There's a simple selling point to touch panels that most people here seem to be missing: it decouples the software/firmware from the hardware. Car manufacturers want to be able to change cars after they are sold. This can be in the positive via OTA updates that fix firmware issues or in the negative by providing "subscription" features that provide a passive income beyond the initial sale. Tesla has been paving a path here with its grandiose claims of "full self-driving" and industrial manufacturers like John Deere have been experimenting with bringing smartphone-style DRM and rent-seeking to motor vehicles. Replacing as many "hardcoded" physical controls with flexible and fungible virtual controls is a logical part of the transition. Why bother producing five different physical "editions" if you can just produce one and then downgrade it in four different ways by gimping the firmware or disabling controls in the UI? This way you can also upsell the features later or put them in a subscription model.
