Buttons Beat Touchscreens In Cars, and Now There’s Data To Prove It

[Swedish car publication Vi Bilagare] tested 11 new cars alongside a 2005 Volvo C70, timing how long it took to perform a list of tasks in each car. These included turning on the seat heater, increasing the cabin temperature, turning on the defroster, adjusting the radio, resetting the trip computer, turning off the screen, and dimming the instruments. The old Volvo was the clear winner. “The four tasks is handled within ten seconds flat, during which the car is driven 306 meters at 110 km/h [1,004 feet at 68 mph],” VB found. Most of the other cars required twice as long, or more, to complete the same tasks. VB says that “one important aspect of this test is that the drivers had time to get to know the cars and their infotainment systems before the test started.” VB lays the blame for the shift from buttons to screens with designers who “want a ‘clean’ interior with minimal switchgear.”

Even with touchscreens, though, we can see in the spread of scores VB gave to different all-touch cars that design matters. You’ll find almost no buttons in a Tesla Model 3, and we called out the lack of buttons in the Subaru Outback in our review, but both performed quite well in VB’s tests. And VW’s use of capacitive touch (versus physical) for the controls on the center stack appears to be exactly the wrong decision in terms of usability, with the ID.3 right at the bottom of the pack in VB’s scores. I’m not surprised that the BMW iX scored well; although it has a touchscreen, you’re not obligated to use it. BMW’s rotary iDrive controller falls naturally to hand, and there are permanent controls arrayed around it under a sliver of wood that both looks and feels interesting. It’s an early implementation of what the company calls shy tech, and it’s a design trend I am very much looking forward to seeing evolve in the future.
