In-Vehicle Information Systems: Weighing Convenience Against Dangerous Driver Distraction
New studies reveal how modern car dashboards and infotainment systems may increase distraction and risk behind the wheel.
Are Modern Vehicle Information Systems Making Drivers Less Safe?
Driver distraction has become a growing concern as manufacturers pack more interactive technology into modern vehicles. In-vehicle information systems (IVIS)—the digital dashboards, touchscreens, and infotainment controls found in many cars today—are designed to offer convenience and customization. But emerging research questions whether these features may actually worsen the problem of distracted driving by demanding more of drivers’ attention just when it should be focused on the road.
The Rise of In-Vehicle Information Systems
Technology in vehicles has advanced rapidly over the last decade. Automotive designers now offer:
- Touchscreen controls for navigation, music, phone, and climate
- Voice-command systems that let drivers issue instructions without taking their hands off the wheel
- Customizable digital instrument clusters that display speed, alerts, and more
- App integration for calls, messages, news, and social media feeds
While these features promise greater convenience, they can also increase the cognitive and visual workload on drivers, making multitasking behind the wheel more tempting—and risky—than ever before.
Understanding Driver Distraction
Distraction behind the wheel occurs when a driver’s attention is diverted away from the primary task of driving. Distraction is typically categorized into four types:
- Visual Distraction: Taking one’s eyes off the road (e.g., looking at a map or phone)
- Manual Distraction: Taking hands off the wheel (e.g., adjusting a dial or touchscreen)
- Cognitive Distraction: Thinking about something other than driving (e.g., composing a voice message)
- Auditory Distraction: Being distracted by sounds or spoken interactions (e.g., voice assistant responses)
IVIS systems often engage drivers in multiple types of distraction at once. For example, using a touchscreen to adjust navigation can involve looking away from the road (visual), reaching out to tap the screen (manual), considering routing choices (cognitive), and sometimes processing auditory prompts.
Research: How Distracting Are In-Car Information Systems?
A landmark study conducted by the AAA Foundation for Traffic Safety and researchers from the University of Utah examined how long drivers diverted their eyes from the road when using the entertainment and navigation systems in several modern vehicles. The findings were striking:
- Completing simple tasks like tuning a radio or dialing a phone number required drivers to take their eyes off the road for an average of over 20 seconds.
- Programming a destination into an in-car navigation system demanded attention for up to 40 seconds—enough time for a vehicle traveling at 25 mph to cover the length of four football fields.
- Voice-command systems did not eliminate distraction; drivers still spent substantial time visually checking for errors or system status.

This level of distraction is critical given that the National Highway Traffic Safety Administration (NHTSA) estimates 3,000+ deaths per year in the United States alone are attributable to distracted driving.
Comparison Table: Distraction Duration for IVIS Tasks
| Task | Average Eyes-Off-Road Time (seconds) |
|---|---|
| Adjusting Audio/Radio | 15–20 |
| Entering GPS Destination | 30–40 |
| Making a Phone Call (Voice or Manual) | 20–25 |
| Texting/Composing Message | 30+ |

Why Are Vehicle Info Systems So Distracting?
Several factors contribute to the high distraction potential of modern infotainment systems:
- Complex Menus: Touchscreens often require multiple taps or swipes to accomplish a single task, increasing cognitive and visual demands.
- Lack of Physical Controls: Tactile feedback, like turning a knob or pressing a button, lets drivers act without taking their eyes off the road. Flat glass panels force drivers to look away to confirm inputs.
- Slower Voice Commands: Speech interfaces can mishear commands or require lengthy clarifications, frustrating users and adding to distraction time.
- High Customizability: Drivers may be tempted to adjust displays, change apps, or customize settings while in motion, further pulling attention from safe driving.
Insights From Real-World and Simulated Studies
Multiple recent studies reinforce the potential dangers posed by elaborate infotainment and information systems:
- Simulators show that texting or reading messages can reduce reaction times by up to 38% and cause drivers to look away from the road for over 4 seconds at a time—already enough to greatly heighten crash risk at typical city or highway speeds.
- Even simple tasks, like changing the music playlist, become highly distracting when they require searching menus or interacting with a visual-manual interface.
- Comparisons of auditory-speech (voice command) vs. visual-manual inputs show that voice interfaces do reduce visual demand but do not eliminate distraction and sometimes increase cognitive workload, especially when the system operates slowly or misunderstanding occurs.
Types of Distraction Measured in Research
- Visual Glances: Duration and frequency with which the driver looks away from the roadway
- Manual Interactions: How often and how long a hand is off the wheel while interacting with controls
- Subjective Workload: How mentally demanding drivers rate different tasks and inputs
- Driving Performance: Measures like lane-keeping, reaction to hazards, and following distance
What Can Be Done to Minimize Distraction?
Automakers and safety advocates are seeking ways to balance digital convenience with the need for undivided driver attention. Strategies include:
- Improving voice-recognition systems to be faster, more accurate, and capable of handling natural language.
- Streamlining interfaces to require fewer steps and offer larger, more legible buttons for the most essential functions.
- Restricting certain features (e.g., text entry or complex tasks) while the vehicle is in motion.
- Heads-up and augmented reality displays that project information directly in the driver’s line of sight so attention stays closer to the road.
- Developing distraction detection algorithms that monitor driver attention with cameras, sensors, and real-time feedback alerts when focus lapses are detected.
Consumer education also plays a key role, as even advanced systems cannot prevent every form of driver-induced distraction. Understanding the risks associated with in-car technology is crucial for safer adoption and use.
The Complex Tradeoff: Convenience vs. Safety
Although in-car systems are designed to assist drivers, the convenience they offer often comes at the cost of split attention. The challenge lies in creating vehicle systems that:
- Enable safe access to navigation, communication, and entertainment
- Minimize visual, manual, and cognitive demands
- Discourage non-critical tasks while driving
- Carry effective prompts or countermeasures to get inattentive drivers back on task
Regulatory standards, such as those set by NHTSA, are being developed to assess the distraction potential of new in-vehicle technologies before widespread release. But continued innovation and real-world monitoring are needed to ensure these systems help, rather than hinder, safe driving.
Tips to Reduce Distracted Driving With Modern IVIS
- Set up your GPS, playlists, and climate controls before starting to drive.
- Rely on voice commands where possible, but practice using the system while parked to minimize on-road confusion or errors.
- Avoid engaging with complicated apps, reading messages, or making manual adjustments while your vehicle is moving.
- Keep your focus on driving during complex or high-traffic road situations—even if your system offers hands-free features.
- Educate passengers about the risks and ask for assistance if navigation or communication is necessary mid-drive.
Frequently Asked Questions (FAQs)
How do in-vehicle information systems compare to traditional car controls in terms of distraction?
IVIS typically require more visual attention and more steps to operate, compared to analog dials and knobs. With touchscreens and complex menus, drivers must look away from the road more often and for longer periods, increasing crash risk.
Are voice-activated systems safer?
Voice-activated controls do lower visual-manual distraction but may increase cognitive workload if they are slow, make mistakes, or require clarifications. They improve safety over touch-based controls, but only if well-designed and responsive.
What features in an infotainment system are most likely to distract drivers?
Navigation programming, texting, searching through music or app menus, and any task requiring more than a single touch or command are especially distracting. Systems that require multi-step processes or offer notifications can also increase distraction.
Is there a difference in distraction risk for older vs. younger drivers?
Research indicates that younger drivers may acclimate faster to new technology but may also be more prone to risky multitasking behaviors. Older drivers can be more affected by unfamiliar or complex interfaces, resulting in longer distraction times.
How can technology help reduce distraction, rather than cause it?
Real-time monitoring systems using cameras and sensors can detect when drivers are distracted and issue warnings. Interface design improvements, limitation of functions while driving, and intelligent voice recognition can all help minimize unnecessary distractions.
Conclusion: Navigating the Digital Road Ahead
Car technology has the power to enhance mobility, comfort, and engagement. But as vehicles become rolling digital hubs, it is crucial to keep focus and safety as the highest priorities. Both consumers and manufacturers have roles to play in shaping a safer driving future—where technology serves the driver, not the other way around.
