Full self-driving (FSD) and autonomous vehicles enable cars to navigate and operate without human intervention. That is, a person need not be there to drive the vehicle. In reality, however, the term "full self-driving" can be misleading, as it typically indicates advanced driver-assistance systems rather than complete autonomy.
What is Full Self-Driving?
Full Self-Driving (FSD) is an advanced driver assistance system (ADAS) that allows vehicles to perform certain driving tasks autonomously while still requiring driver supervision. FSD was popularised by Tesla. It uses a combination of hardware, such as cameras, sensors and advanced software to enable features like:
Navigate on Autopilot: Assists with highway driving tasks, including lane changes and exits.
Traffic and Stop Sign Control: Automatically slows down or stops for traffic signals and stop signs.
Autosteer on City Streets: Provides steering assistance in urban environments.
Summon: Moves the car to a specified location within a parking area.
Despite these capabilities, FSD does not equate to full autonomy; drivers must remain attentive and ready to take control at any moment.
Is it really fully autonomous?
The Society of Automotive Engineers (SAE) categorizes vehicle autonomy into six levels, from Level 0 (no automation) to Level 5 (full automation). Levels 3 to 5 represent varying degrees of self-driving capabilities.

Autonomous driving kicks in from level 3.
Currently, no vehicles on the market achieve Level 5 autonomy, and most existing systems, including Tesla's FSD, still require driver oversight.
Challenges of FSD
The development of fully autonomous vehicles faces numerous challenges, including regulatory hurdles, technological limitations, and safety concerns. Manufacturers must conduct extensive testing to ensure that self-driving systems can handle a wide range of driving scenarios safely. As technology advances, the aim is to reduce human error in driving and enhance overall road safety.
Summary
In summary, while full self-driving technology represents a significant advancement in automotive capabilities, it is not yet synonymous with complete autonomy. Drivers must remain engaged and ready to take control, underscoring the ongoing evolution of this technology.
