Are Big Car Infotainment Screens Dangerous? – Ideal Size & Distraction Risks

Remember when a 10-inch touchscreen in a car felt like a luxury? Now, some models boast digital panels stretching across the entire dashboard, rivaling a home television in size. But as automakers race to offer the biggest and brightest, a crucial question arises: what is the ideal size for an in-car display? The answer, it turns out, is surprisingly nuanced.

The Allure of the Mega-Screen

Large displays have become a defining characteristic of modern vehicles, instantly signaling technological advancement and a premium experience. The recently launched Mazda CX-6e exemplifies this trend, featuring an expansive, roughly 26-inch panel dominating its interior. This creates a “digital cockpit” aesthetic, where software increasingly replaces traditional controls, transforming the cabin into a tech-focused space.

On paper, the logic is sound. A larger surface area allows for sharper graphics, the ability to split the screen for multiple functions, and greater personalization options. From a marketing perspective, bigger undeniably *looks* more impressive and modern. However, a car isn’t a showroom, and drivers aren’t passive consumers.

The Distraction Factor: A Growing Concern

Every glance at a screen is a moment diverted from the road. Each additional step through a menu increases mental workload and, crucially, driver distraction. The relationship between screen size and actual benefit isn’t linear. Studies by the European Transport Safety Council (ETSC) consistently highlight infotainment systems as a major source of driver distraction, contributing to increased accident risk. A 2023 report indicated that interacting with in-car infotainment systems increases the risk of a crash by a factor of two.

The Sweet Spot: Finding the Ideal Size

Research into driver behavior reveals a critical insight: screens that are too small suffer from poor readability, while those that are too large encourage longer and more frequent interactions. Independent studies tracking glance time away from the road and cognitive load suggest an optimal range for display placement. Generally, screens exceeding 14-15 inches require drivers to divert their attention for longer periods during common tasks.

In other words, a massive display might be visually impressive, but it simultaneously demands more attention than is safe while driving. The large surface area tempts designers to pack in more features, resulting in a clean aesthetic but also necessitating a hunt for basic controls within nested menus.

Studies show that glance times increase noticeably with screens larger than approximately 14-15 inches. This translates directly to increased risk, particularly during routine maneuvers.

A Return to Reason: Audi Leads the Charge

Some established automakers are beginning to push back against the relentless pursuit of larger screens. Audi has openly criticized the trend, acknowledging that the race for maximum screen size wasn’t always a step in the right direction. Massimo Frascella, Audi’s Head of Design, recently stated, “Large screens aren’t the best user experience. It’s technology for technology’s sake. For us, technology should be visible when you need it, and disappear when you don’t.”

New Audi concepts are showcasing smaller, around 10-inch central displays, more elegantly integrated into the dashboard and complemented by physical controls for essential functions. This shift represents a welcome refocus on human-centered design.

The Future of In-Car Displays: A Balanced Approach

A consensus is emerging: a sensible infotainment system strikes a balance – a screen large enough for quick and clear information display, yet compact enough to avoid overwhelming the interior and tempting drivers to browse during operation. This ideal is often enhanced by a high-quality head-up display and readily accessible physical controls.

The Mazda CX-6e demonstrates the extremes of current design. However, the future of infotainment likely won’t belong to excessively large screens. Instead, we’ll see a focus on finding the optimal size and a partial return to tactile controls.

Did you know? The average driver spends approximately 2.5 seconds per 60 mph traveling one mile. Even a brief glance at a screen can cover a significant distance without driver awareness.
