- Tesla Full Self-Driving (FSD) is an advanced autonomous assistance system that is constantly evolving and seeks to reduce human intervention.
- The technology is based on hardware own, neural networks and camera vision, without relying on LiDAR sensors, differentiating Tesla from other manufacturers.
- Currently, FSD requires constant driver supervision and faces technical and regulatory challenges before achieving full autonomy.
Tesla's progress toward fully autonomous driving has revolutionized the automotive world. Promises of virtually self-driving vehicles, the elimination of human error, and much more efficient urban mobility have captured the attention of both drivers and technology experts. However, many questions arise about what the Full Self-Driving (FSD) system actually is, how it works today, and to what extent it can be fully trusted.
We will dedicate this article to explaining in detail how Tesla Full Self-Driving works, its key features and how to use it.We'll also review the technical components Tesla uses to distinguish itself from other autonomous vehicle manufacturers, the challenges the brand faces, and future prospects within the current technological and legal ecosystem.
What is Tesla Full Self-Driving (FSD)?
Tesla Full Self-Driving, widely known as FSD, is the name given to the advanced software package developed by Tesla to equip its electric vehicles with autonomous driving functions beyond what the standard Autopilot offers.Its goal is to minimize and even eliminate human intervention during driving, increasing road safety and offering a completely different driving experience than ever before.
The FSD aims to achieve level 4 autonomy according to the SAE (Society of Automotive Engineers) classification, which means that The vehicle will be able to handle all driving tasks in most situations and environments, although it may require some occasional supervision.Level 5 would represent the maximum degree of automation, where the car would be completely autonomous and no driver would be required, but there is still a long way to go to reach this point.
How is FSD different from conventional Autopilot?
One of the most confusing aspects is the difference between the standard Autopilot and the Full Self-Driving package. Basic Autopilot allows you to keep your car in your lane and control your distance from other vehicles (adaptive cruise control).However, the FSD version includes much more advanced features such as:
- Automatic city driving, with traffic light and stop sign detection.
- Autonomy to decide turns and detours left and right according to the route marked on the navigator.
- Ability to navigate roundabouts, cross intersections, and adapt to new traffic signals.
- Automatic lane change on the highway.
- Autonomous entry and exit to parking lots using the "Smart Summon" function.
The set of these functionalities makes FSD a much more complete and complex tool than Tesla's traditional autopilot..
The technical heart of the FSD: proprietary hardware and software
Tesla has made a strong commitment to vertical integration, developing both the hardware and software that make up its FSD system. In 2019, Elon Musk unveiled the brand's first self-driving supercomputer designed from scratch. This system, also known as Hardware 3.0, displaced the solutions of Nvidia previously used and was based on a self-produced chip, manufactured in collaboration with Samsung under a 14-nanometer FinFET CMOS process.
The FSD chip includes two independent processors that They allow redundancy and increase operational safety. Everyone has their own memory, storage and power supply. Thanks to this dual architecture, the system can constantly verify that driving decisions are correct by comparing the route plans from both processors before executing them.
Of particular note are the on-chip neural network accelerators, designed to process huge volumes of data in real time, recognizing shapes, objects and situationsThis hardware can achieve over 144 TOPS (Tera Operations per Second), putting it far ahead of other solutions in the industry. It also includes advanced security features, such as dedicated video encoders and modules that only run code signed by Tesla, preventing the risk of hacking.
The exclusive commitment to vision: cameras and sensors
One of the features that radically differentiates Tesla's FSD from other autonomous driving systems is its decision to discontinue the use of LiDARWhile many manufacturers opt for this laser sensor that measures the distance to objects, Tesla has opted for a system based exclusively on cameras, radar, and ultrasound, emulating the way humans perceive the environment.
Each Tesla equipped with FSD integrates several cameras that cover all angles of the car, ultrasonic sensors for nearby objects and radars to measure distances and speeds.. The software uses Artificial Intelligence and deep learning to interpret and predict the behavior of traffic, pedestrians, and other vehicles, even identifying signs and traffic lights.
This approach, although controversial, has proven effective in a variety of environments, although it presents challenges in highly complex urban situations or in adverse weather conditions. Artificial intelligence and deep learning play a fundamental role in the evolution of the system.
How do you use the Full Self-Driving system in a Tesla?
Using the FSD is designed to be simple and accessible to any driver familiar with the Tesla interface. To activate the advanced features of FSD, you must have subscribed to the corresponding package, either through a one-time purchase or a monthly subscription.Once the package is confirmed, some of the most notable features that can be used are:
- Navigate on Autopilot: allows the car to guide the entire route on highways and expressways, including entrances, exits, and automatic lane changes for overtaking.
- Recognition of traffic lights and stops: The Tesla can identify lights and stop signs, braking and starting autonomously under supervision.
- Smart parking: The car searches for spaces and performs parallel or bay parking maneuvers without the user's assistance.
- Smart Summon: allows the car to leave the parking space and go to the owner without anyone being inside.
All of these functions require the driver to maintain attention and keep their hands close to the steering wheel. Since, legally, the responsibility remains with the user until the legislation changes and the level of autonomy is accepted by regulators.
Continuous updates and improvements to the FSD software
One of the great strengths of the FSD system is that Tesla frequently updates its software remotely.. Thanks to the OTA updates (Over The Air), users receive performance improvements, new features, and bug fixes without having to go to a repair shop.
Feedback gathered from thousands of drivers, especially those participating in the beta program, It is vital for the evolution of the systemEvery mile traveled, every error detected, and every successful maneuver feeds Tesla's proprietary algorithms, which learn and optimize using big data and neural networks. If you want to better understand how these advancements are driven, you can delve deeper into them here.
Recent versions such as FSD 12.3 and 12.4 have shown significant progress in certain tasks, but also some setbacks in others. Cases have been documented where the car reacts more hesitantly in urban settings or requires more input compared to previous versions, especially during tests in densely populated cities.
Limitations, current challenges and testimonials about FSD
Although progress is evident, the FSD still has limitations. Unpredictable situations such as other drivers' maneuvers, sudden changes in the road, obstacles or misinterpreted signals can cause the car to request driver intervention.. Recent testimonies indicate that while the system has improved over time, There, still exhibits unsafe behavior at complex intersections, uncertain turns, or when other vehicles abruptly invade the path.

Developers and Tesla insist that Human surveillance must be maintained until official certification of full autonomy is achieved.. Regulation in different countries and regions also presents significant challenges, as Tesla needs to demonstrate that its system can respond appropriately in all possible environments..
