao in a comment to local media.
Tesla China prepares FSD infrastructure
Speaking in a recent media interview, the executive confirmed that Tesla has established a local training center in China to support the full adaptation of FSD to domestic driving conditions, as noted in a report from Sina News. However, she also noted that the company does not have a specific date when FSD will officially roll out in China.
“We have set up a local training center in China specifically to handle this adaptation,” Tao said. “Once officially released, it will demonstrate a level of performance that is no less than, and may even surpass, that of local drivers.”
Tao also emphasized the rapid accumulation of data by Tesla’s FSD system, with the executive highlighting that Full Self-Driving has now accumulated more than 7.5 billion miles of real-world driving data worldwide.
Possible 2026 rollout
The Tesla executive’s comments come amidst Elon Musk’s previous comments suggesting that regulatory approval in China could arrive sometime this 2026. During Tesla’s annual shareholder meeting in November 2025, Musk clarified that FSD had only received “partial approval” in China, though full authorization could potentially arrive around February or March 2026.
Musk reiterated that timeline at the World Economic Forum in Davos, when he stated that FSD approval in China could come as early as February.
Tesla’s latest FSD software, version 14, is already being tested in more advanced deployments in the United States. The company has also started the rollout of its fully unsupervised Robotaxis in Austin, Texas, which no longer feature safety monitors.

Tesla Semi lines up for $165M in California incentives ahead of mass production
The update was initially reported by The Los Angeles Times.
Tesla is reportedly positioned to receive roughly $165 million in California clean-truck incentives for its Semi.
The update was initially reported by The Los Angeles Times.
As per the Times, the Tesla Semi’s funding will come from California’s Hybrid and Zero-Emission Truck and Bus Incentive Project (HVIP), which was designed to accelerate the adoption of cleaner medium- and heavy-duty vehicles. Since its launch in 2009, the HVIP has distributed more than $1.6 billion to support zero-emission trucks and buses across the state.
In recent funding rounds, nearly 1,000 HVIP vouchers were provisionally reserved for the Tesla Semi, giving Tesla a far larger share of available funding than any other automaker. An analysis by the Times found that even after revisions to public data, Tesla still accounts for about $165 million in incentives. The next-largest recipient, Canadian bus manufacturer New Flyer, received roughly $68 million.
This is quite unsurprising, however, considering that the Tesla Semi does not have a lot of competition in the zero-emissions trucking segment.
To qualify for HVIP funding, vehicles must be approved by the California Air Resources Board and listed in the program catalog, as noted in an electrive report. When the Tesla Semi voucher applications were submitted, public certification records only showed eligibility for the 2024 model year, with later model years not yet listed.
State officials have stated that certification details often involve confidential business information and that funding will only be paid once vehicles are fully approved and delivered. Still, the first-come, first-served nature of HVIP means large voucher reservations can effectively crowd out competing electric trucks. Incentive amounts for the Semi reportedly ranged from about $84,000 to as much as $351,000 per vehicle after data adjustments.
Unveiled in 2017, the Tesla Semi has seen limited deliveries so far, though CEO Elon Musk has recently reiterated that the Class 8 all-electric truck will enter mass production this year.

Tesla reveals major info about the Semi as it heads toward ‘mass production’
Some information, like trim levels and their specs were not revealed by Tesla, but now that the Semi is headed toward mass production this year, the company finally revealed those specifics.
Tesla has revealed some major information about the all-electric Semi as it heads toward “mass production,” according to CEO Elon Musk.
The Semi has been working toward a wider production phase after several years of development, pilot programs, and the construction of a dedicated production facility that is specifically catered to the manufacturing of the vehicle.
However, some information, like trim levels and their specs were not revealed by Tesla, but now that the Semi is headed toward mass production this year, the company finally revealed those specifics.
Tesla Semi undergoes major redesign as dedicated factory preps for deliveries
Tesla plans to build a Standard Range and Long Range Trim level of the Semi, and while the range is noted in the company’s newly-released spec list, there is no indication of what battery size will be equipped by them. However, there is a notable weight difference between the two of roughly 3,000 lbs, and the Long Range configuration has a lightning-fast peak charging speed of 1.2 MW.
This information is not available for the Standard Range quite yet.
The spec list is as follows:
- Standard Range:
- 325 miles of range (at 82,000 lbs gross combination weight
- Curb Weight: <20,000
- Energy Consumption: 1.7 kWh per mile
- Powertrain: 3 independent motors on rear axles
- Charging: Up to 60% of range in 30 minutes
- Charge Type: MCS 3.2
- Drive Power: Up to 800 kW
- ePTO (Electric Power Take Off): Up to 25 kW
- Long Range:
- Range: 500 miles (at 82,000 lbs gross combination weight)
- Curb Weight: 23,000 lbs
- Energy Consumption: 1.7 kWh per mile
- Powertrain: 3 independent motors on rear axles
- Charging: Up to 60% of range in 30 minutes
- Charge Type: MCS 3.2
- Peak charging speed: 1.2MW (1,200kW)
- Drive Power: Up to 800 kW
- ePTO (Electric Power Take Off): Up to 25 kW
It is important to keep in mind that the Semi is currently spec’d for local runs, and Tesla has not yet released or developed a sleeper cabin that would be more suitable for longer trips, cross-country hauls, and overnight travel.

Instead, the vehicle will be initially used for regional deliveries, as it has in the pilot programs for Pepsi Co. and Frito-Lay for the past several years.
It will enter mass production this year, Musk confirmed on X over the weekend.
Now that the company’s dedicated Semi production facility in Sparks, Nevada, is standing, the timeline seems much more realistic as the vehicle has had its mass manufacturing date adjusted on several occasions.
