Level 5 autonomy is the Holy Grail of modern driving technology. It is essentially the point at which autonomous vehicle will be wholly self-sufficient on the roads â€" to the point that they may not even have steering wheels or pedals for drivers. And while this level of self-driving technology still seems like science fiction to many, we may also be closer to it than we think.
As was noted in our recap of Tesla discussions with the DMV, Elon Musk has even suggested that FSD will be at level 5 by the end of this year. Tesla's own engineers are dubious of this prediction, but it still speaks to the rapid progress some industry leaders are aiming for.
This begs the most interesting question of all, which is not when we'll see level 5 autonomous vehicles, but rather what a future with such vehicles will be like. Even if we reach this level at some time in the next five years it will represent a massive leap forward into an era that would once have seemed virtually impossible. So what exactly will it look like?
Public Transport Will Change
For a while now people have predicted that fully autonomous vehicles will ultimately replace taxis, Uber, and Lyft, such that whole fleets of robotic cars will be available to pick us up and drop us off as needed. Last year, we got an interesting look at a concept car that could serve this purpose when an Observer article on a GM unveiling showed us a self-driving vehicle that almost resembled a tiny bus or tram car. And for that matter, there is also the distinct possibility (if not inevitability) that autonomous tech will be used in city buses as well.
Add all of these possibilities up, and you quickly come to recognize a wholly evolved form of public transportation. This is one aspect of the transition to level 5 that is troubling to some, because unfortunately it will almost certainly mean a lot of job (and "gig") loss. Nevertheless, in time we'll almost certainly be summoning autonomous vehicles to move around town.
Vehicle Interiors Will Be Unrecognizable
It seems likely enough that the very first level 5 cars will resemble what we're used to. They may not have steering wheels or pedals, but for the most part they'll look like nice, modern cars â€" because they will probably be ordinary modern cars adapted to level 5. Over time though, the fact that humans aren't needed to drive will likely result in completely changed interiors. We could see video screens for entertainment, chairs that swivel around to face the rear, lounge-style seating in ordinary sedans, and all kinds of other changes.
We'll Have Cyber Support for Cars
This is an interesting point to consider because it actually represents intersecting trends: that of progression toward autonomous vehicles, and that of general cybersecurity needs. Regarding the latter, our world already revolves so much around digital practices and automated systems that cybersecurity has become one of the busiest fields of work. Young people are studying the subject on their way up through school with the hopes of finding strong jobs in the field. And many working adults are pursuing cybersecurity via online courses, so as to qualify for what Maryville University's online bachelors in cybersecurity brochure describes as a "booming industry," with significant growth and six-figure salary positions.
In short, the digitization of our world is already giving rise to an army of cybersecurity experts, and it's a virtual certainty that they'll be needed in support of vast new networks of level 5 autonomous vehicles. We'll likely be replacing much of what we think of now as car service with software updates, security patches, and general cyber support. Maintaining a vehicle may well be more like maintaining a computer than a present-day gas car.
Gas & Service Stations Will Vanish
As mentioned just above, a lot of the regular maintenance for level 5 vehicles will concern digital adjustments. We'll download system updates and check in with cyber experts now and then, perhaps through entirely digital means. We won't, however, conduct ordinary maintenance as we think of it today, from loading up on gas to pulling into a station for an oil change or engine tune-up. Accordingly, gas and traditional service stations will begin to vanish, and perhaps one day completely disappear.
A New World of Regulations & Rules Will Emerge
One of the more pessimistic assessments of self-driving progress we've seen of late came via an article by Swinburne University of Technology professor, who argued that for several reasons we're still pretty far off. We could quibble with the tech argument to no end, but the interesting point made by said professor was that regulations are not yet in place to manage a society full of level 5 autonomous vehicles. This is indeed a large problem that will take time to solve, and which may delay the transition to self-driving vehicles even if and when the tech is all in place.Eventually though, it will be worked out, and a whole new world of road regulations and rules will emerge. The hope is that vehicles will seamlessly follow these rules and we won't have too much to worry about. But there will still be adjustments to make.
Throw in the fact that autonomous vehicles will be significantly more efficient and thus drastically better for our environment, and this all sounds pretty exciting! Here's hoping the self-driving future arrives sooner rather than later.

We’ve now uncovered more details on how Tesla achieved such drastic improvements in the vehicle’s power consumption, which Tesla estimated to be a 40% reduction.
Tesla made architectural changes to how it processes and analyzes video — optimizing which components handle which tasks. While the Cybertruck is the first to benefit from these advancements, Tesla plans to extend these upgrades to other vehicles in the future.
Sentry Mode Power Consumption
Tesla vehicles feature two main computers: the MCU (Media Control Unit) computer, which powers the vehicle’s infotainment center, and the FSD computer, which is responsible for Autopilot and FSD. Both of these computers remain on and powered any time the vehicle is awake, consuming about 250-300 watts.
Typically, the vehicle only uses this power while it’s awake or actively driving. It’s not a major concern since the car automatically goes to sleep and shuts down its computers after about 15 minutes of inactivity. However, the larger issue is that these computers also need to remain on when Sentry Mode is active, causing a 250-watt draw whenever Sentry Mode is on.
Interconnected System
Today, the vehicle’s cameras are connected to the FSD computer, which connects to the MCU, which is finally connected to the USB ports. Because of this interconnected setup, everything needs to remain powered. Footage needs to be streamed from the FSD computer into the MCU, where processes like motion detection occur. The data then needs to be compressed before finally being written to the USB drive. That’s a lengthy process, requiring multiple computers to remain on in order to be able to record and save live video.
Architectural Changes
Tesla is making some architectural changes to address Sentry Mode’s high power consumption by shifting the responsibilities of the vehicle’s computers. By shifting motion detection and possibly the compression activity to the FSD computer, Tesla will now be able to keep the MCU computer asleep. The MCU is still required to push the video to the USB drive, but Tesla can now wake up the system only when it’s needed.
For instance, the FSD computer will still handle the connection to the vehicle’s cameras, but it will now also detect motion. When that Sentry event occurs, it can wake up the MCU to write the data to the USB drive and then have it go back to sleep.
This approach ensures the MCU isn’t continuously powered to analyze and compress video, instead activating it only when data needs to be written.
Processor Isolation & Task Allocation
Tesla’s current architecture separates the Autopilot Unit (APU) from the MCU. This is done for several reasons - but first and foremost is safety. The MCU can be independently restarted even mid-drive without impacting the APU and key safety features.
Additionally, by isolating the APU from the MCU, tasks that are optimized for each unit—processing versus image transcoding—can be offloaded to the processing unit that’s better suited for it. This helps keep both the APU and MCU operating at their optimal power and performance parameters, helping to manage energy consumption more efficiently.
Kernel-Level Power Management
Tesla’s been working on more than just FSD or new vehicle visualization changes and has been putting in the effort to optimize the operating system’s underlying kernel. While not in heavy use, Tesla is underclocking the processors of both the MCU and APU, reducing power usage and heat generation.
Of course, other kernel optimizations and programming tricks, such as the ones Tesla uses to optimize its FSD models, also factor into the increased overall efficiency of the vehicles.
Additional Benefits
Since Tesla vehicles also include a Dashcam that processes video, it’s possible we may also see these additional power savings whenever the vehicle is awake. This could also affect other features, such as Tesla’s Summon Standby feature, which keeps the vehicle awake and processing video to give users almost instant access to the vehicle’s Summon feature.
Roll Out to Other Vehicles
While the Cybertruck was the only vehicle to receive these power improvements to Sentry Mode, we were told that they’re coming to other vehicles too. Tesla is introducing these changes with the Cybertruck first, leveraging its smaller user base for initial testing before expanding the rollout to other vehicles.
USB Port Power Management
To further conserve energy and reduce waste, Tesla now powers down USB ports, even if Sentry Mode is active. This change has impacted many users who rely on 12v sockets or USB ports to remain powered to keep accessories such as small vehicle refrigerators on.
It’s not immediately clear whether these changes to Sentry Mode impact this change or whether power to 12v outlets was removed strictly due to safety concerns.
Tesla has initiated another minor design revision, this time improving the rear camera on the Model 3 and Model Y. This minor revision adds a protective lip around the camera, providing better shielding against rain, dirt, snow, and general road grime.
The design revision began rolling out for Model Y vehicles from Shanghai first, with the initial vehicles spotted with the revision dated as early as late September 2024. Tesla regularly makes minor design revisions on its vehicles in between model years, in an iterative design process that gradually improves as more and more vehicles are built.
Design Revision
The design revision adds a small shield around the rear camera, including a small lip towards the bottom end. The little lip is likely going to make the biggest difference, as it will help prevent kickback and wash from the tires landing on the camera lens, which can obscure it.
For now, nothing indicates a potential revision including a camera washer—similar to the Cybertruck’s front camera washer. However, given we already know the Model Y Juniper is likely arriving with a front camera, it’ll probably also have a front camera washer.
This lip for the rear camera should be a nice addition, but we’ll have to see just how much of an improvement it provides in the upcoming winter season as the messy, slushy mix arrives in much of the United States and Canada.
3D Printed Accessory
If you’re feeling left out without the new rear camera shield, you’ll soon be able to 3D print and install a similar design. Some entrepreneurial 3D modelers have already started working on making a retrofittable shield for both the HW3 and HW4 rear cameras.
In the meantime, we recommend using ceramic coating on the rear camera to help keep that slush and grime moving when it does hit the camera. A good application of ceramic coating can help prevent buildup on the lens.
Model S and X
For now, we haven’t seen this design revision on more recent Model S and Model X vehicles yet. There were previously rumors of a light refresh for both of the more premium vehicles. However, we haven’t seen any indications of these changes actually seeing the light of day.
Once the refreshes for these two vehicles arrive, we could see more drastic changes. Tesla has also indicated it is waiting to use some of its upcoming new battery cell technology in 2026, so we could be waiting for a while before seeing further updates to the Model S and Model X.
We’ll be looking for both vehicles to receive this design revision. If you spot them, let us know on social media or on our forums.
