I know that I successfully used hybrid button-touchscreen interface for my Prius for over a decade. It was great and resulted in no accidents or even distractions.

It's modular so additional features can be integrated by pure software so upgrades are possible.

Sure 90% touchscreen (some stuff is still manual) sounds crazy but Model3 owners don't seem to complain too much. I'd bet an 80% interface would work great today.

Enter a perfected voice control and L4 auto drive and we'll officially be living in the future.
