Good. Touch screen controls are a good tool for communicating visual information while having some way to still give users some controls. Tactile controls are good tools for when the operator needs to visually focus on something else and feedback can be sensed in other ways. For cars, the only visual information it should show to the driver are either things that are controlled outside of a touch screen (speedometer, tach) or can't be controlled while the vehicle is in operation anyway (oil temp gauge, etc). Everything else can be intuitively sensed by the driver's other senses and the important part of the control is the feedback saying that you are in fact manipulating the controls properly.
