It’s Time for a Driver Distraction Rating

May 26, 2026

For decades, automobile safety has been measured through crash survivability. We rate vehicles based on airbags, crumple zones, rollover resistance, braking distance, and collision-avoidance systems. Yet as modern cars evolve into increasingly software-driven environments, one critical safety question remains largely absent from public discussion:

How distracting is the vehicle itself?

According to the National Highway Traffic Safety Administration, driver distraction guidelines recommend limiting the duration and complexity of in-vehicle interactions in order to reduce the amount of time drivers spend looking away from the road. Yet modern vehicles increasingly centralize critical functions inside touchscreen interfaces that often require multiple visual interactions to complete even simple tasks.

Today’s drivers routinely interact with touchscreen dashboards, nested menus, driver-assist systems, smartphone integrations, voice interfaces, and constantly changing software controls while traveling at freeway speeds. In many modern vehicles, even basic tasks such as adjusting climate controls, modifying driver-assist settings, or troubleshooting dashboard displays now require significantly more visual and cognitive attention than older tactile systems demanded.

Despite this growing cognitive burden, consumers have no standardized way to evaluate how much attention a vehicle demands from its driver.

I began thinking more seriously about this after driving a late-model rental car equipped with a large touchscreen interface and semi-autonomous driver-assist features. More than once, I found myself attempting to troubleshoot relatively minor interface problems while driving on the freeway. The vehicle’s windshield projection system would sometimes appear and sometimes not. I assumed I had accidentally dimmed a dashboard setting or disabled something unintentionally, so I repeatedly found myself navigating menus and searching for controls while the vehicle remained in motion.

What disturbed me afterward was not simply the distraction itself, but how easily the car’s driver-assist systems created a false sense of security that encouraged continued interaction with the interface. Because the vehicle appeared to be competently handling portions of the driving task, it became psychologically easier to justify “just one more glance” at the screen.

I also noticed something else that felt deeply familiar: The crash of United Airlines Flight 173

Years ago, I watched a documentary about United Airlines Flight 173, an aviation disaster caused not by catastrophic mechanical failure, but by cognitive fixation. The flight crew became so focused on troubleshooting a landing gear indicator problem that they gradually lost awareness of the larger operational situation around them. The aircraft eventually ran out of fuel and crashed.

The issue was not the landing gear itself. It was the crew’s loss of situational awareness.

Aviation human-factors researchers have spent decades studying how automation, workload, and attentional fixation affect operator performance. Pilots are specifically trained to recognize forms of task saturation and loss of situational awareness because even highly trained professionals can become cognitively trapped by relatively minor technical problems while losing awareness of the broader operational environment.

Modern vehicles may not require pilot-level training, but they are increasingly introducing similar human-machine interaction challenges to ordinary drivers.

For example, I discovered that the car manufacturer of my rental no longer provided a physical owner’s manual. Had I owned the vehicle, accessing free digital owner’s manual would have required downloading an app, creating an account, entering the vehicle’s 17-digit VIN, and navigating a digital ecosystem just to understand basic vehicle functions. Since it was a rental, I relied on Google’s Gemini to answer basic car-related questions.

Instead of minimizing distraction, this approach seemed to pull the driver further into another screen-based environment — on a smartphone.

Distracted Driving Is Nothing New

Drivers have always eaten, smoked, tuned radios, unfolded paper maps, argued with passengers, and looked away from the road.

Historically, automobiles evolved around a relatively standardized interaction model. Drivers could move from one vehicle to another and still understand the basic operational language of the machine. Climate controls, radios, dashboard dimmers, and windshield wipers relied heavily on tactile feedback, spatial consistency, and muscle memory. A driver could often adjust a control by feel alone without taking their eyes off the road.

Modern software-driven vehicles increasingly replace that tactile consistency with flat glass surfaces, dynamic menus, hidden settings, contextual controls, and interfaces that behave more like smartphones than automobiles.

This shift creates a dangerous contradiction

Automakers are simultaneously introducing increasingly sophisticated driver-assist systems while also creating environments that encourage greater interaction with complex software interfaces. In some cases, the vehicle itself becomes the distraction.

In 2018, Nielsen Norman Group published an article arguing that UX professionals should consider distracted driving as part of the broader ethical responsibility of interface design. The article emphasized that poor signifiers, excessive cognitive load, and unnecessarily complex interactions can become safety concerns when users operate systems under real-world distraction and stress conditions.

Ironically, many of these systems are marketed as “intuitive.” Yet operating them may require account creation, app downloads, menu exploration, software updates, voice-command memorization, and repeated visual interaction. This is particularly problematic in rental cars or unfamiliar vehicles, where drivers lack established muscle memory and system familiarity.

This concern is no longer limited to UX critics or automotive traditionalists. The European New Car Assessment Programme has begun signaling that certain core vehicle functions should remain accessible through physical controls in order to support safer operation and reduce distraction-related cognitive demand.

To their credit, some automakers appear increasingly aware of these concerns. Volvo Cars has publicly framed portions of its evolving UX strategy around reducing cognitive burden, simplifying interaction, and integrating safety more directly into the vehicle’s digital experience. The company’s long-standing emphasis on human-centered safety has expanded beyond crash survivability into questions involving driver attention, distraction, and behavioral interaction with increasingly software-driven systems.

At the same time, even Volvo illustrates the broader tension facing the industry. Many newer vehicles continue moving toward large centralized touchscreens and increasingly software-mediated controls, reflecting the competing pressures of minimalism, technological branding, software integration, and operational usability.

Increasingly, industries seem to confuse engagement with effectiveness

That distinction matters profoundly in operational environments. A social media platform may benefit from maximizing user interaction. A vehicle traveling at 70 miles per hour should not.

Cars are not smartphones. They are high-speed operational systems functioning in unpredictable environments under conditions of stress, fatigue, divided attention, weather variability, and cognitive overload. Human beings are not infinitely multitasking creatures, even if modern software increasingly assumes otherwise.

The solution is not necessarily banning technology. Many modern safety systems genuinely reduce accidents and save lives. Advanced driver assistance, blind-spot monitoring, collision avoidance, and lane-keeping technologies all provide meaningful benefits.

But perhaps it is time to acknowledge that interface complexity itself carries safety implications.

Just as we rate vehicles for crashworthiness and fuel economy, perhaps we should begin evaluating them for distraction burden:

How many seconds does it take to perform common tasks?
How often must drivers look away from the road?
Which functions require touchscreen interaction?
Which controls remain tactile?
How cognitively demanding is the interface under real driving conditions?
How easily can drivers recover from confusion or incorrect inputs?

In other words:

How much attention does the vehicle demand from the human being operating it?

As vehicles continue evolving toward increasingly software-defined and semi-autonomous systems, this question may become just as important as horsepower, braking distance, or crash-test ratings.

Because the next major automotive safety challenge may not simply involve protecting people during collisions.

It may involve protecting human attention before collisions happen.
