@paco I think you make a very good point, particularly when navigating functions in situations where attention to one task is critical and all other functions have to be designed to be completed while minimally diverting attention. Touchscreens make it easy for designers, manufacturers and engineers (and make updates easier) at the expense of the user's cognitive load. Especially in cars, this is the wrong choice. Nothing that a user may need to change while driving should be on a touch screen
