Tesla owners convey worries over radar loss for inclement weather
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 owners propose interesting theory about Apple CarPlay and EV tax credit
“100%. It’s needed for sales because for many prospective buyers, CarPlay is a nonnegotiable must-have. If they knew how good the Tesla UI is, they wouldn’t think they need CarPlay,” one owner said.
Tesla is reportedly bracing for the integration of Apple’s well-known iOS automotive platform, CarPlay, into its vehicles after the company had avoided it for years.
However, now that it’s here, owners are more than clear that they do not want it, and they have their theories about why it’s on its way. Some believe it might have to do with the EV tax credit, or rather, the loss of it.
Owners are more interested in why Tesla is doing this now, especially considering that so many have been outspoken about the fact that they would not use it in favor of the company’s user interface (UI), which is extremely well done.
After Bloomberg reported that Tesla was working on Apple CarPlay integration, the reactions immediately started pouring in. From my perspective, having used both Apple CarPlay in two previous vehicles and going to Tesla’s in-house UI in my Model Y, both platforms definitely have their advantages.
However, Tesla’s UI just works with its vehicles, as it is intuitive and well-engineered for its cars specifically. Apple CarPlay was always good, but it was buggy at times, which could be attributed to the vehicle and not the software, and not as user-friendly, but that is subjective.
Nevertheless, upon the release of Bloomberg’s report, people immediately challenged the need for it:
Everyone thinks they need it. I would think that too if I didn’t know how good Tesla’s interface was. CarPlay is a crappy layer on top of crappy info-navs, and people think it’s an imperative because it provides a level of consistency from car to car. They have no clue how much…

How can it not be when the best engineers choose Tesla over Apple and Tesla’s core focus is auto vs Apple being mobile. It’s what Tesla does every day. It’s a side project for Apple. Still Apple is much better than any other auto OEM who attract lesser talent and make digital…

Some fans proposed an interesting point: What if Tesla is using CarPlay as a counter to losing the $7,500 EV tax credit? Perhaps it is an interesting way to attract customers who have not owned a Tesla before but are more interested in having a vehicle equipped with CarPlay?
“100%. It’s needed for sales because for many prospective buyers, CarPlay is a nonnegotiable must-have. If they knew how good the Tesla UI is, they wouldn’t think they need CarPlay,” one owner said.
Tesla has made a handful of moves to attract people to its cars after losing the tax credit. This could be a small but potentially mighty strategy that will pull some carbuyers to Tesla, especially now that the Apple CarPlay box is checked.

Investor's Corner
Ron Baron states Tesla and SpaceX are lifetime investments
Baron, one of Tesla’s longest-standing bulls, reiterated that his personal stake in the company remains fully intact even as volatility pressures the broader market.
Billionaire investor Ron Baron says he isn’t touching a single share of his personal Tesla holdings despite the recent selloff in the tech sector. Baron, one of Tesla’s longest-standing bulls, reiterated that his personal stake in the company remains fully intact even as volatility pressures the broader market.
Baron doubles down on Tesla
Speaking on CNBC’s Squawk Box, Baron stated that he is largely unfazed by the market downturn, describing his approach during the selloff as simply “looking” for opportunities. He emphasized that Tesla remains the centerpiece of his long-term strategy, recalling that although Baron Funds once sold 30% of its Tesla position due to client pressure, he personally refused to trim any of his personal holdings.
“We sold 30% for clients. I did not sell personally a single share,” he said. Baron’s exposure highlighted this stance, stating that roughly 40% of his personal net worth is invested in Tesla alone. The legendary investor stated that he has already made about $8 billion from Tesla from an investment of $400 million when he started, and believes that figure could rise fivefold over the next decade as the company scales its technology, manufacturing, and autonomy roadmap.
A lifelong investment
Baron’s commitment extends beyond Tesla. He stated that he also holds about 25% of his personal wealth in SpaceX and another 35% in Baron mutual funds, creating a highly concentrated portfolio built around Elon Musk–led companies. During the interview, Baron revisited a decades-old promise he made to his fund’s board when he sought approval to invest in publicly traded companies.
“I told the board, ‘If you let me invest a certain amount of money, then I will promise that I won’t sell any of my stock. I will be the last person out of the stock,’” he said. “I will not sell a single share of my shares until my clients sold 100% of their shares. … And I don’t expect to sell in my lifetime Tesla or SpaceX.”

Tesla CEO Elon Musk responds to Waymo’s 2,500-fleet milestone
While Tesla’s Robotaxi network is not yet on Waymo’s scale, Elon Musk has announced a number of aggressive targets for the service.
Elon Musk reacted sharply to Waymo’s latest milestone after the autonomous driving company revealed its fleet had grown to 2,500 robotaxis across five major U.S. regions.
As per Musk, the milestone is notable, but the numbers could still be improved.
“Rookie numbers”
Waymo disclosed that its current robotaxi fleet includes 1,000 vehicles in the San Francisco Bay Area, 700 in Los Angeles, 500 in Phoenix, 200 in Austin, and 100 in Atlanta, bringing the total to 2,500 units.
When industry watcher Sawyer Merritt shared the numbers on X, Musk replied with a two-word jab: “Rookie numbers,” he wrote in a post on X, highlighting Tesla’s intention to challenge and overtake Waymo’s scale with its own Robotaxi fleet.
While Tesla’s Robotaxi network is not yet on Waymo’s scale, Elon Musk has announced a number of aggressive targets for the service. During the third quarter earnings call, he confirmed that the company expects to remove safety drivers from large parts of Austin by year-end, marking the biggest operational step forward for Tesla’s autonomous program to date.
Tesla targets major Robotaxi expansions
Tesla’s Robotaxi pilot remains in its early phases, but Musk recently revealed that major deployments are coming soon. During his appearance on the All-In podcast, Musk said Tesla is pushing to scale its autonomous fleet to 1,000 cars in the Bay Area and 500 cars in Austin by the end of the year.
“We’re scaling up the number of cars to, what happens if you have a thousand cars? Probably we’ll have a thousand cars or more in the Bay Area by the end of this year, probably 500 or more in the greater Austin area,” Musk said.
With just two months left in Q4 2025, Tesla’s autonomous driving teams will face a compressed timeline to hit those targets. Musk, however, has maintained that Robotaxi growth is central to Tesla’s valuation and long-term competitiveness.
