Tesla Renames Driver Assistance Features in California to Comply With State Law | Taha Abbasi

Tesla has shipped an update that renames several of its driver assistance features in California, complying with state regulations that prohibit automakers from using names that could mislead consumers about a vehicle’s autonomous capabilities. Taha Abbasi digs into what changed, why California forced the issue, and what this means for the national conversation about how we talk about self-driving technology.

What Tesla Renamed and Why

The update, which applies to Tesla vehicles registered in California, changes the displayed names of certain driver assistance features within the vehicle’s interface. According to Tesla’s release notes, the changes only update feature names and descriptive text; no underlying functionality has been modified. Your car drives exactly the same way it did before the update. The buttons just say something different.

California’s SB 1398, signed into law in 2024 and taking effect in phases, specifically targets automakers who use terms like “Autopilot,” “Full Self-Driving,” or “autonomous” in marketing or in-vehicle displays for systems that require driver supervision. The law reflects growing concern among regulators that consumers may overestimate the capabilities of driver assistance systems based on their names alone.

The specific name changes in Tesla’s update have not been fully detailed in the release notes, which simply state that the update changes feature names and text. However, industry observers note that Tesla has been gradually adjusting its terminology, including adding more prominent disclaimers about the supervised nature of its driving assistance features.

The Naming Problem in Autonomous Driving

The debate over what to call driver assistance features has been simmering for years. Critics have long argued that names like “Autopilot” and “Full Self-Driving” create a dangerous expectation gap. A customer who pays for “Full Self-Driving” might reasonably expect the car to drive itself fully, without supervision. The reality, as Tesla’s own documentation makes clear, is that these features require the driver to remain attentive and ready to take control at all times.

Tesla is not the only automaker facing this issue. General Motors’ “Super Cruise” and Ford’s “BlueCruise” have also been scrutinized for names that may overstate capabilities. BMW’s “Highway Assistant” and Mercedes’ “Drive Pilot” have drawn similar attention. The industry as a whole has a naming convention problem that regulators are now stepping in to address.

Taha Abbasi takes a nuanced view of the naming controversy. “Tesla’s FSD technology is genuinely impressive and getting better with every update,” Abbasi notes. “But the name has always been aspirational rather than descriptive. When you call something ‘Full Self-Driving’ and then require the driver to supervise it at all times, you are creating cognitive dissonance. California is right to push for clearer communication, even if the underlying technology is excellent.”

California’s Regulatory Leadership

California has consistently been at the forefront of autonomous vehicle regulation. The state was among the first to establish a framework for testing autonomous vehicles on public roads, and it now hosts the largest concentration of autonomous vehicle testing and commercial operations in the country. Waymo, Zoox, Cruise, and numerous other companies operate under California’s regulatory framework.

SB 1398 represents a new dimension of regulatory involvement: governing not how autonomous vehicles operate, but how they are marketed and described to consumers. The law recognizes that consumer behavior is influenced by marketing language, and that misleading names can contribute to dangerous misuse of driver assistance features.

Other states are watching California’s approach closely. If the naming regulations prove effective at reducing consumer confusion without stifling innovation, other states may adopt similar laws. The alternative is a patchwork of state regulations that forces automakers to maintain different naming conventions for different markets, which is exactly what Tesla is now doing with its California-specific update.

The Industry Response

The automotive industry’s response to California’s naming regulations has been mixed. Some automakers have proactively adjusted their marketing to avoid regulatory conflicts. Mercedes, for example, has been careful to distinguish between its Level 2 driver assistance systems and its Level 3 “Drive Pilot” system, which is certified for hands-free driving under specific conditions in certain markets.

Tesla’s approach has been to comply with the letter of the law while maintaining its overall FSD branding and pricing strategy. The California-specific name changes affect only the in-vehicle display text, not the broader marketing, pricing, or subscription model for Full Self-Driving. This allows Tesla to comply with state law while preserving the brand identity that has been central to its autonomous driving narrative.

Taha Abbasi sees the industry response as a preview of broader regulatory trends. “California is often the testing ground for regulations that eventually go national,” Abbasi explains. “Automakers who adapt to California’s naming requirements now are positioning themselves for what will likely become a nationwide standard. The smart approach is to get ahead of the regulation rather than fight it.”

Consumer Impact: Does It Matter?

The practical impact on Tesla owners in California depends largely on how they use and perceive the driver assistance features. For experienced Tesla owners who already understand the limitations of FSD and treat it as a supervised driving assistant, the name change is cosmetic. They know what the system can and cannot do, and a different label on the screen does not change their behavior.

For new Tesla owners or prospective buyers, however, clearer naming could meaningfully improve safety. If a first-time Tesla owner sees a feature labeled in a way that clearly communicates “this helps you drive but you must still drive,” they are less likely to disengage from the driving task. Every accident that is prevented by clearer communication represents a life saved, and that outcome is worth the naming adjustment.

Research on human-machine interfaces consistently shows that the names and labels used for automated systems influence user behavior. Systems described as “automatic” receive less human oversight than systems described as “assistive,” even when the underlying capabilities are identical. This finding supports the regulatory rationale for requiring names that accurately describe a system’s level of autonomy.

The Broader Conversation About Autonomy Levels

The naming controversy is really a proxy for a deeper conversation about the SAE (Society of Automotive Engineers) autonomy levels and how they should be communicated to consumers. The current system defines six levels (0-5) of driving automation, from no automation to full automation. Most driver assistance systems on the market today, including Tesla’s FSD, operate at Level 2, which requires the driver to remain engaged at all times.

The gap between Level 2 (driver must supervise) and Level 3 (system handles driving in specific conditions, driver is fallback) is enormous in terms of both technology and legal liability. Yet the marketing language used by automakers often blurs this distinction, leading consumers to believe that their Level 2 system is closer to Level 3 or 4 than it actually is.

What This Means for FSD’s Future

The California naming requirement does not change Tesla’s technology development roadmap. FSD will continue to improve through over-the-air updates, the robotaxi service in Austin will continue to expand, and Tesla’s long-term vision of fully autonomous vehicles remains unchanged. What changes is the regulatory environment in which that vision is being pursued.

Taha Abbasi concludes with a forward-looking perspective. “The best outcome of California’s naming law is that it forces the industry to be honest about where the technology actually is today, while continuing to invest in where it needs to be tomorrow,” Abbasi states. “Tesla’s FSD is remarkable technology that is getting closer to true autonomy with every update. Calling it what it actually is today does not diminish what it will become. If anything, honesty about the current state builds more trust in the future promise.”

For the autonomous driving industry, the California naming regulations represent a maturation of the regulatory framework. Early regulations focused on safety testing and operational permits. Now regulations are addressing consumer communication and expectations. This evolution is necessary as autonomous driving technology moves from research labs and pilot programs into mainstream consumer vehicles that millions of people will interact with daily.
