Sometimes, in extremely cold weather, especially if it’s actively snowing and you’re Supercharging, the charging cable can freeze and get stuck to the vehicle. That can be a bit of a hassle at a minimum—or cost you dearly if the cable is stuck at a Supercharger and you’re accruing idle fees.
If you use the “Rear Defrost” button in the Climate Controls, your Tesla's charge port will also automatically defrost. However, it’s not obvious to most users that the rear defrost button also turns on the charge port heater. While we’re talking about what’s not obvious, the rear defrost button also turns on your heated mirrors.
There are other ways to turn on your change port heater, but none of them are dedicated to the function. Preconditioning your vehicle or hitting the “Defrost Car” button in the app, will also turn on the charge port heater.
Sadly, the last two options also heat your cabin, which isn’t exactly needed every time. That can be annoying - because it’ll heat your cabin very fast, given the strength and effectiveness of Tesla’s heat pumps.
Your vehicle will also defrost the port if you’re en route to a Supercharger, so it’ll have the port warmed up and ready to receive the connector - ensuring the flap isn’t stuck. However, it’s not helpful if the cable gets stuck while your’re charging.
Charge Port Defrost
Tesla has finally added a solution to this problem. You can now manually turn on the charge port heater by going to Controls > Service > Charge Port Heater. However, the feature is not available on all vehicles. It’s only appearing in the release notes for a very small segment of vehicles. We’ve confirmed that it is showing up on a 2024 Model X and some 2023 Model Ys on Tesla software update 2024.44.3.1.
Which Vehicles Have Charge Port Heaters?
Every Tesla has been equipped with a charge port heater since late 2020, and some older vehicles may or may not have the necessary equipment. The cut-off date for charge port heaters appears to be approximately September 2020, but some vehicles produced earlier may have it.
However, the release notes only show the charge port heater option for a small selection of vehicles. If your vehicle was manufactured after 2020, you can check if you have the new option by going to Controls > Service or looking under the “Minor Updates” section of your release notes. The release notes will state the following item if the new option is available:
“Heat your charge port in case your charge cable is frozen stuck. Go to Controls > Service > Charge Port Heater.”
This is a great addition for people who live in colder climates - and super useful. If you happen to have parked with your charge port facing blowing snow, you’ll know the struggle of the port and cable freezing together - and some people even buy third-party shields to cover the connector port while charging to keep this from happening. The next step for Tesla will be to automatically heat the charge port when you’re nearing your scheduled departure state of charge to allow for easy unplugging.

During the unveiling of the Cybercab at We, Robot last year, we saw the Cybercab use a strange laser-like lighting system to project an interesting light pattern. It was a rather peculiar projection, and many observers passed over it without wondering too much - perhaps it was just a trick of the show?
But we went back and thought - what is it really? What kind of lighting technology could Tesla be using to accomplish this visual effect, and does it have a purpose? That led us down the rabbit hole of Structured Light, and we think that Tesla could be using this technique for a few different things.
Cybercab’s Autonomy
Unlike other autonomous vehicles, which are often retrofitted with complex and expensive sensor arrays, the Cybercab is purpose-built to be a mass-market autonomous taxi. Because of that, Tesla is using several new techniques to drive down the cost and simplify the vehicle, from the paint-impregnated panels to the easy-to-clean interior.
However, the drive to keep costs down hasn’t stopped Tesla from looking for ways to present a premium and safe product, which has been one of the Engineering and Design team’s goals for a long time.
Structured Light is a technique involving the projection of light using a distinct pattern. In particular, it’s a machine vision technique for capturing 3D information. Unlike normal, ‘passive’ cameras that interpret ambient light, structured light actively projects a known pattern, such as lines, grids, or dots, onto the environment.
A camera will then observe how the pattern deforms as it hits objects. By analyzing these distortions, the system can precisely calculate the 3D shape and depth of the scene in front of it. Structured light can generate dense, high-resolution 3D data, which is particularly useful at short ranges.
But is this useful for an autonomous vehicle? Potentially. It offers a close-range means of mapping the environment directly in front of the vehicle, and could theoretically complement the existing camera suite for precise maneuvering in tight spaces. It could also be used for detecting low-lying objects, although this task could be handled by the bumper camera that is arriving on newer Tesla vehicles as well.
Structured Light vs LiDAR
Not a Tesla App
The mention of an active 3D sensor brings to mind LiDAR (Light Detecting and Ranging) - which Elon Musk has repeatedly called a crutch for self-driving. But LiDAR is different than Structured Light - it emits a pulse of laser light and measures the time of flight to generate a 3D point cloud of the environment.
While both involve projecting light, structured light systems require specialized hardware distinct from Tesla's current Matrix LED headlights. Matrix headlights are designed to intelligently block parts of the main beam to prevent dazzling other drivers, using an array of controllable LEDs.
Structured light, conversely, requires a dedicated projector to cast a specific, known pattern (dots, lines, or a grid) precisely so a camera can analyze its deformation for 3D mapping. Implementing structured light would likely involve adding a new, dedicated projector component - perhaps another Cybercab exclusive feature.
Tesla already uses computer vision to navigate the environment, and adding Structured Light could potentially aid this process for Robotaxi challenges and edge cases, while not deviating from Tesla’s policy to use the same senses that a human uses to drive.
Structured light could be Tesla’s potential intelligent solution to an active 3D sensing system without adopting a more traditional approach like LiDAR.
Other Uses
Beyond the possibility of 3D sensing, could this light projection serve other purposes? Tesla is known for integrating novel new features into its vehicles - sometimes practical, sometimes just for fun. There are a few possibilities here.
Visual Communication - The lights could be used to project information onto a road surface - perhaps showing the vehicle’s intended path, or displaying warnings to pedestrians. It could even project a virtual crosswalk to signal that it is safe for pedestrians to pass.
Passenger Guidance - For a taxi without a driver, guiding passengers on how to approach and use the Cybercab could be useful. A projected welcome mat could show passengers exactly how to get into the Cybercab, reveal which passengers are being picked up, or provide other important information.
Improved Light Shows - We all know Tesla loves the little things in life. The projection could be used for more whimsical Light Shows in the future. We’re sure they’ll have more than just that in mind, though.
Wrapping Up
While we haven’t had any official confirmation that Tesla is using Structured Light, the possibility of the Cybercab using a novel new technology is relatively fascinating. It suggests that Tesla is looking into using its pre-existing tools and features in even more ways - something that they’ve always focused on. Whether this projection is for sensing or communicating, or even just for fun as a light show, we won’t know until Cybercab actually hits production.
One idea that consistently comes up when discussing the future potential of FSD is the ability to order a Tesla and have it arrive at your home—completely autonomously.
Picture this: a car rolls off the assembly line at Giga Texas, drives itself to the outbound delivery lot, and merges onto the highway—completely driverless. Its destination? A customer in upstate New York. Along the way, the vehicle independently plans its charging stops, navigates traffic, and drives nonstop, no breaks needed, until it pulls into the buyer’s driveway.
Of course, there’s a lot to consider and break down - but Elon Musk doubled down and said that he intends to have Tesla vehicles deliver themselves autonomously by the end of 2025. We’re sure there are some stipulations to that, but it’s an exciting idea that could save Tesla thousands per vehicle sold.
The core idea is that FSD Unsupervised is nearing completeness, with the upcoming launch of Tesla’s first Robotaxi network slated for June. Once Tesla can demonstrate that Unsupervised driving is safe, it will expand beyond simply transporting passengers from Point A to Point B.
That will include moving vehicles from factory to consumer, which will vastly streamline Tesla’s delivery process - and really make a statement about how far Tesla is ahead of the competition.
Reduced Delivery Costs
One of the biggest keys for Tesla throughout its history has been its ability to drive down costs. Delivery costs add to the price of a vehicle, and it’s not just the price of transporting the vehicle, but the cost of the whole delivery experience — delivery center and personnel included.
Instead, if a future Tesla drives itself directly to the consumer, Tesla can further reduce the price of its vehicles or improve its profits.
Improved Customer Experience
Money aside, the real game-changer is that no other vehicle delivery experience will come close to Tesla’s. What other brand will be able to deliver a car that drives itself to your home—straight from the factory?
Having a vehicle deliver itself can also provide other benefits, such as faster delivery times for customers. The customer also won’t need to drive to a delivery center to pick up their vehicle. The vehicle would go directly from the factory to the customer without any steps in between.
There’s something undeniably futuristic about getting a notification on your phone, glancing outside, and seeing your brand-new Tesla autonomously pulling into your driveway.
Limitations
Of course, with any new process or feature - there will be limitations and hurdles for Tesla to address, and these will take time and effort.
Let’s discuss some of the hurdles Tesla will need to solve.
Charging Infrastructure
Besides achieving true autonomy, another big challenge will be charging infrastructure. No Tesla can currently plug itself in at a Supercharger - they’ll need access to the upcoming V4 Superchargers with Wireless Charging to take on a road trip autonomously.
That will be a challenging rollout in the initial few years, especially as Tesla hasn’t been actively replacing older V2 Supercharger sites just yet - and is instead focusing on deploying new ones. We imagine that the rollout of wireless charging will likely also be limited, and it is likely that only Tesla’s more premium vehicles and Robotaxis will receive wireless charging compatibility.
Autonomy Policies / Geographic Limitations
Tesla has been consistently hamstrung by red tape, and unsupervised deliveries will also be a massive hurdle to clear with many states and provinces, as well as at the federal level. That will be an implicit challenge for Tesla in the infancy of the Robotaxi network as well, but once approvals spread wider, we can see these restrictions being lifted and relaxed.
Mileage and Damage
One item that could be a sticking point for customers is mileage and damage. If your brand-new vehicle was damaged on its trip over, what would you do? You’d have to take it from your driveway right to the Service Center, effectively invalidating the entire experience.
Of course, many people will also want to see a low odometer on arrival of a brand new, fresh-from-factory vehicle - and that’s understandable. Having a car arrive with several hundred or even a thousand miles of wear and tear on the tires and paint could be a big negative as well.
What Is Likely to Happen
We think that Tesla will continue to ship vehicles longer distances - but perhaps once they’re offloaded at your local Service Center, an employee taps a button, and begins the self-delivery process. That eliminates many of the above problems we’ve outlined, including charging and additional mileage, while keeping many of the advantages intact.
For any customers who order a Tesla in Austin later this year, it’s possible Tesla could have the vehicle delivered directly to you.
