SpaceX’s full-scale Starship hop debut was aborted at the last second after an otherwise successful lead-up to the milestone, forcing the company to try again tomorrow.

Following a minor delay from August 2nd to August 3rd, SpaceX kicked off Starship SN5’s hop debut preparations relatively late into the 12-hour window, closing the highway and clearing the pad around 5pm CDT (22:00 UTC). The Starship SN5 tank section prototype was pressurized with ambient-temperature gas around the same time, while cryogenic liquid methane and oxygen propellant loading appeared to begin at roughly 6:20pm CDT (23:20 UTC).

Soon after, SpaceX CEO Elon Musk revealed that Starship was just 33 minutes away from launch, marching towards the first hop of a full-scale prototype at 6:56pm CDT. Unfortunately, possibly much less than a second before ignition, Starship SN5’s Raptor engine had different plans.

Musk says that one of Raptor engine SN27’s “spin start valves” failed to open moments before ignition, causing Starship to automatically abort the attempt. With more than an hour left in the window, SpaceX had time to briefly troubleshoot the bug and potentially turn the rocket around for a second attempt, but Musk announced some 50 minutes later that the company would stand down and try again tomorrow.

Musk’s description of the hop test abort sounds suspiciously similar to his description of the last abort of Starship SN5’s Raptor engine static fire test, in which a “fuel spin valve didn’t open.” If the root cause of both aborts is the same, there’s a good chance that SpaceX may need more time to properly investigate and fix the problem. A recurring issue is immediately much more concerning compared to a one-off bug, so there’s also a chance that SpaceX will go as far as replacing the Raptor engine currently installed on Starship SN5.

If things look more severe than SpaceX initially thought they were after the static fire abort and a replacement engine is necessary, Starship SN5 will have to complete another static fire test with the new Raptor before it can proceed to a second hop attempt.

Based on live views of the launch attempt from NASASpaceflight and LabPadre, Starship SN5 likely aborted a matter of milliseconds before Raptor SN27 ignition and perhaps just a second or two before liftoff. Just like SpaceX’s workhorse Falcon 9 and Heavy rockets, the vehicle’s flight computer is fully in control of the countdown a minute or two before liftoff and can automatically abort far faster than any human could possibly react. Held to the launch mount by hold-down clamps, Starship could have technically analyzed the engine’s performance after ignition and aborted the launch even later into the count.

Once hold-down clamp release is commanded, Starship SN5 will attempt to fly a roughly 150m-tall (500 ft) arc heading southeast of the launch mount. Perhaps 10 seconds prior to touchdown, Starship will attempt to deploy an array of six odd legs and gently land a few hundred feet from the pad. As of now, assuming Raptor’s finicky valve can be easily rectified, SpaceX will work towards a second Starship SN5 hop attempt sometime between 8am and 8pm CDT on Tuesday, August 4th.

I subscribed to Tesla Full Self-Driving after four free months: here’s why

It has been incredibly valuable to me, and that is what my main factor was in considering whether to subscribe or not. It has made driving much less stressful and much more enjoyable.

I have been lucky enough to experience Tesla Full Self-Driving for the entire duration of my ownership experience for free — for four months, I have not had to pay for what I feel is the best semi-autonomous driving suite on the market.

Today, my free trial finally ran out, and I had two choices: I could go without it for a period until I felt like I absolutely needed it, or I could subscribe to it, pay $99 per month, and continue to experience the future of passenger transportation.

I chose the latter, here’s why.

Tesla Full Self-Driving Takes the Stress Out of Driving

There are a handful of driving situations that I don’t really enjoy, and I think we all have certain situations that we would just rather not encounter. This is not to say that I won’t ever experience them as someone who has driven a car for 15 years (it feels weird saying that).

I don’t love to drive in cities; I really don’t like driving on I-695 on my way to Baltimore, and I truly hate parallel parking. All three things I can do and have done, all three within the past few weeks, too.

However, if I can avoid them, I will, and Tesla Full Self-Driving does that for me.

Tesla Full Self-Driving Eliminates the Monotony

I drive to my alma mater, Penn State University, frequently in the Winter as I am a season ticket holder to Wrestling and have been for 16 years now.

The drive to State College is over two hours and over 100 miles in total, and the vast majority of it is boring as I travel on Rt 322, which is straight, and there is a lot of nature to look at on the way.

I am willing to let the car drive me on that ride, especially considering it is usually very low traffic, and the vast majority of it is spent on the highway.

The drive, along with several others, is simply a boring ride, where I’d much rather be looking out the windshield and windows at the mountains. I still pay attention, but having the car perform the turns and speed control makes the drive more enjoyable.

Tesla Full Self-Driving Makes Navigating Easier

Other than the local routes that I routinely travel and know like the back of my hand, I’ve really enjoyed Full Self-Driving’s ability to get me to places — specifically new ones — without me having to constantly check back at the Navigation.

Admittedly, I’ve had some qualms with the Nav, especially with some routing and the lack of ability to choose a specific route after starting a drive. For example, it takes a very interesting route to my local Supercharger, one that nobody local to my area would consider.

But there are many times I will go to a new palce and I’m not exactly sure where to go or how to get there. The Navigation, of course, helps with that. However, it is really a luxury to have my car do it for me.

To Conclude

There was no doubt in my mind that when my Full Self-Driving trial was up, I’d be subscribing. It was really a no-brainer. I am more than aware that Full Self-Driving is far from perfect, but it is, without any doubt, the best thing about my Tesla, to me.

It has been incredibly valuable to me, and that is what my main factor was in considering whether to subscribe or not. It has made driving much less stressful and much more enjoyable.

Tesla Diner becomes latest target of gloom and doom narrative

Published

The Tesla Diner has been subject to many points of criticism since its launch in mid-2025, and skeptics and disbelievers claim the company’s latest novel concept is on its way down, but there’s a lot of evidence to state that is not the case.

The piece cites anecdotal evidence like empty parking lots, more staff than customers during a December visit, removed novelty items, like Optimus robot popcorn service and certain menu items, the departure of celebrity chef Eric Greenspan in November 2025, slow service, high prices, and a shift in recent Google/Yelp reviews toward disappointment.

The piece frames this as part of broader Tesla struggles, including sales figures and Elon Musk’s polarizing image, calling it a failed branding exercise rather than a sustainable restaurant.

This narrative is overstated and sensationalized, and is a good representation of coverage on Tesla by today’s media.

Novelty Fade is Normal, Not Failure

Any hyped launch, especially a unique Tesla-branded destination blending dining, Supercharging, and a drive-in theater, naturally sees initial crowds taper off after the “Instagram effect” wears down.

Tesla makes major change at Supercharger Diner amid epic demand

This is common for experiential spots in Los Angeles, especially pop-up attractions or celebrity-backed venues. The article admits early success with massive lines and social media buzz, but treats the return to normal operations as “dying down.”

In reality, this stabilization is a healthy sign of transitioning from hype-driven traffic to steady patronage.

Actual Performance Metrics Contradict “Ghost Town” Claims

  • In Q4 2025, the Diner generated over $1 million in revenue, exceeding the average McDonald’s location
  • It sold over 30,000 burgers and 83,000 fries in that quarter alone. These figures indicate a strong ongoing business, especially for a single-location prototype focused on enhancing Supercharger experiences rather than competing as a mass-market chain

Conflicting On-the-Ground Reports

While the article, and other similar pieces, describe a half-full parking lot and sparse customers during specific off-peak visits, other recent accounts push back:

  • A January 2026 X post noted 50 of 80 Supercharger stalls were busy at 11 a.m., calling it “the busiest diner in Hollywood by close to an order of magnitude

  • Reddit discussions around the same time describe it as not empty when locals drive by regularly, with some calling the empty narrative “disingenuous anti-Tesla slop.”

Bottom Line

The Tesla Diner, admittedly, is not the nonstop circus it was at launch–that was never sustainable or intended. But, it’s far from “dying” or an “empty pit stop.”

It functions as a successful prototype: boosting Supercharger usage, generating solid revenue, and serving as a branded amenity in the high-traffic EV market of Los Angeles.

Tesla stands to win big from potential adjustment to autonomous vehicle limitations

Enabling scale, innovation, and profitability in a sector that is growing quickly would benefit Tesla significantly, especially as it has established itself as a leader.

Tesla stands to be a big winner from a potential easing of limitations on autonomous vehicle development, as the United States government could back off from the restrictions placed on companies developing self-driving car programs.

The U.S. House Energy and Commerce subcommittee will hold a hearing later this month that will aim to accelerate the deployment of autonomous vehicles. There are several key proposals that could impact the development of self-driving cars and potentially accelerate the deployment of this technology across the country.

These key proposals include raising the NHTSA’s exemption cap from 2,500 to 90,000 vehicles per year per automaker, preempting state-level regulations on autonomous vehicle systems, and mandating NHTSA guidelines for calibrating advanced driver assistance systems (ADAS).

Congress, to this point, has been divided on AV rules, with past bills like the 2017 House-passed measure stalling in the Senate. Recent pushes come from automakers urging the Trump administration to act faster amid competition from Chinese companies.

Companies like Tesla, who launched a Robotaxi service in Austin and the Bay Area last year, and Alphabet’s Waymo are highlighted as potential beneficiaries from lighter sanctions on AV development.

The NHTSA recently pledged to adopt a quicker exemption review for autonomous vehicle companies, and supporters of self-driving tech argue this will boost U.S. innovation, while critics are concerned about safety and job risks.

How Tesla Could Benefit from the Proposed Legislation

Tesla, under CEO Elon Musk’s leadership, has positioned itself as a pioneer in autonomous driving technology with its Full Self-Driving software and ambitious Robotaxi plans, including the Cybercab, which was unveiled in late 2024.

The draft legislation under consideration by the U.S. House subcommittee could provide Tesla with significant advantages, potentially transforming its operational and financial landscape.

NHTSA Exemption Cap Increase

First, the proposed increase in the NHTSA exemption cap from 2,500 to 90,000 vehicles annually would allow Tesla to scale up development dramatically.

Currently, regulatory hurdles limit how many fully autonomous vehicles can hit the roads without exhaustive approvals. For Tesla, this means accelerating the rollout of its robotaxi fleet, which Musk envisions as a network of millions of vehicles generating recurring revenue through ride-hailing. With Tesla’s vast existing fleet of over 6 million vehicles equipped with FSD hardware, a higher cap could enable rapid conversion and deployment, turning parked cars into profit centers overnight.

Preempting State Regulations

A united Federal framework would be created if it could preempt State regulations, eliminating the patchwork of rules that currently complicate interstate operations. Tesla has faced scrutiny and restrictions in states like California, especially as it has faced harsh criticism through imposed testing limits.

A federal override of State-level rules would reduce legal battles, compliance costs, and delays, allowing Tesla to expand services nationwide more seamlessly.

This is crucial for Tesla’s growth strategy, as it operates in multiple markets and aims for a coast-to-coast Robotaxi network, competing directly with Waymo’s city-specific expansions.

Bringing Safety Standards to the Present Day

Innovation in the passenger transportation sector has continued to outpace both State and Federal-level legislation, which has caused a lag in the development of many things, most notably, self-driving technology.

Updating these outdated safety standards, especially waiving requirements for steering wheels or mirrors, directly benefits Tesla’s innovative designs. Tesla wanted to ship Cybertruck without side mirrors, but Federal regulations required the company to equip the pickup with them.

Cybercab is also planned to be released without a steering wheel or pedals, and is tailored for full autonomy, but current rules would mandate human-ready features.

Streamlined NHTSA reviews would further expedite approvals, addressing Tesla’s complaints about bureaucratic slowdowns. In a letter written in June to the Trump Administration, automakers, including Tesla, urged faster action, and this legislation could deliver it.

In Summary

This legislation represents a potential regulatory tailwind for Tesla, but it still relies on the government to put forth action to make things easier from a regulatory perspective. Enabling scale, innovation, and profitability in a sector that is growing quickly would benefit Tesla significantly, especially as it has established itself as a leader.
