Does Tesla have a fair chance after NTSB Chief comments?

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.


Earlier this week, NTSB Chief Jennifer Homendy made some disparaging comments regarding Tesla’s use of “Full Self-Driving” to explain its semi-autonomous driving suite. The remarks from Homendy show that Tesla may not have a fair chance when it ultimately comes to proving the effectiveness of its FSD program, especially considering agency officials, who should remain impartial, are already making misdirected comments regarding the name of the suite.

In an interview with the Wall Street Journal, Homendy commented on the company’s use of the phrase “Full Self-Driving.” While Tesla’s FSD suite is admittedly not capable of Level 5 autonomy, the idea for the program is to eventually roll out a fully autonomous driving program for those who choose to invest in the company’s software. However, instead of focusing on the program’s effectiveness and commending Tesla, arguably the leader in self-driving developments, Homendy concentrates on the terminology.

Homendy said Tesla’s use of the term “Full Self-Driving” was “misleading and irresponsible,” despite the company confirming with each driver who buys the capability that the program is not yet fully autonomous. Drivers are explicitly told to remain vigilant and keep their hands on the wheel at all times. It is a requirement to use Autopilot or FSD, and failure to do so can result in being locked in “Autopilot jail” for the duration of your trip. Nobody wants that.

However, despite the way some media outlets and others describe Tesla’s FSD program, the company’s semi-autonomous driving functionalities are extraordinarily safe and among the most complex on the market. Tesla is one of the few companies attempting to solve the riddle that is self-driving, and the only to my knowledge that has chosen not to use LiDAR in its efforts. Additionally, Tesla ditched radar just a few months ago in the Model Y and Model 3, meaning cameras are the only infrastructure the company plans to use to keep its cars moving. Several drivers have reported improvements due to the lack of radar.

These comments regarding FSD and Autopilot are simple: The terminology is not the focus; the facts are. The truth is, Tesla Autopilot recorded one of its safest quarters, according to the most recently released statistics that outlined an accident occurring on Autopilot just once every 4.19 million miles. The national average is 484,000 miles, the NHTSA says.

It isn’t to say that things don’t happen. Accidents on Autopilot and FSD do occur, and the NHTSA is currently probing twelve incidents that have shown Autopilot to be active during an accident. While the conditions and situations vary in each accident, several have already been proven to be the result of driver negligence, including a few that had drivers operating a vehicle without a license or under the influence of alcohol. Now, remind me: When a BMW driver is drunk and crashes into someone, do we blame BMW? I’ll let that rhetorical question sink in.

Of course, Homendy has a Constitutional right to say whatever is on her mind. It is perfectly reasonable to be skeptical of self-driving systems. I’ll admit, the first time I experienced one, I was not a fan, but it wasn’t because I didn’t trust it. It was because I was familiar with controlling a vehicle and not having it manage things for me. However, just like anything else, I adjusted and got used to the idea, eventually becoming accustomed to the new feelings and sensations of having my car assist me in navigating to my destination.

To me, it is simply unfortunate for an NTSB official to claim that Tesla “has clearly misled numerous people to misuse and abuse technology.” One, because it isn’t possible, two, because it would be a massive liability for the company, and three, because Tesla has never maintained that its cars can drive themselves. Tesla has never claimed that its cars can drive themselves, nor has Tesla ever advised a driver to attempt a fully autonomous trek to a destination.

The numerous safety features and additions to the FSD suite have only solidified Tesla’s position as one of the safest car companies out there. With in-cabin cameras to test driver attentiveness and numerous other safety thresholds that drivers must respond to with the correct behaviors, Tesla’s FSD suite and its Autopilot program are among the safest around. It isn’t favorable for NTSB head Homendy to comment in this way, especially as it seems to be detrimental to not only Tesla’s attempts to achieve Level 5 autonomy but the entire self-driving effort as a whole.

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

Why Tesla Roadster unveiling delay might have nothing to do with it flying

Published

on

Tesla announced on Monday that the Roadster event scheduled for today would be postponed due to the need for it to be held outside.

Less than 24 hours later, CEO Elon Musk broadened that by stating it was due to high winds, immediately sending everyone into a frenzy over the Roadster’s potential ability to fly.

And realistically, it could definitely have to do with it flying, hovering, or hopping; whatever Tesla has in mind for this demonstration could not be impacted by wind. However, it might have nothing to do with the vehicle flying whatsoever, and instead could be a simple precaution, as the Roadster is a very unique vehicle with some already official specs that are just mind-blowing.

Tesla will very, very likely be showcasing both the acceleration rate and potentially even a top speed demo at the event in Waco. Both of these demonstrations, performed with a vehicle that has such incredibly fast metrics, could easily be impacted by wind as well.

Tesla Roadster event requires restricted airspace, and the FAA obliges

Top Speed Demo

At high speeds, aerodynamic forces are already overwhelmingly present. A crosswind or sudden gust adds a layer of sideways force that the tires must counter with slip angle. On a short demo course, that force can shove the car off the intended line, especially in a light car with a low frontal area and little mass to resist the push.

Electric cars, due to their battery packs, have an advantage of an extremely low center of gravity, giving them extra stability. However, the speeds at which the Roadster could travel at the demo could spell some issues if crosswinds are present.

Gusts are worse than a steady wind because the load changes faster than a driver can smoothly correct. That shows up as weaving or a late correction. Headwinds and tailwinds can also spell disaster. Headwinds cut a measured top speed but raise the power needed to get there or maintain it. Meanwhile, a tailwind can inflate the top speed, and downforce issues could become more noticeable.

Wind also loads the body unevenly. A low car can feel light on the upwind side or see a sudden change in downforce if the gust hits a wing or diffuser at an angle. Tire temperature and pressure might stay near a normal level, but lateral grip can be lost as the vehicle is spent fighting the wind.

Acceleration Demo

Launch and 0-60 MPH runs are shorter, so the car spends less time exposed to forces that could cause things to go awry. However, the first second is very sensitive, as a crosswind at launch could yaw the car before speed builds and prior to aerodynamic impact being too great. The driver will be required to correct traction control or manage how much the wheels are spinning, which will likely be corrected automatically by some sort of traction control system within the Roadster (we are fairly certain Tesla will implement something brilliant with it).

These things could cause an unstable run.

A headwind would increase drag as speed rises, while a tailwind would do the opposite. Meanwhile, surface effects, like wind-driven dust, light debris, or even rain, could reduce grip at the exact moment the tires are asked for peak longitudinal force. Standing water plus a crosswind is a common reason an acceleration attempt might be scrapped.

Flying or Not

No matter what Tesla has in store for the Roadster, waiting for ideal conditions is a great idea. People who follow and support the company, along with the engineers involved in the Roadster program, have been waiting nine years since the last unveiling for this moment. Everything should be ideal.

Some speculate that it’s just not ready, and that’s ridiculous. Why would Tesla even schedule the event — albeit prematurely — after nine years if it was not ready? Why would they jump the gun now?

We were all excited for today, but it truly is the most ideal thing in the world to wait two more weeks so everything, including the weather, can be perfect. The delay is simply worth it. But Tesla, seriously, make this the last one.

SpaceX nails “Lucky 13” astronaut launch, leaning into Tesla tradition and superstition

SpaceX launched Crew-13 astronauts to the ISS Thursday, setting up a record fast Dragon docking.

SpaceX launched NASA’s Crew-13 mission to the International Space Station on Thursday morning, getting four astronauts to orbit despite a forecast of thunderstorms and gusty winds that had threatened to push the flight to Friday.

Falcon 9 lifted off from Space Launch Complex 40 at Cape Canaveral Space Force Station at 11:10 a.m. ET carrying Dragon Grace, NASA confirmed. On board are NASA commander Jessica Watkins, NASA pilot Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov. The first stage booster, B1101, landed at Landing Zone 40 beside the pad on its third flight after previously supporting Crew-12 and a Starlink mission.

It was the first spaceflight for Delaney, Kutryk and Teteryatnikov. Watkins, who flew on Crew-4 in 2022, became the first NASA astronaut to launch aboard a Crew Dragon twice.

Before launch, the crew rode to the pad in Teslas, a tradition on NASA’s SpaceX crew flights since 2020. This time the cars carried specialty plates reading “Lucky 13.” Watkins said the mission patch leans into the number on purpose, as a nod to Apollo 13 and the resilience of that crew.

Grace is now on a short trip to the station. Docking at the forward port of the Harmony module is scheduled for about 7 p.m. ET, roughly 7 hours and 50 minutes after liftoff, which Space.com notes would be the fastest Crew Dragon transit to the ISS yet. Most Dragon flights take around 15 to 24 hours to catch the station. Hatch opening is planned for 8:25 p.m. ET.

The launch came more than two weeks later than originally planned. An oxidizer leak was found in Grace’s propulsion system in August, and NASA and SpaceX added time for tests. That pushed back the return of Crew-12, which has been aboard the station since February and is now set to splash down off Southern California next week. Crew-13 is expected to stay about six months.

SpaceX rescue mission for stranded ISS astronauts nears end — Here’s when they’ll return home

SpaceX already holds NASA orders for crew rotations through Crew-17, while Boeing is preparing an uncrewed Starliner flight to the station as early as December.

Crew-13 was only the first of three SpaceX launches planned for Thursday, as Teslarati previewed on Wednesday. A Falcon 9 launched its Transporter-18 mission from California today, where Google will be launching its first orbital artificial intelligence (AI) test satellite. Meanwhile, Falcon Heavy is set to launch the classified NROL-97 mission for the National Reconnaissance Office from Launch Complex 39A at 11:53 p.m. ET. Its two side boosters will return to Landing Zones 1 and 2, which means Central Florida could hear up to three sonic booms in a single day. The busy stretch follows Starship’s Flight 14 on Monday, which reached orbit for the first time.

Tesla moves forward on Wireless Charging for vehicles

Published

Tesla has moved its Wireless Charging efforts for its electric vehicles forward, as it had a new patent published today, one that it submitted back in March.

The patent describes a system for detecting foreign objects on the wireless charging pad under varying temperatures, aiming to mitigate any undesired results that could come from something being on top of the charging pad.

The abstract of the patent states:

“The present disclosure relates to methods and systems that can reliably detect foreign objects on a wireless charging pad under varying temperatures. In some examples, an object detector can utilize a set of inductive coils included in resonant tanks, and excite the resonant tanks using signals in a range of frequencies including or near a nominal resonant frequency of the resonant tanks. The object detector can detect a metal object based on resistance of a coil increasing and inductance of the coil decreasing. By analyzing the shifts and/or distributions in resonant frequencies and output magnitudes (e.g., output voltage peaks), the object detector can distinguish between changes of frequencies and magnitudes caused by temperature and those caused by foreign objects to accurately detect the foreign objects.”

The object detection system will utilize a set of inductive coils included in resonant tanks, and “excite the resonant tank using signals in a range of frequencies including or near a nominal resonant frequency of the tanks.” Metal can be detected by an increase in the coil’s resistance and a decrease in the coil’s inductance.

By analyzing shifts or disruptions in resonant frequencies and output magnitudes, the system can detect foreign objects. These types of safeguards need to be implemented through the normal operation of the charging pads.

Tesla says its Cybercab wireless charging efficiency is ‘well above 90%’

Tesla plans to utilize wireless charging with Cybercab and Robotaxi-enabled units to help streamline the fully autonomous experience from A to Z. The last thing the company wants to do is have any sort of small obstruction preventing the rider from experiencing Robotaxi as intended.
