1. An electrically heatable glazing panel comprising:
a substrate; and
a first electrically heatable zone comprising:
i) a transparent, electrically conductive coating layer,
ii) first and second spaced bus bars adapted to supply electrical voltage across the transparent, electrically conductive coating layer, and
iii) a conductive pathway defined between the first and the second spaced bus bars;
wherein the conductive pathway is provided by a pattern of coated and decoated regions in the transparent, electrically conductive coating layer of the first electrically heatable zone to affect electrical resistivity of the transparent, electrically conductive coating layer in the first electrically heatable zone, and
wherein the first electrically heatable zone is delimited by a windshield wiper rest area.
