Automotive glass structures having curves and feature lines and methods for forming the same are provided. An example method includes applying localized heat (e.g., via a laser, heating element) to a location of a substantially planar glass structure and bending the glass structure at that location (e.g., along a line of the planar glass structure) to form a feature line in the glass structure. The bending can be formed to have a radius of curvature of between 2 mm and 5 cm. Additional layers of curved or joined glass layers may further be included to form a curved multi-layer glass structure for automotive use.
