1. A vehicle interior system, comprising:
a base comprising a curved surface;
a display disposed on the curved surface; and
a cover glass disposed on the display, the cover glass comprising:
a first region comprising a first major surface, a second major surface opposite the first major surface, and a first thickness defined as a distance between the first major surface and the second major surface; and
a second region comprising the first major surface, a third major surface opposite the first major surface, and a second thickness defined as a distance between the first major surface and the third major surface; and
wherein the display is attached to the third major surface, the second region corresponding to a touch-sensitive region of the display,
wherein the second thickness is greater than the first thickness,
wherein the cover glass is curved in at least the first region,
wherein the first region comprises a reverse curve in which radii of curvature in different directions meet at an inflection line, the inflection line delineating a boundary between concave and convex curves of the first major surface where a curvature of the first major surface changes sign.
