<p>Note that the ATS, like many other cars, has an optional touch screen interface for controls like the radio, HVAC, etc. (called CUE for Cadillacs). Before buying the car, or deciding whether to get one with the touch screen, see if you like the idea of using a touch screen while driving. Many do not, since it does not allow for operating the controls by feel. If you do find a touch screen acceptable, consider how large the virtual buttons are (too small and it is too easy to use the wrong control, especially while driving) and whether you have to go through layers of menus to get to something you use frequently.</p>
<p>Another control annoyance is the use of touch-buttons instead of regular press-buttons for controls, since touch-buttons also cannot be operated by feel without activating other touch-buttons.</p>
