Kman has been producing videos about Tesla since 2013, when he took delivery of a 60 kWh Model S. His latest opus is a four-part collection of handy tips and tricks for Tesla drivers.
Kman includes a raft of recommendations for increasing range. Most of these will be familiar to any energy-conscious driver, but the analytically-minded Kman has tested the techniques, and offers a pretty precise assessment of exactly how much juice each suggestion will save.
Obviously, it’s good to keep the total vehicle weight down – consider taking that bowling ball out of the trunk if you don’t use it much. However, Kman has found that the additional weight of passengers and cargo affects range far less than other things, such as tire pressure.
Like most cars, Model S has a sticker on the door jamb listing the recommended tire pressure. However, Kman has found that using the recommended pressure increases his energy consumption (and feels “squishy”), so he uses 50 psi on the rear and 48 on the front, instead of Tesla’s recommended 45.
We all know that Tesla’s Range Mode increases range. Kman explains exactly how it works, and what the trade-offs are (mostly stuff you can do without).
Slow down! Everyone knows that vehicles (electric or fossil) are more efficient at slower speeds. Kman has calculated that the optimum speed for Model S is 24 mph. If you could somehow manage to drive around at a constant 24 mph, you should get as much as 550 miles of range.
Auto racing fans know that drafting – the practice of following closely behind another vehicle to cut down wind resistance – saves energy. Tesla’s adaptive cruise control makes this easy – just set the desired distance from the vehicle ahead of you. Kman claims he has seen a 40% increase in range drafting a semi truck.

Climate control is another well-known energy hog, but in an EV, heating uses much more power than cooling (gas cars use waste heat from the engine for cabin heating). If you can get by with the Tesla’s seat heaters, you’ll save some range, as using them is much more efficient than heating the whole cabin.

There seems to be a bit of controversy when it comes to ride height. Theoretically the lowest suspension setting saves range on the highway, but some Tesla drivers claim that it increases tire wear, and that medium ride height is best. Your mileage may vary.
Model X is rated to tow a trailer of up to 5,000 pounds, but it will cost you in terms of range. Figure on at least a 50% reduction in range when towing. Kman points out that the aerodynamics of a trailer are much more important than weight. Officially, Model S can’t tow at all, but Kman claims it can tow up to 2,000 pounds (sounds like something that could void the warranty if anything goes wrong – be careful).
Next, Kman debunks the common belief that charging to 100% reduces battery life. In fact, the big no-no is charging to 100% and then leaving the car sitting around in high temperatures. But topping up is fine if you’re going to be driving right away, and it’s the easiest and most obvious way to maximize your range.
No matter how careful you are, you’re going to run out of energy eventually, so it’s best to be prepared for various charging scenarios, especially when taking road trips. It’s handy to have a collection of charging adapters in the car, including a CHAdeMO adapter and a couple of adapters for different types of 240-volt receptacles (even if you have to spend some time searching for them, as Kman does). And keep a heavy-duty extension cord in the car in case you ever need to plug into a regular outlet somewhere on the road.
Another handy accessory is a ChargePoint account, which gives access to thousands of public chargers. Theoretically you can initiate charging just with the smartphone app, but that won’t work if there’s a dodgy internet connection, so order the free card and keep it in your vehicle (there are various other regional charging networks, some of which require their own cards).

The real reason Elon Musk wants every car connected to space
Elon Musk says all cars will eventually need Starlink to handle massive AI bandwidth demand.
Elon Musk is making the case that satellite internet, not fiber or cellular towers, will end up wired into every car on the road. In a string of posts on X, the SpaceX CEO wrote that all cars will have Starlink in the future and called satellite connectivity the only way to get super high bandwidth to billions of vehicles.
The posts started with Musk endorsing a Cloudflare forecast that traffic generated by autonomous AI agents will soon dwarf traffic generated by humans browsing the internet, a shift he described as not a close call at all. From there he narrowed the argument to infrastructure, writing that the only system that can support the insanely fast bandwidth growth needed by AI is Starlink, before extending the logic to cars specifically.
AI agentic Internet traffic will obviously VASTLY exceed human usage. Not a close call at all.
Cloudflare’s forecast is accurate. https://t.co/VztgrinN5k pic.twitter.com/Wo4FiRKjPU
— Elon Musk (@elonmusk) August 9, 2026
The timing lines up with Tesla’s own hardware decisions. On July 20, Tesla confirmed the Cybercab would ship with a Starlink V5 terminal built into its roof, the first time the company had put satellite hardware in a production vehicle. A day later, Tesla’s head of AI, Ashok Elluswamy, explained the connection wasn’t there for safety and that Cybercab’s driving stack runs entirely on onboard cameras and compute, while the satellite link exists for navigation, customer service, and fleet management instead. Musk followed with his own post about the feature, saying riders would be able to watch 4K streaming video during rides.
By July 22, Musk had already said Starlink would extend beyond Cybercab to Tesla’s full lineup. Sunday’s posts push that same logic outward again, this time framed as a requirement across the industry rather than a feature specific to Tesla, and tied directly to the bandwidth AI systems are expected to consume.
SpaceX’s newest Starmind will make earth data centers obsolete
-
The AI argument has been building on SpaceX’s side for months. The company has an FCC filing pending for a third generation Starlink constellation, and it has separately proposed Starmind, a constellation of up to a million satellites designed to run AI computation directly in orbit rather than just relay data. Musk has said he expects space to become the cheapest place to deploy AI compute within two to three years. Starlink and Starmind serve different jobs inside that vision, one moving data and the other processing it, but Sunday’s posts treat vehicles as one more category of hardware that will eventually need both.
None of this changes anything for Tesla owners today. Cars already on the road keep running on LTE and Wi-Fi, and Tesla hasn’t outlined a retrofit path for existing vehicles. The July 22 commitment applies to future production, not the fleet already delivered. What Musk added on Sunday is the reasoning: satellite connectivity isn’t a Cybercab novelty, it’s a bet that ground based networks won’t keep up with how much data cars, robots, and AI systems are about to generate.

The Boring Company’s newest tunnel vehicle runs on Tesla parts and no one is driving it
The Boring Company’s new tunnel vehicle runs on Tesla Model 3 batteries and drive units.
The Boring Company just introduced a new piece of hardware, and it runs on parts pulled straight from a Tesla showroom. Liner Truck 3, unveiled in a post from the tunneling company’s official X account, is an all electric vehicle built around Tesla Model 3 battery packs and drive units, purpose built to move concrete tunnel segments to the boring machine face without a single person underground.
Introducing Liner Truck 3 — our latest fully electric tunnel vehicle.
– Tesla Model 3 battery and drive units
– Transports 22,000+ lb of concrete segments to the boring machine
– 28 miles of range
– 12 mph max operating speed
– Remotely piloted from Global OCC in Texas, with… pic.twitter.com/XB7FgSXnpy— The Boring Company (@boringcompany) August 7, 2026
The job itself is unglamorous but critical. Each precast segment run weighs more than 22,000 pounds, roughly the load of a full cement mixer, and Liner Truck 3 hauls that weight repeatedly between the surface staging area and wherever the Prufrock machine happens to be cutting.
The Boring Company said Liner Truck 3 is piloted remotely out of its Global Operations Control Center in Texas, extending the Zero-People-In-Tunnel approach the company has spent years building toward. An earlier version of a ZPIT liner truck was already tested at the company’s Bastrop, Texas research tunnels, and a factory tour released last month showed an employee flying a fully loaded liner truck with a PlayStation controller. Liner Truck 3 looks like the production version of that same idea, cleaned up and pushed into daily use.
The timing lines up with a company digging in more places than it ever has before. The Boring Company now has multiple Prufrock machines active or arriving in Nashville, where Music City Loop construction has been accelerating since February, and its Vegas Loop network keeps adding tunnel mileage on a near monthly basis. Every one of those projects depends on getting concrete segments to the cutting face fast enough to keep the boring machine from idling, which is exactly the bottleneck Liner Truck 3 is designed to remove.

It also reinforces something Tesla owners have watched happen gradually across Musk’s companies: passenger car hardware finding a second life in heavy equipment. Model 3 drive units already move people through the Vegas Loop, and now the same components are hauling concrete underground in Nashville and wherever The Boring Company digs next. Whether that kind of component reuse extends further into TBC’s equipment lineup, or into other Musk owned industrial hardware, is the next thing worth watching.

Tesla unlocks in-car web conferencing to extend Google Meet, Teams and beyond
Tesla’s Summer Update lets owners join Google Meet, Teams, and Discord calls via cabin camera.
Tesla’s 2026 Summer Update, which just began rolling out to customer vehicles, now links the built-in web browser with the in-cabin camera feed and microphone input, thereby letting owners join video calls on nearly any browser-based service instead of just Zoom.
The change appears in Tesla’s own release notes for software version 2026.26 under “Web Browser,” which states that the vehicle can now use its interior camera and cabin microphone when a website requests access, with permission granted the same way a desktop browser handles it. As NotATeslaApp notes, this feature opens the door to Google Meet, Microsoft Teams, Discord, and other webcam-enabled sites to activate the in-car cabin-facing camera. The feed automatically crops and zooms to center the driver in frame.
Tesla has offered in-car video calling before, but only through a dedicated Zoom app that launched at the end of 2022, a stripped-down browser preloaded with Zoom’s own web client and gated behind Premium Connectivity. Opening the full browser to any camera-requesting site removes that walled garden. Elon Musk first called video conferencing “definitely a future feature” back in 2020, when the pandemic pushed remote meetings into daily life, so this update effectively finishes something Tesla has been promising for six years.
Tesla Summer Update begins rolling out: a look at the new features
The feature keeps the same restrictions that applied to Zoom on Tesla vehicles. It only works while the car is parked; shifting into Drive disables the camera feed, according to the release notes. It is also limited to vehicles running Tesla’s AMD Ryzen infotainment hardware, meaning older Intel-based Model S and Model X units, along with early Model 3 and Model Y builds, don’t get it.
Turning the browser into a general entry point for the in-cabin camera, rather than routing everything through one local app, widens the number of third-party sites that can ask for access, even though Tesla’s permission prompt.
With the Summer update only days into its rollout, be sure to stay with us on TikTok and X to see the latest video demonstrations.
