Tesla CEO Elon Musk has frequently expressed his opinions on LiDAR in the past, but in recent days, the EV maker’s frontman has continued to discuss the weaknesses in the technology and why his company has relied on cameras.

He also mentioned the suite’s limits on Waymo’s capabilities.

Tesla completely abandoned using radar alongside its camera suite a few years ago, something it referred to as “Tesla Vision” at the time. For its vehicles, it has only used cameras since this transition, and Musk has never once shied away from this strategy.

Earlier this week, he discussed the reliance of LiDAR and radar by other companies:

“Lidar and radar reduce safety due to sensor contention. If lidars/radars disagree with cameras, which one wins?

This sensor ambiguity causes increased, not decreased, risk. That’s why Waymos can’t drive on highways.

We turned off radars in Teslas to increase safety. Cameras ftw.”

He continued with this narrative again and mentioned Waymo specifically on a second occasion.

Musk’s focus this time was on Waymo vehicles and their capabilities in adverse weather, specifically snow, rain, or even dust storms, and how LiDAR struggles to navigate in these conditions.

He said:

“LiDAR also does not work well in snow, rain or dust due to reflection scatter. That’s why Waymos stop working in any heavy precipitation. As I have said many times, there is a role for LiDAR in some circumstances and I personally oversaw the development of LiDAR for the SpaceX Dragon docking with Space Station. I am well aware of its strengths and weaknesses.”

Tesla’s approach is significantly different than most companies. Waymo, Motional, Aurora, and Zoox all use LiDAR for their self-driving programs, while Tesla continues to rely on its camera-only approach.

Musk even said that Model S and Model X utilized a Tesla-developed high-resolution radar, but it could not “compare to passive optical (cameras), so we turned it off.”

Tesla developed high resolution radar and the hardware is actually present in Model S & X, but it just can’t compare to passive optical (cameras), so we turned it off.

As a side note, any military systems that rely on radar “stealth” technology are toast in a modern conflict,…

Tesla revealed that it has expanded its Robotaxi fleet in Austin, Texas, but has not yet disclosed the exact number of vehicles currently operating as driverless ride-hailing cars in the city.

Before Tesla launched the Robotaxi fleet in Austin on June 22, CEO Elon Musk stated that the fleet would be initially small, comprised of between ten and twenty vehicles in total.

The small fleet size was a way to limit rides and not overwhelm the company as it launched into a new territory: offering driverless rides to those looking to get around Austin. With safety being prioritized, it was understood.

However, there has never been an exact count of the Robotaxi fleet size, and Tesla continues to speak in cryptic fashion, only hinting at what the number of active vehicles could be.

On Tuesday, it expanded its geofence for the third time, increasing the service area in Austin beyond the downtown area and into the suburbs, including the airport and even the Gigafactory Texas.

The size of the geofence is now 173 square miles, up from 91 square miles, which is what it grew to in early August with its second expansion.

The company also said it “increased the number of cars available by 50 percent,” but would not give an exact count:

Skeptics of the Robotaxi platform usually point to two things: the presence of a Safety Monitor in the vehicle and the lack of transparency regarding fleet size.

Tesla has done an excellent job of expanding the service area over the past two months, but it is also expanding the number of people it allows to hail a Robotaxi.

This makes the need for an increased fleet size more imperative.

However, no good reason comes to mind for the company not to tell an exact number, but Tesla has its justifications for it. Grok suggests the Robotaxi fleet could be anywhere from 30 to 75 vehicles in total, but this includes the Bay Area.

Musk did say Tesla is working to get the Bay Area fleet to over 100 vehicles. Hopefully, some clarification regarding fleet size will be provided in the coming weeks or months as the service area in Austin continues to expand.

Elon Musk’s artificial intelligence startup xAI and social media platform X have filed a federal lawsuit against Apple and OpenAI. The suit accuses the companies of violating antitrust rules by limiting competition in the fast-growing AI sector.

The lawsuit

The lawsuit, filed on Monday, challenged Apple’s plan to integrate OpenAI’s ChatGPT into its devices. xAI argued that the partnership gives ChatGPT exclusive first-party access to hundreds of millions of iPhone users worldwide, providing an unfair landscape for competitors in the AI sector.

“As a result of the Apple-OpenAI deal, ChatGPT is not just the default — it is the only generative AI chatbot with a first-party integration into Apple’s smartphones,,” the lawsuit noted. The suit also stated that the deal would give OpenAI “exclusive access to billions of potential prompts.”

Musk’s filing describes the Apple-OpenAI agreement as an “unlawful” arrangement that unfairly disadvantages rivals and denies consumers choice. The complaint also accuses Apple of manipulating App Store rankings and delaying updates to disadvantage ChatGPT’s rivals, such as xAI’s very own Grok, as noted in a report from the Financial Times.

A broader feud

Musk’s move escalates an already contentious relationship with Apple and OpenAI. In 2022, he accused the iPhone maker of threatening to remove Twitter, now X, from its App Store, though he later resolved the “misunderstanding” with Apple CEO Tim Cook. 

In 2023, Apple briefly paused advertising on X before resuming campaigns. Musk has also been outspoken against Apple’s 30% App Store commission.

OpenAI, for its part, has dismissed the claims in xAI and X’s lawsuit. In a comment, a spokesperson from the artificial intelligence startup stated that the suit was just part of Elon Musk’s tendency to harass the company. 

“This latest filing is consistent with Mr Musk’s ongoing pattern of harassment,” the OpenAI spokesperson stated.

Musk has had a turbulent relationship with OpenAI. Musk is a co-founder of the startup when it was launched as a nonprofit, though he left its board in 2018. Since then, Musk has been very critical of OpenAI’s shift to a for-profit entity. He has also escalated his rhetoric against OpenAI CEO Sam Altman, whom he has called a “liar” several times.
