When purchasing a Tesla you’ll come across the terms “Autopilot” and “Full Self-Driving” (aka FSD) and may wonder what the difference is, especially since the Full Self-Driving package is rather expensive. In this article, break down the differences between Autopilot vs Full Self-Driving to help you decide for yourself whether FSD makes sense for you.

The Autopilot and Full Self-Driving Lineup
The Tesla driver assistance features include the following two tiers below. There used to be a tier called “Enhanced Autopilot” but that has since been deprecated (see Autopilot vs. Enhanced Autopilot) and those features have folded into the current tiers here:
- Autopilot – This is basic driver assistance as found in most other cars with autopilot today. It’s included with all vehicles.
- Traffic-Aware Cruise Control. (TACC) This stop-and-go dynamic cruise control will follow other cars, stop in traffic and automatically resume.
- Automatic Steering / Lane Centering. This keeps the vehicle in the lane when used with TACC above.
- Full Self-Driving (FSD) – This option contains the autonomous driving features that are generally more exclusive to Tesla. Pricing: $7,000 as of this writing.
- Auto Lane Changes. When using both TACC + Automatic Steering, a driver can use the turn signal to automatically change lanes when it’s clear.
- Navigate-on-Autopilot. When a destination is entered, the vehicle can fully navigate itself to the destination (currently only on freeways from on-ramp to exit and with a confirmation for lane changes).
- Summon. Allows the vehicle to be summoned from its current location to another location nearby (in private parking lots, for example).
- Autopark. This allows the vehicle to park itself in both parallel and perpendicular spots.
- Traffic Light & Stop Sign Recognition. Currently alerts you at the last moment if there is a stop sign or traffic light (will not stop the vehicle) while on Autopilot.
- Automatic City Driving. Future feature, TBD what this means exactly.
Standard Active Safety Features
All new Tesla vehicles built after 2016 come with a suite of sensors around the vehicle, including cameras, ultrasonic sensors and radar that allow the vehicle to understand and react to its environment (see AP1 vs AP2 vs AP3 for hardware differences). Using a powerful computer and software, the vehicle comes standard with the following free active safety features:
- Lane Assist
- Collision Avoidance Assist
- Speed Assist
- Auto High Beam
These core safety features are somewhat similar to ones found standard on other vehicles, but with additional ‘intelligence’ built-in and continually improved via Tesla over-the-air software updates (something no other auto manufacturer currently does). Before the March 2019 Autopilot renaming, these were confusingly referred to as ‘standard Autopilot’, but now are simply included with the vehicles.
Here’s a breakdown of each one.
The Tesla Lane Assist feature does three things:
- Alerts you if you drift from your lane (called Lane Departure Warning, similar to traditional Lane Keeping Assist functions)
- Warns you if there’s an object in your blind spot (like Blind Spot Monitoring in other cars)
- Intervenes if it believes you may drift into an adjacent object when driving between 30 and 85 mph.
Of the three features above, only Land Departure Warning is an option. When turned on, it will vibrate the steering wheel when it believes you are drifting out of the lane. You can turn this on and off in the Tesla Settings menu under Controls > Autopilot > Lane Departure.
The Tesla blind spot warning feature will turn the lanes on the display red if it detects an object in the blind spot when you turn on the blinker.
Finally, the steering intervention functionality will automatically steer the vehicle into a safer position within the driving lane if it detects that a potential collision with an adjacent vehicle is imminent (for example, if you accidentally drift into a lane with a car in it). It only works between 30 and 80 mph on major roadways where the lane markings are clearly visible.
Collision Avoidance Assist
The Collision Avoidance Assist portion of standard Autopilot functionality provides the following features:
- Forward Collision Warning – this provides an audible and visual warning if the vehicle determines there is a high risk of a frontal collision.
- Side Collision Warning – this warns the driver of potential collisions along the side of the vehicle.
- Automatic Emergency Braking – this will automatically apply the brakes if there is an imminent frontal collision to help reduce or avoid impact.
- Obstacle-Aware Acceleration – this reduces the vehicle’s speed if it detects an object in it’s driving path
Forward Collision Warning portion of Autopilot will not only detect vehicles, but also motorcycles, pedestrians and bicyclists. It utilizes the sensors and cameras placed around the vehicle, plus the sophisticated neural network used by Tesla to identify objects. The Forward Collision Warning is the first alert to the driver, and if no action is taken the other systems such as Automatic Emergency Braking come into play.
Side Collision Warning is similar to Forward Collision Warning above but monitors the side of the car. In some cases, it will actually apply steering to avoid a collision, if possible.
Automatic Emergency Braking (AEB) works by utilizing the forward looking cameras and radar to determine if a collision is imminent. If a collision is considered unavoidable, Tesla AEB will apply the brakes to reduce the severity of impact, or avoid it altogether, if possible. It works between 7 mph and 90 mph.
Obstacle-Aware Acceleration is meant to reduce the impact of a collision by reducing motor torque. What does that mean? If the vehicle detects an object in its path while you are pressing the accelerator pedal, it will reduce the power to the motors to mitigate potential damage to the vehicle and object. For example, if you intend to back out of your garage, but accidentally put the vehicle in forward Drive, it will detect an object in front and reduce speed to reduce damage.
Speed Assist uses GPS data and speed limit signs to help determine the car’s position and what the speed limit should be. Using that information, it can optionally be set to warn the driver on screen or via a Chime if you’re exceeding the speed limit. On the Model 3, you can also press the displayed speed limit sign on the touchscreen to automatically set the speed to the current speed limit.
Auto High Beam
Auto High Beam will automatically turn High Beams on or off depending on the surroundings. If the vehicle detects there is enough light or another car is approaching, it will turn off High Beams. Conversely, if it is sufficiently dark, it will automatically turn on High Beams.
This is a “beta” feature that truly hints towards autonomous driving capabilities of the future. It allows the vehicle to fully navigate itself on ‘closed-access’ freeways or highways (meaning those that have on-ramps and off-ramps and no cross-traffic intersections). Once you enter a destination into the navigation system and engage Autosteer, you’ll have the option to press the “Navigate on Autopilot” button. This will then follow the optimal path on the freeway, automatically changing lanes (with driver confirmation currently) and navigating freeway interchanges as needed.
Autopilot is a standard feature that allows a vehicle it steer itself and automatically accelerate and brake for other vehicles and pedestrians within its lane.
This is similar to other cars today that have Stop-and-Go Assisted Cruise Control plus Lane Centering (see Cars with Autopilot). However, in Tesla’s case the system is far more powerful and accurate, using cameras all around the vehicle and AI computing hardware. In addition, updates are made continually over the air – something no other manufacturer currently offers.
Autopilot provides these core features:
Traffic Aware Cruise Control (TACC)
This feature is similar to what’s often called stop-and-go Dynamic Cruise Control in other cars. It allows you set a speed and following distance to other cars and will then automatically speed up or slow down depending of the speed of the vehicle in front of you. It works at all speeds up to 90 mph and in stop-and-go traffic. It’s a real life-saver during rush-hour commutes.
Autosteer (Lane Centering)
Once the Autopilot system detects clear lane markings, it will allow the driver to engage Autosteer that works in conjunction with TACC above. This allows the vehicle to steer itself as long as conditions allow and the driver has their hands on the wheel (the driver must still pay attention).
Full Self-Driving Features
Full Self-Driving has more advanced assisted and semi-autonomous driving capabilities than found in the basic Autopilot package.
A Brief History of Full Self-Driving…
Full Self-Driving was a feature long-promised from Tesla since Autopilot was originally introduced years ago. Initially, the notion was that Autopilot features would provide more of the ‘assisted driving’ features such as TACC, automatic steering, summon, etc. whereas Full Self-Driving would provide ‘autonomous’ driving capabilities, similar to Waymo (Google’s self-driving taxis).
However, it soon became clear that true autonomous driving would be years off, so Tesla changed the lineup so that Autopilot is now a basic set of assisted driving features and ‘Full Self-Driving’ has more advanced capabilities.
Here’s a breakdown of what’s currently in Full Self-Driving:
Auto Lane Changes
While Autosteer and TACC are active, you can have the vehicle change lanes automatically once it’s safe to do so by turning on the blinker towards the desired lane to which you’d like to switch. The vehicle will review the surroundings and make the lane change once it’s safe to do so. This is arguably the valuable feature in the FSD option set as makes lane changes safer, less stressful and allows you to avoid having to disengage and re-engage Autopilot.
Navigate On Autopilot
It’s considered fully automated “on-ramp” to “off-ramp” technology and is quite amazing and unlike anything else available for consumer use. It will even automatically suggest changing to faster lanes if it finds traffic moving more quickly in adjacent lanes. That said, it’s still in “beta” so you have to pay close attention while in use.
The Autopark feature allows the vehicle to automatically park itself in both parallel and perpendicular spots, as long as other cars are nearby. While many auto manufacturers offer something similar, Tesla’s version handles all the steering acceleration and braking, making it truly hands-off. It’s still a bit hit-and-miss, with most people not using very often.
Summon (and Smart Summon)
One of the most unique features offered by Tesla is the Summon function. It allows you to remotely summon the vehicle out of tight parking or garage spaces, for example.
Tesla recently updated Summon to include “Smart Summon”, allowing the vehicle to navigate more complex routes, even summon to you in private parking lots, for example. But again, this is very much a “beta” feature and not very practical until the cars become better at self-driving.
Future Autonomous Full Self-Driving Capabilities
Tesla has promised a couple of other Full Self-Driving features that will likely be deployed in late 2020, according to Elon Musk during Tesla’s 2019 Autonomy Day. These include:
- Traffic light and stop sign detection, plus the ability to respond to them appropriately
- Automatic driving on city streets
What automatic driving on city streets means exactly remains to be seen, but it will be exciting to see these new capabilities rolled out, especially with Hardware 3 now included in all new cars and rolling out to previous models that support it.
Is Full Self-Driving Worth the Cost?
Ok, so here’s the $7,000 question – is the Full Self-Driving (FSD) package worth the cost? In short, for most people, the answer is currently no.
While Navigate-On-Autopilot and Smart Summon are currently neat demo features, they aren’t robust and reliable enough to make them practical. The primary feature that is used most often from FSD package, is Auto Lane Change. This is truly a useful safety feature that makes lane changes on the highway safer, but that’s a lot for $7K!
The big promise for Full Self-Driving, of course, is that we’ll see more autonomous self-driving features roll out in 2020, according to the Tesla 2019 Autonomy Day summit. Keep in mind, however, that most experts think that’s a stretch.
That said, there’s no doubt the driver-assistance features will continue to improve in the Full Self-Driving package and if getting those updates is important to you, then the package may be worth the price.
