An automotive windshield assembly comprising: - a curved windshield; - windshield wipers for wiping the windshield and being positioned in a park position when not activated; and - a windshield wiper park position heater, comprising: a flexible polymeric insulator sheet conforming to a lower surface of the curved automotive windshield, having a length aligned with a length of the windshield wiper in park position and sized so that a periphery of the insulator sheet proximately circumscribes a contact area of a windshield wiper blade against a windshield in the park position, the insulator sheet supporting: (a) a resistive layer generating heat with the passage of electricity therethrough; and (b) a conductive electrode communicating with the resistive layer to pass current therethrough; said resistive layer and electrode extending along an entire length of the insulator sheet proximate to a contact area of the windshield wiper blade against the windshield in park position when the insulator sheet is applied to the automotive windshield, characterized in that the electrode includes upper and lower electrodes extending along a length of the insulator sheet at opposite edges of the insulator sheet across its width and including a feeder electrode extending from one end of the insulator sheet to a connection point with one of the upper and lower electrodes at a midpoint along a length of the flexible polymeric insulator sheet; and wherein the upper and lower electrodes each include finger elements extending outwardly in interdigitated arrangement with finger electrodes of another of the upper and lower electrodes. - a curved windshield;
