Tesla Semi mono wiper looks effective in the rain in recent sighting

The Tesla Semi is not like other Class 8 trucks in the market. It’s all-electric, it can travel 500 miles on a single charge, and it’s zero-emissions. It also is equipped with a large mono wiper, which, as per a recent sighting, actually seems to work very well in the rain. 

The video of a new Tesla Semi sighting was recently posted in the r/TeslaMotors subreddit. The short clip seemed to be recorded from a Tesla’s built-in dashcam, and it showed a Tesla Semi wrapped in Frito-Lay decals traveling in the rain. Due to the rainy weather, the Semi’s windshield wiper was engaged. 

The short video showed the Semi’s mono wiper system, which uses two moving sub-arms that actively steer a single wiper, working in real-world conditions. Despite the Semi’s large windshield, one could see that the mono wiper system was cleaning a wide portion of the glass with each swipe. Some Tesla enthusiasts in the subreddit, however, have noted that such a wiper system may run into some problems during icy conditions. 

Mono wipers have never really become mainstream save for a few consumer vehicles, and definitely not for Class 8 trucks like the Tesla Semi. Mercedes-Benz infamously rolled out its “eccentric sweep” mono blade wipers in the 1980s, which cleared 86% of the windshield in a vehicle like the W124, more than any production car at the time, as per Hemmings. The novel mono wiper system was quietly retired in the 90s, however. Speculations suggest that this was partly due to the system being more complex and slower than a conventional dual wiper system, among other reasons.

Tesla appears to be fond of mono wipers for its larger vehicles. The Semi was launched with a single wiper setup, and as one could see in the recently-shared video, it actually seems like a great idea. The Cybertruck, however, was unveiled without a wiper at all, but sightings of production beta units in the wild suggest that the all-electric pickup truck might also be equipped with a single wiper system.

There is an issue, however. Unlike the Semi’s mono wiper, which is set up in the middle of the windshield, the Cybertruck’s large, single wiper in its production beta units is situated only on the driver’s side. This suggests that the all-electric pickup truck’s wiper system would likely not be as good as the Semi in rainy weather. Tesla seems to be aware of this problem though, with Elon Musk admitting on Twitter that the Cybertruck’s wiper system is something that “troubles” him the most about the vehicle.

Tesla Supercharger Diner food menu gets a sneak peek as construction closes out

What are you ordering at the Tesla Diner?

The Tesla Supercharger Diner in Los Angeles is nearing completion as construction appears to be winding down significantly. However, the more minor details, such as what the company will serve at its 50s-style diner for food, are starting to be revealed.

Tesla’s Supercharger Diner is set to open soon, seven years after CEO Elon Musk first drafted the idea in a post on X in 2018. Musk has largely come through on most of what he envisioned for the project: the diner, the massive movie screens, and the intended vibe are all present, thanks to the aerial and ground footage shared on social media.

We already know the Diner will be open 24/7, based on decals placed on the front door of the restaurant that were shared earlier this week. We assume that Tesla Optimus will come into play for these long and uninterrupted hours.

The Tesla Diner is basically finished—here’s what it looks like

As far as the food, Tesla does have an email also printed on the front door of the Diner, but we did not receive any response back (yet) about what cuisine it will be offering. We figured it would be nothing fancy and it would be typical diner staples: burgers, fries, wings, milkshakes, etc.

According to pictures taken by @Tesla_lighting_, which were shared by Not a Tesla App, the food will be just that: quick and affordable meals that diners do well. It’s nothing crazy, just typical staples you’d find at any diner, just with a Tesla twist:

As the food menu is finalized, we will be sure to share any details Tesla provides, including a full list of what will be served and its prices.

Additionally, the entire property appears to be nearing its final construction stages, and it seems it may even be nearing completion. The movie screens are already up and showing videos of things like SpaceX launches.

There are many cars already using the Superchargers at the restaurant, and employees inside the facility look to be putting the finishing touches on the interior.

It’s almost reminiscent of a Tesla version of a Buc-ee’s, a southern staple convenience store that offers much more than a traditional gas station. Of course, Tesla’s version is futuristic and more catered to the company’s image, but the idea is the same.

It’s a one-stop shop for anything you’d need to recharge as a Tesla owner. Los Angeles building permits have not yet revealed the date for the restaurant’s initial operation, but Tesla may have its eye on a target date that will likely be announced during next week’s Earnings Call.

Tesla’s longer Model Y did not scale back requests for this vehicle type from fans

Tesla fans are happy with the new Model Y, but they’re still vocal about the need for something else.

Tesla launched a slightly longer version of the Model Y all-electric crossover in China, and with it being extremely likely that the vehicle will make its way to other markets, including the United States, fans are still looking for something more.

The new Model Y L in China boasts a slightly larger wheelbase than its original version, giving slightly more interior room with a sixth seat, thanks to a third row.

Tesla exec hints at useful and potentially killer Model Y L feature

Tesla has said throughout the past year that it would focus on developing its affordable, compact models, which were set to begin production in the first half of the year. The company has not indicated whether it met that timeline or not, but many are hoping to see unveilings of those designs potentially during the Q3 earnings call.

However, the modifications to the Model Y, which have not yet been officially announced for any markets outside of China, still don’t seem to be what owners and fans are looking forward to. Instead, they are hoping for something larger.

A few months ago, I reported on the overall consensus within the Tesla community that the company needs a full-size SUV, minivan, or even a cargo van that would be ideal for camping or business use.

Tesla is missing one type of vehicle in its lineup and fans want it fast

That mentality still seems very present amongst fans and owners, who state that a full-size SUV with enough seating for a larger family, more capability in terms of cargo space for camping or business operation, and something to compete with gas cars like the Chevrolet Tahoe, Ford Expedition, or electric ones like the Volkswagen ID.BUZZ.

We asked the question on X, and Tesla fans were nearly unanimously in support of a larger SUV or minivan-type vehicle for the company’s lineup:

Here’s what some of the respondents said:

Tesla is certainly aware that many of its owners would like the company to develop something larger that competes with the large SUVs on the market.

However, it has not stated that anything like that is in the current plans for future vehicles, as it has made a concerted effort to develop Robotaxi alongside the affordable, compact models that it claims are in development.

It has already unveiled the Robovan, a people-mover that can seat up to 20 passengers in a lounge-like interior.

The Robovan will be completely driverless, so it’s unlikely we will see it before the release of a fully autonomous Full Self-Driving suite from Tesla.

Tesla has launched its first-ever Virtual Power Plant program in the United Kingdom. This feature enables users of solar panels and energy storage systems to sell their excess energy back to the grid.

Tesla is utilizing Octopus Energy, a British renewable energy company that operates in multiple markets, including the UK, France, Germany, Italy, Spain, Australia, Japan, New Zealand, and the United States, as the provider for the VPP launch in the region.

The company states that those who enroll in the program can earn up to £300 per month.

Tesla has operated several VPP programs worldwide, most notably in California, Texas, Connecticut, and the U.S. territory of Puerto Rico. This is not the first time Tesla has operated a VPP outside the United States, as there are programs in Australia, Japan, and New Zealand.

This is its first in the UK:

Tesla is not the only company that is working with Octopus Energy in the UK for the VPP, as it joins SolarEdge, GivEnergy, and Enphase as other companies that utilize the Octopus platform for their project operations.

It has been six years since Tesla launched its first VPP, as it started its first in Australia back in 2019. In 2024, Tesla paid out over $10 million to those participating in the program.

Tesla VPP program in California hits new capacity milestone

Participating in the VPP program that Tesla offers not only provides enrolled individuals with the opportunity to earn money, but it also contributes to grid stabilization by supporting local energy grids.
