Glamping, a word that combines the terms, glamour and camping, refers to going to campgrounds but having the amenities normally present in a hotel.
Tesla has an interesting Cybertruck trailer concept. It's a large trailer about the size of a tiny house. It’s a nice looking trailer and it reflects the angularity and aerodynamic shape of the Cybertruck. In Cybertruck patents, Tesla shows the Cybertruck pulling a weight of 20,000 pounds, however the official Cybertruck specs say it can tow more than 14,000 pounds. I interpret that as a max weight of between 14,000 pounds and 15,000 pounds.
Now, remembering what we learned in high school physics, you’ll recall that how much weight a truck can tow has three components. The truck has to overcome rolling resistance, air resistance, and gravity. Now rolling resistance increases gradually depending on both the weight of the trailer and the speed you’re trying to tow it. It’s a linear increase. While there’s more rolling resistance at highway speeds than there is at parking lot speeds, it’s not all that much more.
Then there’s air resistance. That’s not related to the weight of the trailer at all. Air resistance is related only to the cross sectional area of the trailer, the aerodynamic shape of the trailer, and the speed of the tow. Air resistance increases as the square of the speed, so that’s a much more significant factor at highway speeds than at low speeds, but it has absolutely nothing to do with the weight of the trailer.
A few months ago, Ford came out with a publicity stunt involving a prototype electric Ford F-150 Lightning towing a million pounds of railroad cars when they were empty. Then they loaded one and a quarter million pounds of pickup trucks into the railroad cars, and the electric Ford towed all that, too (you can watch the full video below).
It was supposed to demonstrate something. All it demonstrated is that Ford likes to lie to people who don’t remember the physics they learned in high school.
The tow was done at slow speeds on steel rails with steel-wheeled railroad cars. Of all the land vehicles currently in use in the US, trains have the least rolling resistance. Maglev trains have less rolling resistance, but they’re not in use in the US. And anyway, maglev trains don’t roll. They float on a magnetic field. So all the electric Ford had to do was overcome a certain small rolling resistance. Admittedly, you or I would have been unable to start those train cars rolling by pulling or pushing by hand, but probably any pickup truck could have done it. It didn’t have to be a Ford.
The reason there’s a weight limitation for towing a trailer is that roads aren’t level. On hills, there are two considerations. The truck needs to be able to tow the trailer up any hill it might come across, and it has to be able to control the trailer when going down any hill it might come across. So if Tesla says the Cybertruck is rated for 14,000 pounds, then it really shouldn’t try towing 20,000 pounds even if that seems possible on level ground or mild hills. But there is a way around this limitation in the era of electric vehicles.
What I’m going to tell you does not come from Tesla, or any knowledgeable source. It comes strictly from my imagination so take it with a grain of salt.
The way the Cybertruck can safely tow a load that’s higher than its rated maximum towing weight is if the trailer has its own batteries and its own electric motor(s). There would, of course, have to be coordination. The trailer would have to respond to the truck driver’s control input, but that’s not difficult to arrange. If the trailer had batteries and motor(s), the range between recharges would not be degraded by towing. If the trailer could be recharged separately from the Cybertruck by a second Supercharger stall, then the length of time to recharge wouldn’t be prolonged.
Now let’s talk about what the trailer could include. I looked up the weight of a standard 30-foot travel trailer. The weight averages around 5,800 pounds. So that leaves plenty of room for amenities. The trailer could expand, for example. It could expand upward when parked, or sideways. Lots of travel trailers do that. So instead of being 30 feet by 8 feet, it could be twice that. Perhaps it could expand sideways on both sides, That would make it 30 feet by 24 feet.
Add to that interior room, an extra roof to cover an outdoor patio, another 8 feet by 30 feet. Cover all that roof with solar panels, and you’d have lots of electricity while you were at the campground. Excess solar electricity created in the daytime would be stored in the trailer’s batteries at night.
Then there are other amenities. In addition to the normal water tanks for drinking, bathing, and other cleansing purposes, there could be a hot tub for two. That would hold 150 gallons of water, 600 pounds. Tesla is good at making heat pumps. Heat pumps can be used to heat or cool the trailer depending on the outside air temperature. If the trailer is parked near a stream or a lake, the heat pump might be able to exchange heat or cooling with the body of water if that would be more energy-efficient than exchanging heat or cooling with the outside air.
While traveling, there should be enough outside video cameras so that the driver would not have blind spots next to or behind the trailer. These should sync with the Cybertruck’s display screen.
The Ford F-150 Lightning has a helpful feature for hooking up the truck to a trailer. The driver first cranks up the trailer’s hitch to the proper height. Then he drives the truck to the front of the trailer so he can see the trailer hitch in the rear camera display. At that point, the truck itself backs up until the truck’s trailer hitch is properly aligned with the trailer’s hitch receptacle. Tesla should do that for the Cybertruck in a software update.
Finally, there should be Internet access via Starlink.

In the race to deploy autonomous vehicles, there have been two schools of thought. One is led by sensor fusion, which means the more sensors and the more types, the better. The other is Tesla’s school of thought — vision.
So far, even Google’s CEO, Sundar Pichai, has described Tesla as the leader in the autonomy sector.

A new analysis from Bloomberg (paywall) offers a similar perspective, focusing on the numbers and real-world safety metrics. Tesla’s strategy isn’t just viable - it is far outpacing its competitors.
A Tale of Crash Rates
The most striking numbers from Bloomberg’s analysis are safety-related. According to their comparison, FSD reports approximately 0.15 crashes per million miles driven. In contrast, Waymo reported approximately 1.16 crashes per million miles.
That means that a Tesla using FSD is seven times less likely to be involved in a crash than a Waymo vehicle, even with its bevy of sensors. This is in line with Tesla’s latest vehicle safety report, which notes that a Tesla using FSD is 10 times less likely to be involved in an accident than a driver in any other vehicle.

When it comes down to it, sensor fusion, while it can be fantastic, it simply provides too much data to process and analyze. While LiDAR, radar and cameras all have their unique advantages, cameras end up being the most versatile. Our roads and world were created around vision and audio, so a LiDAR-only vehicle can’t navigate our roadways since it would be unable to see signs or any other object that lacks depth. For LiDAR to be useful, it needs to be coupled with vision.
Vision works well because it applies to all situations, and it’s a system that continues to improve thanks to advancements in image processing and AI. While measurements with vision still lag behind LiDAR, they’ve reached a point where they’d “good enough,” and the millimeter-level accuracy of LiDAR isn’t needed.
When radar and vision disagree, which one do you believe? Vision has much more precision, so better to double down on vision than do sensor fusion.
Besides the difficulty of using sensor fusion, Bloomberg also points out that Tesla’s advantage is in the fundamental cost of the hardware. The Model Y costs just 1/7th of the total cost of a Waymo vehicle.
This enormous cost difference is a direct result of how Tesla and Waymo are approaching autonomy. Waymo’s vehicles are high-end, third-party electric cars, like the now-discontinued Jaguar I-Pace, which are then retrofitted with an expensive, custom-built suite of sensors. This sensor suite includes multiple LIDAR units, radars, and cameras.

Tesla, meanwhile, includes all the hardware for autonomy as standard equipment on each of their vehicles, with a relatively inexpensive suite of cameras and its own in-house designed FSD computer. Using affordable hardware means it’s easy to produce and field more vehicles, resulting in more data.
On top of that, building more vehicles at a lower price creates a larger and larger economic difference as time goes on, as Tesla’s Robotaxis become profitable far quicker than Waymo’s.
3 Billion Miles… and Counting
The biggest advantage that Tesla has over any other entrant into the autonomy ring is simply just data. Tesla’s fleet has gathered over 3 billion miles of driving data globally, whereas Waymo’s fleet is just a minuscule 22 million miles.
Putting that into perspective, for every mile driven by a Waymo vehicle, a Tesla has driven over 135. Tesla’s advantage is also the fact that its data is global. It includes vehicles operating in a range of environments, from deserts to the Arctic, from cities to extremely rural areas, and is capable of achieving generalized autonomy.
Waymo’s data is extremely focused on urban and suburban areas and is effectively unusable for generalized vehicle autonomy. A larger, more capable fleet is the key to providing an effective robotaxi service, after all.
Scaling Manufacturing
Finally, Waymo doesn't produce vehicles. Tesla produces Robotaxis from scratch - every vehicle off the line has the ability to run Unsupervised FSD, and eventually join the Robotaxi fleet. Waymo needs to partner with other companies that have a good platform, and they must adapt their technology to that platform.
Waymo’s fleet is expected to be 2,500 vehicles by the end of 2025, while Bloomberg expects Tesla’s functional fleet to hit 35,000 by the same time. That’s not even counting the millions of AI4-powered vehicles that could also join the fleet by late 2026.
Overall, Tesla is a clear winner in the Robotaxi race - and it isn’t just because of one element. They’re winning through data, cost, and scalability, and the gap will only continue to grow.
For several months, we’ve been hearing rumors that Tesla is developing a new variant of the Model Y, one equipped with six seats rather than the five or seven we’re accustomed to seeing. Many people have been holding out for exactly such a variant, one that’s big enough to hold larger families without being as tight on legroom as the seven-seat variant.
Now, thanks to confirmation from Tesla hacker @greentheonly, we now have the strongest evidence yet that Tesla is making a six-seat variant, likely in a unique configuration, as he found in the latest batch of vehicle firmware.
Green found references to the six-seater Model Y in the 2025.20 update, validating the rumors we’ve heard. Given that the references are showing up in production software, Tesla may now be actively testing the vehicle. The next place to watch will be code in the Tesla app, which should hopefully provide us with some previews of the seat layout.
Captain’s Chairs
So, what would a six-seat Model Y actually look like? Well, the configuration all but guarantees a 2x2x2 seat layout. That configuration would replace the traditional second-row bench seat with two more spacious captain’s chairs, which will have an aisle between them. That’s a big bump in comfort for second-row passengers, who would have seats more similar to the ones up front. Tesla didn’t include armrests on the six-seat Model X, so it’s likely the Model Y won’t have them either.
For the Model X, the seven-seat configuration is a $3,500 bump in price, while the six-seater costs an additional $6,500, so expect the Model Y to have a similar price structure.
We can also expect Tesla to add some convenience features into this package, similar to the power-reclining seats introduced in the new Model Y, which can automatically fold and unfold with the tap of a button. In a six-seat Model Y, the middle seats would likely be able to automatically move forward and backward, while the rear two seats would be the folding ones.
Front seats learned some manners

However, most importantly, this 2x2x2 layout creates a center aisle. This provides easier access to the third row, eliminating the need to fold down the center bench seat to get in and out of the vehicle. That’s a big improvement for families who use the third-row regularly.
Confirming Rumors
This firmware update actually confirms rumors we heard back in December 2024. China’s Latepost and Reuters had already indicated that a six-seat variant was in the works back then, but many agreed that the variant would be an exclusive option for the Chinese market. That particular market prefers having spacious second-row seating, and the six-seater just makes sense there, given the offerings of other manufacturers.
Now, with Green’s assessment that a global release is more likely helps to confirm those reports, while also providing some hope for customers in North America and Europe who have been holding out.
Utility vs Comfort
The plot thickens when we look at the fact that Tesla just teased another recent development - the Model Y seven-seat variant. Some customers in North America and Europe received emails teasing the return of the seven-seat Model Y.
But why would Tesla release both? Likely for similar reasons that they have a six-seat and seven-seat Model X. The answer is that some will value the utility of the seven-seat option, while others will value the comfort and premium feeling of the six-seat option.
By offering both, Tesla gives its customers a bit more customization and preference, especially those who often have to look outside the brand for larger family vehicles.
Longer Wheelbase
While the firmware finding confirms the seating configuration, there have also been some rumors from Chinese bloggers about the possibility of a longer wheelbase, known as version E80. If this proves to be true, the six-seater would be more than just a new interior layout; it would be a fundamentally larger vehicle. Recent rumors suggest the vehicle may have a wheelbase that’s 5.9” longer than the regular Model Y, which would significantly increase the legroom available in the third row. While the third row may have ample legroom in this longer wheelbase, it would likely still be limited for smaller individuals due to the available headroom.
The Tesla Model X is Tesla’s only current offering for larger families, but it costs significantly more than the Model Y. A six or seven-seater Model Y could help open up a whole new category for Tesla.
Price
We expect that Tesla will likely price the seven-seat variant for an additional $2,000 USD ($3,000 CAD), and the six-seat variant for an additional $4,000 USD ($5,000 CAD) in the North American market, based on the pricing of the old seven-seat variant and the Model X’s six-seat premium configuration.
Below is a video of the seven-seater Model Y:
What Next?
The addition of the six-seat Model Y to Tesla’s public software that’s being delivered to vehicles today practically confirms that Tesla is looking to release a six-seat version of the Model Y. While the longer wheelbase remains speculative, we could expect Tesla to unveil a six-seat variant in the coming months. Alongside the seven-seat variant, customers shopping for a larger vehicle will have some additional choices soon.
