On September 17th, a NASA blog post praised the progress SpaceX has made with Crew Dragon’s parachute system, indicating that the company is actually pushing the state of the art forward with improved modeling after dozens of tests.

Both before and after SpaceX completed Crew Dragon’s flawless March 2019 orbital launch debut, both NASA and the agency’s Aerospace Safety Advisory Panel (ASAP) have relentlessly focused on two main concerns: Falcon 9’s COPVs and Crew Dragon’s parachutes. The reasoning behind that focus is logical but may pose some problems.

Assuming that discussion points raised during quarterly ASAP and NASA Advisory Council (NAC) meetings are an accurate external representation of NASA’s internal Commercial Crew Program (CCP) priorities, the space agency has been focused on parachutes and COPVs for years. This is primarily a result of NASA’s notoriously reactive approach to safety: SpaceX suffered two COPV-related Falcon 9 failures in 2015 and 2016 and has experienced an unknown number (likely 1-3) of anomalies during Crew Dragon parachute testing.

As a result, NASA has focused extensively on these two stand-out concerns. To an extent, this is reasonable – if you know things have a tendency to fail, you’re going to want to make sure that they don’t. However, prioritizing reactive safety measures at the cost of proactive safety would be a major risk, akin to getting in a car crash because you didn’t use a turn signal and then prioritizing turn signal use so much that you forget to look both ways before making turns. Sure, you will probably never get in the same crash, but you are raising the risk of new kinds of accidents if you overcorrect your attention distribution.

NASA infamously suffered from this throughout the Space Shuttle program, analyzing known-quantities into oblivion as systematic organizational failures and glaring (but new) design flaws were either ignored or buried until it was far too late. It’s impossible to say if NASA is repeating this apparently deep-seated organizational error with Commercial Crew – only the technical experts at SpaceX and NASA have the data to accurately judge. It can be said with certainty, however, that the space agency (and its advisory panels) completely failed to predict the failure mode(s) that caused an April 20th Crew Dragon explosion that would have almost certainly killed all aboard, all while COPVs and parachutes continue(d) to be the apparent focus.

Pushing the envelope of parachute design

Qualms aside, NASA’s September 17th blog does serve as a unique look into the benefits that the space agency’s prioritization of the obvious – for better or for worse – is producing. According to NASA, the incredibly extensive testing SpaceX has had to do to satisfy agency requirements has lead the company to develop “a better understanding of how to safely design and operate parachute clusters”. SpaceX has reportedly completed 48 distinct parachute tests, of which one or two apparently failed.

In response to the additional testing and analysis NASA required after a recent April 2019 test failure, SpaceX has essentially been forced to push the state of the art of parachute design and modeling to new levels. NASA says that SpaceX has begun to model certain conditions and newfound failure modes in ways that “provide a better understanding of parachute reliability” and have forced NASA to reevaluate its own standards and certification processes. Shown in the video above, SpaceX recently completed a successful second attempt of its failed April 2019 parachute test, a major step towards confirming that the new parachute analysis and design have mitigated prior faults.

Tesla plant manager tips off affordable model production

A plant manager at a Tesla factory just tipped off the fact that the company will begin production of an affordable model in the coming weeks, all but confirming that a new car will be unveiled tomorrow.

Tesla has been teasing some kind of product unveiling for October 7 on its social media accounts. It has now dropped two separate indications that a new product is coming on its X account.

Fans have been anticipating two things: either the company’s planned affordable model, which has been codenamed “E41,” or the Roadster, a long-awaited vehicle that Tesla has kept under wraps for much longer than it would likely care to admit.

Tesla all but confirms that affordable Model Y is coming Tuesday

André Thierig, Tesla’s plant manager at the German production plant Gigafactory Berlin, tipped off what is likely coming tomorrow at the product unveiling as he revealed during an internal event today that a light version of the Model Y will begin series production and deliveries “in a few weeks.”

Thierig’s revealing of plans was reported by Handelsblatt, a German media outlet.

The description of a “light version of the Model Y” aligns with what CEO Elon Musk said earlier this year, as well as what we have seen on public roads, both covered and uncovered.

Last week, we finally saw an uncovered version of what the affordable model likely is, as it was cruising around near Gigafactory Texas, just outside of Austin.

Tesla coding shows affordable model details, including potential price

Musk said earlier this year, candidly during an Earnings Call, that the affordable model Tesla planned to release was a Model Y.

“It’s just a Model Y. Let the cat out of the bag there,” Musk said.

The images of what we assumed to be the affordable model lined up with Musk’s candid statement:

Tesla is expected to unveil its affordable model tomorrow during the planned event, which has been teased twice. Pricing and other details are still pending, but the company is expected to reveal this information tomorrow.

Three things Tesla needs to improve with Full Self-Driving v14 release

These are the three things I’d like to see Tesla Full Self-Driving v14 improve.

Published

on

As Tesla plans to release Full Self-Driving version 14 this week after CEO Elon Musk detailed a short delay in its rollout, there are several things that continue to plague what are extremely well-done drives by the suite.

Tesla Full Self-Driving has truly revolutionized the way I travel, and I use it for the majority of my driving. However, it does a few things really poorly, and these issues are consistent across many drives, not just one.

Tesla Full Self-Driving impressions after three weeks of ownership

Musk has called FSD v14 “sentient” and hinted that it would demonstrate drastic improvements from v13. The current version is very good, and it commonly performs some of the more difficult driving tasks well. I have found that it does simple, yet crucial things, somewhat poorly.

These are the three things I’d like to see Tesla Full Self-Driving v14 improve.

Navigation, Routing, and Logical Departure

My biggest complaint is how poorly the navigation system chooses its route of departure. I’ve noticed this specifically from where I Supercharge. The car routinely takes the most illogical route to leave the Supercharger, a path that would require an illegal U-turn to get on the correct route.

I managed to capture this yesterday when leaving the Supercharger to go on a lengthy ride using Full Self-Driving:

You’ll see I overrode the attempt to turn right out of the lot by pushing the turn signal to turn left instead. If you go right, you’ll go around the entire convenience store and end up approaching a traffic light with a “No U-Turn” sign. The car has tried to initiate a U-turn at this light before.

If you’re attempting to get on the highway, you simply have to leave the convenience store on a different route (the one I made the vehicle go in).

It then attempted to enter the right lane when the car needed to remain in the left lane to turn left and access the highway. I manually took over and then reactivated Full Self-Driving when it was in the correct lane.

To achieve Unsupervised Full Self-Driving, such as navigating out of a parking lot and taking the logical route, while also avoiding illegal maneuvers, is incredibly crucial.

Too Much Time in the Left Lane on the Highway

It is illegal to cruise in the left lane on highways in all 50 U.S. states, although certain states enforce it more than others. Colorado, for example, has a law that makes it illegal to drive in the left lane on highways with a speed limit of 65 MPH or greater unless you are passing.

In Florida, it is generally prohibited to use the left lane unless you are passing a slower vehicle.

In Pennsylvania, where I live, cruising in the left lane is illegal on limited-access highways with two or more lanes. Left lanes are designed for passing, while right lanes are intended for cruising.

Full Self-Driving, especially on the “Hurry” drive mode, which drives most realistically, cruises in the left lane, making it in violation of these cruising laws. There are many instances when it has a drastic amount of space between cars in the right lane, and it simply chooses to stay in the left lane:

The clip above is nearly 12 minutes in length without being sped up. In real-time, it had plenty of opportunities to get over and cruise in the left lane. It did not do this until the end of the video.

Tesla should implement a “Preferred Highway Cruising Lane” option for two and three-lane highways, allowing drivers to choose the lane that FSD cruises in.

It also tends to pass vehicles in the slow lane at a speed that is only a mile an hour or two higher than that other car.

This holds up traffic in the left lane; if it is going to overtake a vehicle in the right lane, it needs to do it faster and with more assertiveness. It should not take more than 5-10 seconds to pass a car. Anything longer is disrupting the flow of highway traffic.

Parking

Full Self-Driving does a great job of getting you to your destination, but parking automatically once you’re there has been a pain point.

As I was arriving at my destination, it pulled in directly on top of the line separating two parking spots. It does this frequently when I arrive at my house as well.

Here’s what it looked like yesterday:

Parking is one of the easier tasks Full Self-Driving performs, and Autopark does extremely well when the driver manually chooses the spot. I use Autopark on an almost daily basis.

However, if I do not assist the vehicle in choosing a spot, its performance pulling into spaces is pretty lackluster.

With a lot of hype surrounding v14, Tesla has built up considerable anticipation among owners who want to see FSD perform the easy tasks well. As of now, I believe it does the harder things better than the easy things.

Elon Musk teases previously unknown Tesla Optimus capability

Elon Musk revealed over the weekend that the humanoid robot should be able to utilize Tesla’s dataset for Full Self-Driving (FSD) to operate cars not manufactured by Tesla.

Elon Musk revealed a new capability that Tesla Optimus should have, and it is one that will surely surprise many people, as it falls outside the CEO’s scope of his several companies.

Tesla Optimus is likely going to be the biggest product the company ever develops, and Musk has even predicted that it could make up about 80 percent of the company’s value in the coming years.

Teasing the potential to eliminate any trivial and monotonous tasks from human life, Optimus surely has its appeal.

However, Musk revealed over the weekend that the humanoid robot should be able to utilize Tesla’s dataset for Full Self-Driving (FSD) to operate cars not manufactured by Tesla:

FSD would essentially translate from operation in Tesla vehicles from a driverless perspective to Optimus, allowing FSD to basically be present in any vehicle ever made. Optimus could be similar to a personal chauffeur, as well as an assistant.

Optimus has significant hype behind it, as Tesla has been meticulously refining its capabilities. Along with Musk’s and other executives’ comments about its potential, it’s clear that there is genuine excitement internally.

This past weekend, the company continued to stoke hype behind Optimus by showing a new video of the humanoid robot learning Kung Fu and training with a teacher:

Tesla plans to launch its Gen 3 version of Optimus in the coming months, and although we saw a new-look robot just last month, thanks to a video from Salesforce CEO and Musk’s friend Marc Benioff, we have been told that this was not a look at the company’s new iteration.

Instead, Gen 3’s true design remains a mystery for the general public, but with the improvements between the first two iterations already displayed, we are sure the newest version will be something special.
