This is a preview from our weekly newsletter. Each week I go ‘Beyond the News’ and handcraft a special edition that includes my thoughts on the biggest stories, why it matters, and how it could impact the future.

Tesla’s recent decision to scrap Radar in favor of a Camera-based approach for Autopilot and Full Self-Driving aligned with the company’s plans and statements over the past few Earnings Calls. For CEO Elon Musk, the goal has been to get away from radar and depend on camera systems for Tesla’s self-driving plan, but some owners are not convinced of the decision. Over the past few days, I have received several emails and Tweets about the decision, with some owners still not completely confident in the vision-based approach Tesla will take.

During the Q1 2021 Earnings Call just a few months back, Elon Musk made it clear Tesla would be switching to a Camera-based system for AP and FSD. Comparing the cameras to human eyes, Musk’s explanation made a lot of sense.

Musk said:

“When your vision works, it works better than the best human because it’s like having eight cameras, it’s like having eyes in the back of your head, beside your head, and has three eyes of different focal distances looking forward. This is — and processing it at a speed that is superhuman. There’s no question in my mind that with a pure vision solution, we can make a car that is dramatically safer than the average person.”

Tesla Model 3, Model Y builds in May 2021 will no longer equip radar

Now, the thing is, eyes, while great for seeing things that are in the clear, are highly effective, and it makes a lot of sense to try and use this sort of approach for self-driving because it is how humans have driven for years. But when humans are confronted with low visibility and severe weather on the road, the confidence goes down, and many drivers adjust by traveling at lower speeds. Some even pull over and wait for the weather to subside, a move that is rare for many but some simply do not like driving in bad weather.

This is where radar comes in handy because it can identify and locate objects and how far they are away from the vehicle in the event of low visibility on the road, which is something that the human eyes, or cameras, simply cannot do.

An email from an Australian reader seemed to narrow in this point even further. A man named Peter emailed me and stated that his Model 3 recently identified a truck that was ahead of him but concealed in an opaque, white mist several car links ahead of his vehicle. “I assumed that visualization was created as a result of radar. In those conditions, the message multiple cameras blocked or obstructed appeared and the autopilot screamed and handed over,” Peter said.

He then added, “On multiple other occasions I’ve noted on the visualization screen an unsighted vehicle obstructed by an SUV ahead of me.”

Without radar, the recognition of these vehicles would not be possible, so it brings some concerns to drivers who have utilized the radar system in vehicles to gain confidence in their surroundings.

Now, in a somewhat comical response to concerns, Musk posted a Reddit response from u/YukonBurger, which stated that they worked with radar a lot and were “very, very happy” with Tesla’s decision. It basically explained that trying to jive radar and cameras together is extremely difficult, and there are instances where using your eyes is just a better option because you can see how far you are away from things. Interestingly, the post does admit that “radar is really only good for reduced visibility situations where lane-keeping will probably also be degraded enough to not be worth it.” It concluded by stating that vision is still quick enough to avoid accidents or vehicles in front of the car in a short period of time, the real issue comes from cars behind you.

It seems that the real key to vision being a better approach comes down to the fact that, in clear conditions, it won’t have an issue identifying and removing itself from danger. Even in rainy conditions, where visibility isn’t necessarily bad, the vision approach is more advantageous than using radar.

The goal, ultimately, is to make the cars act as a human would, and humans don’t have radar. Instead, they compensate for reduced visibility with less dangerous driving. Slower speeds, more cautious navigation, and less frequent lane changes. Autopilot and FSD are already pretty timid and “shy” to begin with, it’s not like they’re out there driving like pissed-off teenagers.

I think that, while this move is somewhat worrisome for some drivers, the benefits outweigh the disadvantages. This has been a part of the plan for some time, and I think that now it is becoming a reality, some are starting to put the pieces together that there won’t be any radar so visibility limitations could end up being problematic. I wouldn’t worry, because I believe the cars will adjust just as humans do, they will simply be more cautious and more courteous on the roads in these settings.

A big thanks to our long-time supporters and new subscribers! Thank you.

Tesla Robotaxi test units spotted in new region ahead of launch

These validation units are used to gain additional data for Tesla’s internal use, or even potentially for regulatory purposes that the company can share with agencies that will eventually grant a license to operate Robotaxi in the state.

Tesla Robotaxi test units are being spotted in various new regions ahead of their launch in new states. Tesla is aiming to launch in at least a few new states in the coming months as it is ramping up hiring for the Robotaxi program and aiming to expand its ride-hailing service.

Already active in Austin, Texas, and the California Bay Area, Tesla is looking to expand its Robotaxi operations to new states. It’s had its eyes set on Nevada, Florida, and Arizona, which have seemed to have the most movement of the three prospects over the past month or so.

That trend is continuing.

Earlier this month, we reported on two Robotaxi units spotted testing with LiDAR rigs for ground truth validation in Gilbert, Arizona. Noted Cybertruck owner and enthusiast Greggertruck spotted the two units traveling on a highway.

Now, those same two units, or at least they appear to be, were spotted in Scottsdale, which is also a suburb of Phoenix, like Gilbert is, with the same LiDAR rigs:

These validation units are used to gain additional data for Tesla’s internal use, or even potentially for regulatory purposes that the company can share with agencies that will eventually grant a license to operate Robotaxi in the state.

Tesla is not a company that utilizes LiDAR for its everyday self-driving efforts, as it has utilized only cameras for the past several years.

Tesla Vision, as the company calls it, is what CEO Elon Musk feels is needed to achieve a fully autonomous network of vehicles, which will eventually need zero supervision for passenger transportation.

LiDAR is utilized by other companies, like Waymo, but Tesla has maintained that it is not necessary for several years. Musk has called it a “crutch” for achieving the proper self-driving tech, and the company only uses it for an additional bit of data.

Tesla has been operating its Robotaxi service in Austin since late June, and it has expanded its service area in the city to nearly 300 square miles, with its most recent expansion occurring earlier this week.

Tesla’s popular side business is going to get bigger, Elon Musk says

It took several years to get the Diner developed, built, and opened. On July 21, Tesla launched the Diner to the public at 4:20 p.m. local time (of course), after years of development. Musk first offered the idea of a drive-in Supercharger Diner back in December 2018.

Tesla will open two new Diner locations in the United States after its first location in Los Angeles has been a raging success, as it is constantly packed and serving food for 24 hours a day, every day.

Tesla CEO Elon Musk said that the initial Diner location on Santa Monica Boulevard is “going well,” and based on reviews and its constant out-the-door lines, it is safe to say it has been a major outlet of interest for people in the area.

It features two massive movie screens, a menu that is locally sourced and has been created by a world-class chef, and Supercharging for EVs. It truly is the perfect stop for those who are hungry, need entertainment, or need a quick charge.

So far, Tesla has not released too many details on the success of the restaurant, but it did state in a graphic for its Q3 Supercharging stats that it sold roughly 50,000 burgers at the Diner in Q3, roughly 715 each day. Burgers are not the only thing on the menu, either.

With how well it has gone, Musk is now considering the possibility of new locations that are notable to Tesla, including Austin and Palo Alto.

On Friday, Musk revealed he believes it “probably makes sense to open one” near Gigafactory Texas and Engineering HQ in Palo Alto:”

By 2023, Tesla had secured building permits and broken ground on the site in September of that year.

Since its launch, it has been a popular hotspot for Tesla fans and others to visit, although it has attracted unwanted attention from protestors as well.

They look hungry. If they walked inside and ordered some food, maybe they’d stop yelling into microphones and threatening Musk.

Elon Musk’s AI empire grows as xAI leases Palo Alto space near Tesla

The expanding footprint of Elon Musk’s companies in Palo Alto bodes well for the CEO’s plans in the area.

Elon Musk’s artificial intelligence startup, xAI, is expanding its Silicon Valley footprint, leasing roughly 105,000 square feet of office space at Palo Alto’s Page Mill Center, just blocks away from Tesla’s engineering complex.

Musk’s deepening Silicon Valley footprint

People familiar with the matter have informed the San Francisco Business Times that xAI’s lease at Page Mill Center may already have been finalized, adding to the company’s existing headquarters at 1450 Page Mill Road. The two offices share a parking lot, reflecting Musk’s strategy of consolidating his ventures. Tesla’s engineering hub is also just a few blocks away.

The new offices form a growing cluster of Musk-led companies in the heart of the Valley and come as xAI has listed over 250 job openings. These include listings for engineers, designers, and technical staff, among others. 

xAI’s aggressive hiring push hints at rapid scaling, which makes quite a lot of sense considering the company’s ambitious projects. xAI oversees the large language model Grok and other AI initiatives such as the newly launched Grokipedia, and the startup has also acquired the social media platform X. Real estate owner Hudson Pacific Properties, the owners of Page Mill Center, have so far declined to comment.

AI demand and Silicon Valley’s office rebound

Silicon Valley’s office market, long subdued by remote work trends, is seeing renewed activity from AI firms. Hudson Pacific told investors this summer that tenant demand has reached a three-year high, with over half of new leases driven by artificial intelligence companies. Vacancy rates have now fallen for four straight quarters to 16.6% as well, CBRE reported.

The expanding footprint of Elon Musk’s companies in Palo Alto bodes well for the CEO’s plans in the area. Musk, after all, has previously butted heads with officials, resulting in his two biggest ventures, electric vehicle maker Tesla and private space company SpaceX, officially relocating their headquarters to Texas.
