Tesla Autopilot: Difference Between Basic Autopilot, Enhanced Autopilot and FSD

Depending on your region, Tesla offers two or three Advanced Driver Assistance Systems (ADAS). They may be available as a one-time purchase or as a subscription model.

Autopilot, the basic package, is now available for free on all Tesla vehicles. However, that hasn’t always been the case and if you’re buying a used Tesla, it may not come with Basic Autopilot.

Enhanced Autopilot offers a few additional features, but its availability will vary depending on the market. It has previously been available for purchase in North America, but it’s currently unavailable as Tesla tries to push more people toward the now cheaper FSD option.

Finally, FSD—or Full Self-Driving—is Tesla’s capstone feature. It allows its vehicles to drive to most locations without a driver intervention but requires constant supervision.

We’ll break down each of the three offerings and what they include below.

Basic Autopilot

Tesla’s standard offering is Basic Autopilot. It comes on every new vehicle for free (since about 2019), and there are no additional charges for it. Autopilot consists of two key features, “Traffic-Aware Cruise Control” and “Autosteer”.

Alongside these features, Tesla offers a whole host of safety features, such as Automatic Emergency Braking, that are included with every vehicle. Some vehicles may require HW3, which was launched in 2019.

Traffic-Aware Cruise Control

Traffic-Aware Cruise Control, or TACC, as it is more commonly known, is enhanced cruise control. The driver is still steering, but TACC automatically adjusts the vehicle's speed to maintain the following distance from vehicles in front.

TACC is initiated with one downward tap of the right steering stalk. If the vehicle includes FSD and it is enabled under Controls > Autopilot, it must be turned off before TACC is available.

TACC following distances can be adjusted by pushing the right scroll wheel on the steering wheel or yoke to the left or right. You can adjust TACC’s speed (up to +10mph or +10km/h above the posted limit on non-highways) by scrolling the same wheel up and down.

Autosteer

Autosteer is essentially an enhanced lane-keeping system. It works in conjunction with TACC to keep the car in the marked (or unmarked) lane. It is functional at any speed above 10 mph or 15 km/h but will not stop for stop signs or lights. This is important to keep in mind, as Autosteer is extremely useful but will not obey any traffic control signs, perform turns, or change lanes. It requires full driver supervision at all times.

Autosteer functions on both surface roads and highways, with no limitations on surface roads other than the same limits that apply to TACC on surface roads regarding maximum speed. Autosteer can greatly help reduce driver fatigue, and drivers can take over whenever they need to turn, use an off-ramp, or encounter a traffic control like a stop sign or traffic lights.

One of the coolest things you’ll notice on Autopilot, whether on the highway or on a regular road, is that it will provide extra space for larger vehicles – it will move over within the lane to ensure that adequate space is maintained. This is also beneficial to cyclists, who are provided the correct 5 ft (1.5m) distance between them and a vehicle. Don’t be scared if your Tesla moves to the edge of the lane to give them a little space.

Park Assist

Not a Tesla App

Tesla's Park Assist feature (video) provides a 3D reconstruction of the vehicle's surroundings while parking, similar to a 360-degree camera but with 3D models built in real-time.

The system leverages Tesla Vision to create the surrounding environment, including cars, pillars, bikes, and other nearby objects. It may not recognize all the objects, but it can define their outlines and build a 3D model.

Each 3D model is gray, but changes color the closer the vehicle gets to the object. The objects go from gray to yellow, orange, and finally red.

Since these are actual 3D models, you can even pan and rotate the on-screen models to view them from various angles.

The new Park Assist feature is available on all vehicles powered by AMD Ryzen chips. Tesla started adding AMD Ryzen chips in early 2022, but you can confirm your vehicle’s infotainment chipset by navigating to Controls > Software in the vehicle and tapping on Additional Vehicle Information. Here, you’ll be able to see if your vehicle has the Intel Atom chip or the AMD Ryzen chipset.

For vehicles with Intel chipsets, your car will display distances to objects using its ultrasonic sensors instead of a 3D visualization of the objects on the screen.

Enhanced Autopilot (EAP)

Enhanced Autopilot was a purchase option and even a subscription feature available in some regions. However, it is no longer available for purchase in North America, but it is still available for those owners who previously purchased it. For owners who have purchased EAP, it is also still available.

Enhanced Autopilot adds some convenience features on top of the Basic Autopilot functionality that improves highway driving and helping out in parking lots.

EAP was previously available for $6,000 USD or $7,800 CAD.

Auto Lane Change

Auto Lane Change is just what it sounds like. While on Autopilot and on a multiple-lane road or highway, Autopilot will automatically change lanes to maintain the set speed, if possible. This means it will switch lanes to pass other cars on the road that are driving slower than your set speed limit.

Definitely a great convenience feature for road-tripping.

Navigate on Autopilot

Navigate on Autopilot is an enhancement for Autopilot on highways, taking Auto Lane Change up another notch. It lets your Tesla take control and manage on-ramps and off-ramps, and most importantly, it will change lanes for you to make sure your vehicle is in the correct lane for you to get off the correct exit, onto the next highway or move away from an exit-only lane. This is an excellent feature in a bigger city that you may be unfamiliar with, as it makes sure you’re in the correct lane to stay on your route.

Navigate on Autopilot will automatically signal and take the off-ramp to your navigation destination, handing over control to the driver near the end of the onramp.

Navigate on Autopilot will both visually and audibly ping the driver to take over once it has reached the end of the off-ramp, and the driver is expected to take control for the turn off the ramp. Auto Lane Change will put you in the correct turn lane before it pings for control takeover.

Once again, similar to Autosteer, Navigate on Autopilot is not able to manage traffic controls or turns, which means it will require the driver to take over once it is done. Just like every other autonomy feature from Tesla today, this requires driver supervision.

Autopark

Not a Tesla App

With EAP, your Tesla can reverse park or parallel park itself, thanks to Autopark, which is now available for Tesla Vision vehicles. Autopark was recently revamped, making it faster and more reliable. Tesla is also expected to add Park Seek as part of EAP in a future update.

When driving slow enough (below 6mph or 10km/h), parking spots will appear on the visualization, letting you select a spot. The vehicle will ask to be brought to a stop, and then you can tap the screen (or confirm with the buttons on a Model S or X), and the vehicle will begin parking.

Enjoy this moment as your Tesla parks itself hands-free. While you can release the seatbelt during Autopark, you should always supervise your Tesla while it is moving on its own, as it is not perfect and will occasionally need the driver to intervene.

Summon

AIDRIVR

Summon has two options; one allows you to move the vehicle backward or forward using the Tesla app on your phone, enabling you to get in and out of tight parking spaces like those in a parking garage. Summon has a maximum distance of 39 ft (or 12m) in either direction of the starting position.

The other option, Smart Summon, will bring your car to you in a parking lot or driveway, letting it automatically switch between forward and reverse, make turns, and stop for obstacles. For Smart Summon to function, you need to be within approximately 215 ft (65m) of your vehicle. It will exit the parking spot and then drive towards you.

However, Smart Summon is currently limited to vehicles with ultrasonic sensors (USS). Tesla has already started rolling out a new version of Smart Summon called Actually Smart Summon that will make it available on all Tesla vehicles. Actually Smart Summon is currently available in North America on recent builds of FSD, but it’s expected to be more widely available later this year.

Summon is in beta and should be carefully supervised. We highly recommend that you do not use Smart Summon in a busy parking lot until the Actually Smart Summon update is deployed.

Full Self Driving (Supervised)

FSD (Supervised) is the current top-end package for Tesla’s autonomy. It is available with a monthly subscription in North America at $99 USD / $99 CAD, or for purchase at $8,000 USD or $11,000 CAD. The United States also has an annual subscription option that offers a slight discount, but that option is currently unavailable in Canada.

FSD allows your Tesla to drive from point A to point B almost entirely on its own, with the driver supervising it. One thing to keep in mind is that the software stack that governs FSD on city streets and the one that governs Autopilot on the highway is fairly different, with city streets including more advanced capabilities. However, this is expected to change in the near future as Tesla adds support for the highway to its FSD tech stack.

We recommend subscribing for a month and trying it out – or you may have already received a free month of FSD as a trial.

The FSD package includes everything in Enhanced Autopilot, city street driving and a few additional options, such as Green Traffic Light Chime, which has the vehicle beep when a traffic light turns green if your vehicle hasn’t moved in about a second.

FSD (Supervised)

FSD V12, also known as FSD (Supervised), is the latest version of Tesla’s Full Self Driving package. It is capable of tackling most situations that a driver can encounter. However, as with all autonomy products, it isn’t perfect and needs driver supervision – hence the “Supervised” in the name.

FSD is fairly simple for the user – set a navigation destination and tap down once on the right steering stalk, and FSD will take over driving. You must always remain attentive of the vehicle and be prepared to stop it in a dangerous situation.

FSD will stop for stop signs and traffic lights, maneuver between lanes as necessary, and take all the turns you need to take. It can handle encountering things like road construction, 2-way stops, 5-way intersections, and much more with the driver supervising it. For the most part, with recent versions of FSD, you won’t need to intervene often while driving.

FSD will take you to your destination, and depending on where that is, it may bring you directly to your driveway or right into a parking lot, where you can then enable Autopark to park your vehicle.

Tesla’s Hollywood Diner: In-Car Controls & Theater Screens Turned On [VIDEO]

By Karan Singh

Tesla has been quietly building something pretty unique on the streets of Hollywood—and we’ve been keeping a close eye on it. That’s right: the long-anticipated Tesla Hollywood Drive-In, Diner, and Supercharger is shaping up to be one of the most creative approaches to EV charging yet.

But this isn’t your average Supercharger site. It features a retro-futuristic, 24-hour diner and an outdoor movie theater, blending the charm of the 1980s with the tech-forward vibe of the 2020s.

Construction has been underway for quite some time, with the Cybertruck-inspired stainless steel structure going up around mid-2024. And more recently, we spotted hints in the Tesla app that the Diner’s debut is getting close.

Diner Controls in App / Car

Tesla hacker Greentheonly managed to spot some new evidence of changes within Tesla’s 2025.8.6 software build, which includes a new modal for “Charger Diner Controls”. While there isn’t anything to activate this new modal just yet, it is an indication of how Tesla intends to integrate the experience right into each and every Tesla.

The text in the modal reads: “Plug in, place your order, recharge” - which means that once you arrive and are plugged in, you’ll be able to place your order - and likely pay through Tesla’s payment system. It seems like this will all be done through either the Tesla app or the vehicle’s tocuh screen. No need to fumble with a separate app or pull out your wallet.

This is definitely a level of integration you just can’t have anywhere else - and just like any other Supercharger site, the Tesla Diner will appear as a suggested site for charging when you’re navigating or looking around the Hollywood area.

45-Foot Screens Ready

Those two absolutely gigantic 45-foot LED screens have now been turned on for the first time, meaning that Tesla is likely close to opening the Supercharger site. The screens were spotted displaying some test patterns, as well as some Tesla-themed content. It really brings the construction site to life - and it's the clearest sign that the Diner is well on its way to completion.

We’re hoping that this first Tesla Diner sees plenty of success - and that Tesla begins opening more of these types of facilities throughout North America, and eventually globally. Given Tesla’s penchant for unique Superchargers, we imagine this could truly be the case one day.

Tesla’s FSD V13 Pushes HW4 Hardware Capabilities; End of Line for HW3?

By Karan Singh
Not a Tesla App

As Tesla continues to push the capabilities of its hardware as it prepares for autonomy with FSD Unsupervised, there has been a distinct divergence in features between HW4-equipped vehicles on FSD V13, and HW3-equipped vehicles on FSD V12.6. 

There are definitely reasons for this, and Tesla hacker Greentheonly, over on X, went into great detail on some of the reasons why this divergence has continued and is likely to continue.

If you’re interested in some background, we recommend the following articles. Although they’re not necessary, you may enjoy reading them before diving right in if you enjoy this topic.

Back in the summer of 2024, we reported that Tesla’s HW4 had yet to reach its full potential, and that HW3 still had some compute to work with. However, FSD has undergone a rapid evolution - there are now fundamental differences driven by the hardware capabilities and sheer scale of the latest builds of FSD.

FSD V13’s Gargantuan Neural Networks

FSD V13 is a substantial leap for Tesla. It features substantially larger neural networks - the core brain that processes all the environmental data and makes decisions. Those networks are far larger in V13 than in V12, which results in a much smoother and human-like expereience.

Tesla’s FSD computers contain two nodes. According to Green’s analysis of FSD V13, Node B, which handles the actual end-to-end driving logic, tripled in size from 2.3 GB in V12 to a staggering 7.5 GB in V13. That’s a substantial increase, and one of the main reasons why HW3 can’t handle FSD V13. While Interestingly, Node A on HW4 remains similar in size to FSD V12, using up about 2.3 GB.

However, this massive size is also pushing the limits of HW4. While this isn’t necessarily a big problem immediately - at the end of the day, there is a limited amount of compute and ram available and model sizes will likely grow in the future. In fact, Tesla is planning to scale model sizes in the next FSD version and has already said they’ll need to optimize them, as context size is limited by on-board memory.

HW3 Limitations

Since HW3 can’t run the latest FSD models, where does this leave millions of Tesla vehicles equipped with the now-legacy FSD hardware? Are they hitting a dead end? Not exactly - Tesla has promised to replace HW3 computers with new units during the Q4 2024 Earnings Call, but only for those who have purchased FSD and only if Tesla is no longer able to update HW3 vehicles.

There’s no doubt Tesla hopes to achieve autonomy and then work backwards to make it compatible with HW3, but that’s unlikely to happen with the limited ram available on HW3.

Tesla’s AI team has continued to say that they’re still working on updating HW3 vehicles - but that they will be taking a backburner to updates for HW4 until the team can optimize the model efficiently enough to run on the smaller footprint. That means V12.6 isn’t just V13 “lite” - it is a distinctly different software branch tailored specifically for HW3’s capabilities.

Green's analysis showed that HW3 under V12.6 runs NNs totaling 1.2 GB on Node A and 3.1 GB on Node B, which is significantly smaller than the footprint of V13. Back in November, we discussed how Tesla is running a smaller and optimized FSD model on HW3, with the specific goal of achieving similar performance to V13. FSD V12.6 appears to be the current implementation of that smaller model strategy.

Green also found that of the total neural nets used for FSD, 135 are shared between the current V12.6 and FSD V13.2 releases, which is the result of Tesla’s AI team working to optimize and refine the V13 model for HW3. So some neural nets are shared between the two sets of hardware, while others are specific to HW3 or HW4.

AI4 in the Future

The fact that V13 is already stretching HW4’s limits makes us wonder about Tesla’s imminent release of AI5. Last year, Tesla mentioned that AI5 would be 18 months away - which is now about 8 months away, and potentially even sooner to help solve the autonomy problem.

At the same time, Tesla is looking to launch Unsupervised FSD in June in Austin, Texas, with presumably HW4, which would indicate that they’re confident in its capabilities.

Unless Tesla launches the Robotaxi network with AI5, we don’t believe AI5 will be a “must have” item. Undoubtedly, it will result in similar improvements to HW4 compared to HW3. However, the software needed to take advantage of the newer hardware could still be years away.

All eyes will be on Tesla’s Robotaxi network launch and the hardware required for it. For now, HW4 owners are in good hands with future updates are on the horizon, and we’re certainly excited for what’s next.
