Why Your Car's Touchscreen Is More Dangerous Than Your Phone (carsandhorsepower.com)

(Saturday June 21, 2025 @09:34PM (EditorDavid) from the held-on-wheels dept.)


"Modern vehicles have quietly become rolling monuments to terrible user experience, trading intuitive physical controls for flashy but dangerous touchscreen interfaces," [1]argues the site Cars & Horsepower , decrying "an industry-wide plague of poorly designed digital dashboards that demand more attention from drivers than the road itself."

> The consequences are measurable and severe: studies now show touchscreen vehicles require up to four times longer to perform basic functions than their button-equipped counterparts, creating a distracted driving crisis that automakers refuse to acknowledge. A Swedish car magazine, Vi Bilägare , [2]conducted a study [in 2022] comparing how long it takes drivers to perform basic tasks like adjusting climate controls or changing the radio station using touchscreens versus traditional physical buttons. The results showed that in the worst-performing modern car, it took drivers up to four times longer to complete these tasks compared to an older vehicle with physical controls... Even after allowing drivers time to familiarize themselves with each system, touchscreen-equipped cars consistently required more time and attention, which could translate into increased distraction and reduced safety on the road....

>

> A seminal 2019 study from the University of Utah found drivers using touchscreens exhibited:

>

> - 30% longer reaction times to road hazards

> - Significantly higher cognitive workload (as measured by pupil dilation)

> - More frequent and longer glances away from the road

>

> The reason lies in proprioception — our body's ability to sense its position in space. Physical controls allow for muscle memory development; drivers can locate and manipulate buttons without looking. Touchscreens destroy this capability, forcing visual confirmation for every interaction. Even haptic feedback (those little vibrations mimicking physical buttons) fails to solve the problem, as demonstrated by a 2022 AAA study showing haptic systems offered no safety improvement over standard touchscreens...

>

> [3]A study from Drexel University introduced a system called [Distract-R](), which uses cognitive modeling to simulate how drivers interact with in-vehicle interfaces. It found that multi-step touchscreen tasks increase cognitive load, diverting attention from the road more than physical buttons.... Furthermore, a [4]systematic review on driver distraction in the context of Advanced Driver Assistance Systems (ADAS) and Automated Driving Systems (ADS) highlights that even with automation, drivers remain vulnerable to distraction, especially when interacting with complex interfaces...

There's also software reliability issues (even before the issue of "feature paywalls"). But some manufacturers are going back, according to the article. "After receiving widespread criticism, Porsche added physical climate controls back to the Taycan's center console. Nissan's latest concepts feature prominent physical buttons for common functions..." And Mazda eliminated touch capability entirely while moving, "forcing use of a physical control knob... The system reduces glance time by 15% compared to touch interfaces while maintaining all modern infotainment functionality."

The article recommends consumers prioritize physical controls when vehicle shopping, seeking out models with buttons. But there's also "aftermarket solutions," with companies like Analog Automotive "developing physical control panels that interface with popular infotainment systems, bringing back tactile operation." Another option: voice commands (like on GM's latest systems).

"Ultimately, the solution requires consumer pushback against dangerous interface trends.... The road deserves our full attention, not divided focus between driving and debugging a poorly designed tablet on wheels."

How hard would it be to put some kind of plastic overlay with holes cut into it where the different touch screen buttons are programmed to appear? Make the holes shaped like the function the virtual button behind it performs, kind of like the raised arrows and such on old school cassette deck buttons so people could find the button they want by feel as well as by looking. The plastic overlay on a touch screen can't really have raised indicators and retain the function, I'm thinking the holes being cut wou

Every time you start a Honda you get one of these stupid screens:

But Honda's ICUs are so slow to start that you're often a long way down the road before this screen even appears, and then you have to take your eyes off the road to press the OK button before car's systems become fully usable!

It is like the joke about Braille keys on a drive up ATM. It's part not wanting to get sued and part not wanting to vary the user interface to better match the application.

What I find annoying is the inability to adjust the navigation while driving. It's not that I'm doing this while driving, it's that the passenger is also locked out. I don't run into this much myself as my vehicle doesn't have a built-in navigation, I use my iPhone for that and it serves me very well. It's when I'm a passenger or driv

My 2019 Camry hit it nearly perfectly. Touch screen is for entertainment only, and big presets are right there, easily configured. All controls including climate are physical. My only complaint is that CarPlay isn't wireless. Well... I have other complaints, but they are nitpicks...

I've even got it set up so I can arm/disarm my home security with Siri voice commands, and the button to engage voice control is on the steering wheel. And the garage door is controlled from the mirror.

I agree with the premise here. Touchscreens are inherently a safety problem. Especially if what you want is nested. I really hate this direction. A car is not a smartphone, and shoving everything into incorrect interfaces sucks donkey balls.

Put stereo controls on the steering wheel, even cheap cars often offer this as an option now anyway. Put physical climate controls below the screen. You might need to look to grab the knob, but you can look at the road while you turn it. With some of these screen-only climate control systems they have sliders or other stupid controls that require a lot of attention. And also a button to activate the camera since every vehicle has poor rear visibility now.

2017 GLE 350, there is a control dial that rotates through things on the screen and physical controls for everything else. The screen itself isn't a touch screen. The wheel control is easy to use and there are no fingerprints all over a screen. It even works great with CarPlay.

The new ones have a trackpad instead of the wheel, mine actually has both but I have the trackpad disabled because it's in a somewhat awkward place. The new ones put it where the wheel is on mine so that isn't as much of an issue.
