Open the door of a new luxury car and you’ll probably be greeted by a screen the size of a small television. Mercedes-Benz’s 2021 S-Class was a high-profile example of the trend, with a tall, tablet-style display dominating the center stack. Automakers love car touchscreens. Drivers have mixed feelings. Let’s weigh the arguments over car touchscreens properly instead of picking a side by reflex.
How we got here
Car dashboards used to be a wall of buttons, knobs and dials. Each function had a physical control: one for volume, one for temperature, one for the fan. Over time, as features multiplied, so did the buttons. Navigation, media, driver assistance and connectivity piled in, and the dashboard became crowded.
Car touchscreens offered a tidy solution. One surface could host any number of functions, updated through software. Smartphones had trained everyone to expect touch interfaces, so carmakers followed. Tesla pushed the idea hard, and others adopted it, making bigger and bigger displays a mark of a modern vehicle.
The case for car touchscreens
- Flexibility. Software can add features or fix problems through updates after you buy the car.
- Clean design. Fewer physical controls give a minimalist look that many buyers like.
- Better maps. A large display makes navigation easier to read at a glance.
- Manufacturing savings. Fewer parts and simpler wiring reduce costs, which is a quiet but real motivation.
- Showroom appeal. A bright screen looks impressive and signals technology.
The case against car touchscreens
The main complaint is that touchscreens demand visual attention. A physical knob can be found by feel, so your eyes stay on the road. A touch target requires you to look, aim and confirm. Even a brief glance away at highway speed covers a lot of distance.
Adjusting something simple like air conditioning can turn into a menu trek. Glare, fingerprints and lag add frustration. Gloves can interfere with touch input. Bumpy roads make accurate tapping harder.
Independent safety researchers in several countries have compared tasks done with physical controls and with touchscreens. In general, the findings point toward physical controls being faster and less distracting for frequently used functions. Some safety rating programs have said they will take physical controls into account in their assessments, which pushes manufacturers to reconsider.
Why the habit of touching a screen matters
One reason car touchscreens feel natural is that people already carry a touchscreen everywhere. The change in habit began with phones, a story told in our short history of how smartphones reached billions. But a phone is held close and used while stationary. A dashboard display sits at arm’s length, moves with the car and is used while your attention should be on traffic. That difference is the heart of the argument against relying only on car touchscreens.
What good design looks like for car touchscreens
It isn’t all or nothing. The best systems blend approaches:
- Keep essential controls physical. Volume, hazard lights, defrost and climate basics benefit from tactile buttons or dials.
- Make the screen responsive. Quick reaction and clear visual feedback reduce frustration.
- Use voice well. Good voice recognition handles tasks like navigation and calls without taking hands from the wheel, though it has to actually work.
- Place the display sensibly. Higher positions reduce the time your eyes spend off the road, while reflections and sun glare need handling.
- Offer haptic feedback. A small vibration or click confirms a press without looking.
Software upkeep matters for car touchscreens
A car lasts a decade or more; a screen’s software may feel dated in half that time. Buyers should ask how long the manufacturer will provide updates, how smartphone mirroring works and whether the system can be repaired or replaced affordably. A cracked screen can be an expensive repair, since it often controls many features.
Repair and long-term ownership
Think about the car in year eight, not just on the showroom floor. Car touchscreens often handle climate, camera views and settings, so a failure can disable more than the radio. Ask what a replacement costs, whether independent shops can fix it and how long software updates will continue. The technology behind these panels is explained in general terms in the Wikipedia article on touchscreens.
It is also fair to ask who pays when design fashions change. If a maker later restores physical buttons, owners of earlier car touchscreens cannot add them. Reading owner forums and long-term reviews for the exact model gives a more honest picture than a launch-day demo, and it is worth doing before you sign.
Buying tips
- Test-drive with the screen in real use: change the temperature, switch audio sources, start navigation, all while the car is moving (with a passenger doing it, or after parking).
- Check which functions still have physical controls.
- Try the voice commands.
- Look at the screen in bright light.
- Ask about update policies and warranty coverage for the display.
Where it’s heading
Some automakers have already started bringing back buttons after customer feedback, a rare case of the market correcting a design fad. Others are experimenting with head-up displays, which project information onto the windshield, and with improved voice assistants, which may reduce the need to touch anything.
Big screens are not going away, but the pure screen-only dashboard looks like a phase. The long-term winner is likely the thoughtful hybrid: a large display for the things that benefit from it, and real knobs for the things you do without thinking. Drivers, after all, want a car they can control without taking their eyes off the road.
