Closer look at Tesla Model 3 Speed Limit Mode and Summon in mobile app
Tesla’s recent software update, v8.1(2018.24.1), introduced a number of new features for the Model 3, including Summon, cabin overheat protection, WiFi connectivity, and the ability to set speed limits on the vehicle.
Tesla enthusiast and Model 3 owner Ivan Karpenko recently shared a short walkthrough on how these features are accessed and adjusted through the Tesla mobile app. As could be seen in the video, setting the speed limits for the compact electric car on the mobile app is as simple as navigating to the Controls menu and scrolling down to Speed Limit Mode, which is located underneath Valet Mode. Speed Limit Mode is activated by tapping on a button and keying in a 4-digit PIN. Setting the maximum speed of the vehicle is just a matter of tapping or long-pressing the “+” and “-” symbols on the app.
Summon, on the other hand, is accessed by scrolling down the list of menus on the Tesla app and selecting the feature. In the mobile app’s current version, Summon is placed directly below Location. Tapping on Summon takes users into a menu displaying the Model 3, and if the feature had been activated in the vehicle, drivers would be able to command the car to move forward or in reverse.
Tesla’s new features for the Model 3 are focused on safety. Cabin overheat protection, which is enabled on Tesla’s electric cars by default, is a means to proactively prevent instances when children or animals get too hot when left inside the vehicle. Child fatalities resulting from in-car heat strokes is are severe problem in the United States. Last July 2017 alone, America saw 31 child fatalities — a record high at the time — resulting from heat strokes after children were left in a parked car.
Also notable in the Model 3’s recent updates is the Speed Limit Mode, which places limiters on the vehicles’ acceleration and maximum speed. Speed Limit Mode is described by Tesla as follows.
“Speed Limit Mode – This feature limits the acceleration of your vehicle and allows you to set a maximum speed limit between 50 mph and 90 mph. While your car is in Park, you can activate Speed Limit Mode by tapping Controls > Safety & Security on the touchscreen or by tapping CONTROLS on the mobile app. You must use the same 4-digit PIN to enable or disable Speed Limit Mode. A notification is sent to your mobile device is your vehicle approaches the set maximum speed. — In memory of Barrett Riley.”
Barrett Riley, 18, lost his life in a fiery accident after driving his Model S at speeds of 116 mph in a 30 mph zone, according to a Sun-Sentinel report. One of Barrett’s passengers, 18-year-old Edgar Monserratt Martinez, was also killed in the crash. In its investigation into the accident, the NTSB noted that the electric car was traveling at 116 mph three seconds before impact, slowing to 108 mph as the driver applied the brakes, and decreasing to 86 mph as it hit a wall.

After Barrett was cited for overspeeding last March, his father asked Tesla to adjust the vehicle’s speed through an over-the-air adjustment. Speed adjustments, after all, are already being implemented on loaner vehicles, which are limited to 85 mph. Based on the release notes of Tesla’s recent software update, it seems like Mr. Barrett’s requested feature can now help make Tesla’s fleet even safer.

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

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.

Elon Musk escalated his monthslong feud with Christopher Nolan’s The Odyssey this week, pledging that his own AI video tool will produce a competing version before the year is out. Responding to a fan-made, AI-generated clip of the ancient epic, Musk wrote on X, “Before this year ends, Grok Imagine will make a full-length movie of The Odyssey that is historically accurate and true to the art of Homer.”
In June, Musk quoted an xAI-shared trailer built entirely with Grok Imagine Video 1.5, a two-minute-plus reimagining of The Odyssey styled after a 1970s classical Hollywood epic, and predicted “full movies by the end of the year,” as Teslarati reported at the time. That trailer, built from 36 consistent shots by a single creator, was Musk’s proof of concept. This week’s pledge turns that prediction into a specific commitment, tied directly to Homer’s text rather than a generic demo.

— Elon Musk (@elonmusk) July 22, 2026
When a fan separately proposed that Musk fund a live-action alternative, to “give Mel Gibson $100 million to film an Odyssey adaptation with painstakingly historically accurate ships, armour, weapons, and casting, with all dialogue taken straight from the original poem and delivered in Homeric Greek,” Musk replied with two words: “I’m down.”
The Grok Imagine pledge lands as the tool’s underlying infrastructure has changed hands. Grok is no longer a standalone product, it folded into SpaceXAI after SpaceX’s acquisition of xAI closed in February, meaning the compute behind any Odyssey production traces back to the same Colossus supercomputers now bundled into SpaceX’s pitch to investors. Musk has separately said SpaceX’s own engineering data is being fed into the next major Grok training run, a two trillion parameter model he’s called the “2T run.”
Whether Grok Imagine can sustain a feature length narrative, rather than a series of impressive individual shots, remains the open question.
