Modern cars hide critical functions behind touchscreens. Research consistently shows this increases distraction, reaction time, and accident risk.
Physical buttons allow drivers to act by muscle memory — without visual confirmation. Below are independent studies, expert opinions, and regulatory responses that explain why this matters.
Ctrl-Bar safety analysis & multiple human-machine interface studies
Studies show physical buttons reduce cognitive load and interaction time. Drivers can adjust controls without looking away from traffic, relying on tactile feedback instead of visual search.

Brain researchers explain that the human brain cannot safely split attention between driving and touchscreen interaction. Even short interactions cause delayed reaction times comparable to alcohol impairment.

Test drivers completed common tasks significantly faster using physical buttons than touchscreens. Touchscreen use resulted in longer eyes-off-road time and poorer lane control.

Euro NCAP now encourages physical controls for critical vehicle functions. Cars relying solely on touchscreens may lose safety points — a clear signal that tactile interfaces are safer.
