They could've noticed that with the GM/Chevy Volt aka. Opel/Vauxhall Ampera already. That thing has lots of identical touch-sensitive buttons with small text labels (no symbols, no colour coding) arranged in a grid.

So finding the correct button blindly is similarly impossible as with a touchscreen. Great to wipe clean, though.
