To say that the Tesla Semi ruffled some feathers when it was unveiled last year is an understatement. Prior to the reveal of all-electric truck, questions were abounding about its viability as an alternative to conventional diesel-powered long-haulers. Even after the Semi’s specs and performance were announced, the vehicle still attracted a lot of skepticism.

During an event for Daimler’s e-Actos electric truck, for example, the company’s Head of Trucks, Martin Daum, noted that Elon Musk’s claims about the Semi’s 300 and 500-mile range are farfetched. Citing limitations in battery tech, Daum stated that “If Tesla really delivers on this promise, we’ll obviously buy two trucks — one to take apart and one to test because if that happens, something has passed us by. But for now, the same laws of physics apply in Germany and in California.” Jon Mills, a spokesman for engine maker Cummins Inc. noted back in August that while electrification is in the future of the trucking industry, the vehicles are not viable in their current state.  

Since it was unveiled, the Tesla Semi has been spotted traveling across the United States. Tesla unveiled two working prototypes of the Semi – one painted silver and the other matte black – when it unveiled the vehicle, and so far, both have been spotted testing on US roads. Both trucks were also sighted delivering cargo from Gigafactory 1 in NV to the Fremont factory in CA. Most recently, the silver Tesla Semi was sighted in Gigafactory 1, hauling a trailer and seemingly ready to transport cargo.

Tesla is not the only manufacturer coming up with a zero-emissions truck. As the transport industry starts accelerating its shift towards electrification, even prominent truck companies are coming up with their own green vehicles. Most of these vehicles exist as concepts for now, but they do give an idea of how veteran truckmakers are approaching the industry’s transition to the electric age.

Ford, for one, recently revealed the F-Vision concept, which is loaded to the teeth with cutting-edge tech, including an adaptable windshield that can lower and rise depending on the driver’s preference, as well as front lights that can be fully customized. Last month, Volvo introduced the Vera, its next-generation semi-trailer concept. Unlike Tesla and Ford’s truck, Volvo’s vehicle does not even have a driver’s cabin, as it is designed fully for autonomy. Startup trucking companies are also showcasing their offerings. Nikola Motors, for one, made headlines when it unveiled its long-range sleeper hydrogen-electric truck – the Nikola One – back in December 2016, and the company has since teased its next offering, a day cab called the Nikola Two.

There is little doubt that the upcoming electric truck concepts that have been unveiled so far are exciting vehicles in their own right. Inasmuch as this is the case, though, many of these impressive concepts feature technology that is still yet to be developed or refined. During the F-Vision’s unveiling, for one, Ford clarified that the truck is strictly a concept for now. Volvo’s Vera is a perfect fit for short-haul trips thanks to its 300 kWh battery that gives it a 187-mile range, but the vehicle can’t be deployed anytime soon since self-driving tech is still under development (even autonomous tech leader Waymo is reportedly struggling with its fleet’s real-world testing). Nikola’s hydrogen-electric trucks are powerful and boast long-range, but they would need a network of H2 refilling stations before they can be a viable alternative to diesel trucks. As a result, most zero-emissions truck concepts, including the Nikola One prototype, are yet to be sighted doing real-world tests on public roads. 

This is where the Tesla Semi is different. Among the upcoming electric trucks in the market, the Semi is the one undergoing consistent, intensive real-world testing. The vehicle has been spotted in multiple states since its unveiling, at times even visiting the sites of reservation holders like UPS, J.B. Hunt and PepsiCo. As it conducts its extensive real-world tests, the vehicle undergoes a consistent process of improvement. This was highlighted by Tesla’s Head of Automotive Jerome Guillen during the Q2 2018 earnings call, when he stated that several improvements have already been introduced to the electric truck since it was unveiled last year. Elon Musk even teased on Twitter that the Semi would likely have closer to 600 miles of range per charge. With this, it seems safe to infer that the production version of the Tesla Semi would be better than the prototype that is currently traveling across the country today. 

The Tesla Semi balances its features without overdoing it as well. It does not have the cloud-based autonomy of concepts like the Vera or the flashy variable front design of the Ford F-Vision, but ultimately, it does not need to have all these extra bells and whistles to become effective at what it’s designed to do. Tesla created the Semi to be a viable alternative to diesel-powered long-haulers, and if recent sightings and its consistent road tests is any indication, it appears that the vehicle is poised to be exactly that.

The Tesla Semi is expected to start production sometime in 2019. Recent reports have indicated that Tesla is planning on “earnestly” producing the Semi sometime in 2020.

Tesla has improved Dashcam playback with an awesome new addition, as the company has launched a web-based version that is potentially easier to navigate and operate.

The tool is available at dashcam.tesla.com and will be enabled as your vehicle receives the 2026.20 Software Version. Clips that are captured by your Tesla will be available on the Online Dashcam Clip Viewer once the files on your car’s storage drive are encrypted.

Not a Tesla App first noticed the new feature, and states that once your Tesla updates to 2026.20, the car will automatically protect the clips with an encryption key that is uniquely tied to your owner account.

The web-based viewer should be easier to operate for most. All you will do is head over to dashcam.tesla.com and log in using your account credentials.

Ensure your vehicle is updated to 2026.20 in order for the web-based viewer tool to fetch your vehicle’s saved dashcam clips.

Currently, only a small percentage of owners are updated to this, so it may be a couple of weeks until a majority of owners in the fleet are able to access this feature.

Watching Dashcam clips on the Tesla smartphone app is quick and convenient, as they can also be easily downloaded and stored right on your smartphone.

However, the clips are sometimes tougher to navigate, and in order to get details like self-driving activation, speed, and turn signals, owners have to screen record the Tesla app and crop out the rest of the screen.

It could also be a massive storage saver as you’ll be able to download the Dashcam clips from the online viewer and save them to your laptop, desktop, a flash drive, or even an external hard drive. This will keep all your clips in one place.

Tesla Full Self-Driving attempts 150-mile stress test: the good and the bad

I recently took my Tesla Model Y running Full Self-Driving (Supervised) v14.3.3 over 150 miles on the Pennsylvania Turnpike in an effort to truly put the system under a stress test. There were a lot of good moments, and some bad, but overall, Full Self-Driving impressed me.

Last Thursday, I decided it was time to visit the Flight 93 National Memorial near Shanksville, PA. I go a few times a year, and it was a beautiful day. Others have taken some pretty lengthy drives using FSD, but I haven’t had the opportunity to really do something lengthy in quite a few months on an older version. I decided it was the perfect opportunity to try some things out.

I recorded the entire ride there on a GoPro, edited to highlight the crucial moments, and shared them on our social media accounts. If you want to watch them, I’ll share them throughout the piece, but I did not get to do a real breakdown of what I felt about its performance.

Overall Thoughts

I realize it is probably better to do a summation of its performance toward the end of the piece, but I feel like it is also reasonable to lead with this because I was overly impressed with how well it handled everything. The only moments where I felt a little bit of reason to touch the wheel, at least while traveling on the Turnpike and Rt. 30, were due to other drivers and their behaviors.

I have taken many drives to the Memorial over the past several years, and although it’s not incredibly long, it is a tiring drive. It’s about five hours both ways, close to 300 miles, and I think most of the exhaustion comes from the toll of sitting in the car and then visiting something that is pretty heavy to take in.

This was the first time I’ve ever taken the ride and not felt like I needed to avoid my vehicle after I got home. In the past, I could not even think about driving after I finally arrived at my house, but this was simply different.

It was nice to have something else take the drive for me, while I still had the freedom to take over if I chose to. It made the entire trip more enjoyable.

Full Self-Driving Recognizes Lane-Ending Arrows on Road

After traveling in the fast lane for a little while, FSD noticed the arrows on the road indicating the lane was coming to an end ahead. The car was also in the process of making a pass on a slower vehicle in the middle lane, but aborted this maneuver and backed off to get behind the vehicle.

I was really impressed by this because I thought that the car would absolutely try to make the pass, only to get in front of the other car, and then slow back down to 75 MPH:

Full Self-Driving Notices Veering Tractor Trailer, Adjusts Lane Positioning

My two rules of the road are never cruise in the fast lane and never drive next to a tractor-trailer. This clip is a perfect example as to why.

FSD v14.3.3 recognized this tractor-trailer attempting to change lanes while we were still next to it. The car shifted its lane positioning to the shoulder slightly to make room for the merging semi, executed the pass safely, and on we went.

I will admit this one made me a little nervous, but more so because of the 18-wheeler, and not because of the Tesla:

Full Self-Driving Follows the Rules of Tunnel Travel

Many people who are not familiar with Full Self-Driving and its capabilities are pretty limited in what they know about the really simple things it does well. Part of supervising FSD is being aware of things it might make mistakes with, and anticipating maneuvers it might want to make at the wrong time.

Entering the Blue Mountain Tunnel on the Turnpike, I was ready for FSD to attempt to get back into the right lane after making a pass on a tractor-trailer, but I was pleasantly surprised. Several signs outside the tunnel advise drivers to stay in the lane they’ve chosen while driving through the tunnel; this eliminates the possibility of an accident caused by lane changes, which would impede traffic on a crucial logistics route.

I was happy to see that Tesla Full Self-Driving v14.3.3 did not make this mistake:

Full Self-Driving Navigates Toll Plazas with Ease

I was interested to see how FSD would handle toll plazas, including the speed at which it would travel through them, and whether it would stop on the Turnpike at these booths, which have since been transitioned to a “Toll by Plate” system, which mails you a bill.

It was flawless:

Full Self-Driving Still Struggles with Parking from Time to Time

Since I took delivery in late August, I’ve never had a single instance of my Tesla struggling to park at a Supercharger. Other spots at the mall, market, or gym are another story.

This was the first time it did such a terrible job of backing into a spot. This required me to take over and manually park at another charger:

Full Self-Driving Gets Confused After Arriving at Its Destination

This was the first time I have ever experienced FSD getting confused and just circling the lot. The navigation continued to reroute to try to resolve the issue, but after four laps, I decided it was time to overtake the car’s controls and park manually:

This was a baffling behavior that I truly couldn’t explain. Other owners communicated that they have also experienced this issue.

Final Thoughts

I am so incredibly impressed by FSD that it has really made traveling stress-free. The two issues related to parking were not ideal, but to be fair, I usually take over when arriving at parking lots. However, this shortcoming is something Tesla has to make some serious progress with, because parking has truly stumped FSD at times.

Solving that will be a major breakthrough for autonomy, but Tesla has struggled with it for some time.

All in all, FSD v14.3.3 is unbelievably accurate and handles many of the more stressful maneuvers with ease, one of them being avoiding merging traffic on highways, which was shown above.

Some things that would be great to see improvements on are parking, Speed Profiles, which are relatively tough to adjust (I stayed in Standard for the duration of this drive), and, of course, navigation.

SpaceX’s amended S-1 is sparking a major Tesla merger conversation

A single line in SpaceX’s amended S-1 just sent Tesla stock down 5% in one day.

A single line buried in SpaceX’s amended S-1 filing is doing more to move Tesla’s stock price than anything Tesla itself has announced in months. The clause, disclosed as SpaceX prepares for what could be the largest IPO in Wall Street history, states that the company “may issue a significant amount of equity in connection with future transactions.” While this may be seen as boilerplate language in S-1 filings, the historical ties between SpaceX and Tesla, and with Elon Musk reportedly discussing a possible merger with close colleagues, investors are interpreting it as something closer to a signal.

The concern among institutional investors like Gary Black, managing director of The Future Fund, pointed directly to the amended filing on X, saying it “strongly suggests more SPCX equity will be issued,” which could potentially be used to acquire Tesla. He estimated such a deal could be 28% dilutive to Tesla shareholders since SpaceX would likely command a significantly higher valuation multiple. Black added that institutional investors he knows hate the idea of a combination because they prefer pure plays over conglomerates, which he said “nearly always gravitate to the lowest common multiple.”

The Tesla and SpaceX merger everyone is talking about is quietly building

The bull case runs the math differently. Tesla influencer and retail shareholder advocate AleXandra Merz pushed back on what she called a widespread misunderstanding of how merger-of-equals deals actually work. Rather than simply splitting the difference between two market caps, a merger exchange ratio is negotiated based on relative fair market values, meaning the lower valued company typically sees its stock reprice upward toward the deal value.

Under her model, SpaceX enters at a $2.5 trillion valuation and Tesla at $1.6 trillion, producing a combined entity worth $4.1 trillion split evenly between both shareholder groups. That implies Tesla’s side of the deal would be valued at $2.05 trillion, a gain of roughly $450 billion from its current market cap. She cited Dow-DuPont and CBS-Viacom as historical examples of how markets reprice both companies toward the announced exchange ratio after a deal is unveiled.


The SpaceX S-1 amendments also revealed just how much financial infrastructure already binds the two companies together. As Teslarati has reported, SpaceX purchased $697 million in Tesla Megapacks, $131 million in Cybertrucks, and the two companies have shared supply chain resources, and semiconductor fabrication plans since well before any merger conversation became public. A retail poll by Tesla influencer Sawyer Merritt is finding that 36% of respondents do not plan to buy SpaceX shares at IPO and 15.3% saying their decision depends on the valuation.


Whether the merger happens or not, the amended filing is seemingly moving markets and sharpened a debate that is no longer theoretical. SpaceX is weeks away from trading publicly, and Tesla shareholders are now watching every word of every filing for clues about what Musk plans to do next.
