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.”

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.

Tesla Roadster event gets delayed due to unfavorable weather

Published

Credit: Tesla

Tesla is delaying its event for the Roadster, moving it from this Thursday, October 1, to Thursday, October 15, due to unfavorable weather.

The company has said it has been tracking the weather for this Thursday closely with local meteorologists, and because the event can only be held outside, Tesla is making the call to delay it:

“We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule. New date is October 15. Additional details to follow.”

We are sure that this is bringing back PTSD for some Tesla fans, and we know it is not ideal, but this also reveals some things about the event. Tesla said that this can only be held outdoors, meaning it bodes well for the rumors that the vehicle could potentially hover.

Some believe that this was essentially confirmed by the FAA airspace restriction they were granted, but this could have been for a drone show or to keep drones from spying on the event.

Tesla Roadster is available for order once again following brief hold

The Roadster event has been long-awaited, and it is unfortunate that the weather is going to keep us all waiting a little bit longer.

The Tesla Roadster will be unveiled in Waco, Texas.

SpaceX turned a heralding moment for Starship into its greatest

Starship reached orbit despite losing an engine, deployed 26 Starlink V3 satellites on Flight 14.

SpaceX’s Starship reached orbit for the first time on Monday, and for a few nail-biting minutes it looked like it wouldn’t. During ascent on Flight 14, one of Ship 41’s six Raptor engines shut down early, and SpaceX’s livestream host Dan Huot told viewers the team had decided not to commit to orbit. Minutes later, after what Huot described as a lot of conversation in the control room, the final poll came back in favor, and a roughly 19 second burn of a single Raptor pushed the ship into orbit about 170 miles up.

The reversal matters because SpaceX had written the exit ramp into the mission plan. The company said it would only fire the orbital insertion burn if flight controllers confirmed enough backup hardware remained for the deorbit burn, a condition Teslarati laid out ahead of the flight. Losing an engine was exactly the scenario that rule was built for.

Pressing forward fits Elon Musk’s history. Falcon 1 failed three straight times before its fourth launch reached orbit in 2008, with SpaceX nearly out of money, and Starship was developed by flying prototypes until they broke. What changed this year SpaceX going public, and with $SPCX sliding below its IPO price in July when Flight 13 slipped, the short interest climbed significantly, as Teslarati reported at the time. A Starship potentially lost today with revenue generating next-gen Starlink satellites aboard would have landed directly on shareholders.

That pressure showed up after orbit. SpaceX cut a flight planned to last nearly 10 hours to about three, moving splashdown from west of Chile to the North Pacific near Hawaii. SpaceX gave no reason, though Musk said this month the company was being extremely cautious about debris risk. The single Raptor for deorbit worked, and Ship 41 completed its flip and landing burn before breaking apart in the water, an outcome SpaceX expected. Musk has structured SpaceX’s governance to shield long term bets from market pressure.

The payload is the bigger business story. Musk posted that all 26 Starlink V3 satellites deployed and are “operating nominally.” Each V3 is rated for about 1 Tbps of downlink and 160 Gbps of uplink, so this single launch adds roughly 26 Tbps, about 10 times what a Falcon 9 load of V2 Mini satellites adds. The V3 is too large for Falcon 9, making Starship the only vehicle that can build out the planned 100,000 satellite constellation, at up to 60 per flight once it reaches routine service. Unlike the 20 V3 units on Flight 13, which reentered on a suborbital path, these will raise their orbits and could begin serving customers within weeks and bring in hundreds of millions of additional dollars in projected Starlink revenue.

SpaceX has already begun winding down Falcon 9 Starlink launches from Florida in favor of Starship. Reported targets put Flight 15 as early as October 19, leaving about three weeks to diagnose Monday’s engine shutdown before the next orbital attempt.

Tesla Cybercab fleet doubles to well over 100 units

Tesla quietly doubled the size of its Cybercab fleet within the Robotaxi program in Austin, Texas, over the weekend to well over 100 units.

The move not only establishes more of the steering-wheel-less and pedal-less vehicles within the ride-sharing fleet Tesla has been operating for a year, but it also solidifies a more robust Robotaxi fleet as a whole.

Riders started receiving notifications from the Robotaxi app that stated: “Cybercab fleet has doubled: more rides available.”

Tesla first launched rides in the Cybercab in early September, although the Robotaxi fleet has been active for over a year, as rides began last Summer. Cybercab is truly Tesla’s most crucial vehicle release yet, as it is the first car any company has built that is geared toward full-fledged and end-to-end autonomy, never needing human intervention for anything.

Only available in Austin at the current time, Cybercab has two seats and has been spotted testing around various U.S. states and regions; Tesla plans to deploy the Cybercab in various U.S. cities in the coming months as a best-case scenario.

Tesla Cybercab gets initial tie-in to localized, in-house cathode plant

The availability of the Cybercab has doubled from just 58 units last Monday to 125 the following Friday. Marking a substantial increase in Cybercab availability, the additional ride-sharing units are more than welcome, as wait times for Cybercabs, especially, were quite high.

The dramatic increase is a sign that demand for Robotaxi is growing and Tesla is feeling more confident that its driverless ride-hailing suite, especially its Full Self-Driving software, is able to handle any traffic situation without explicit direction or supervision from a human being.
