Uniform heating.
I think acceptable quality can be achieved. Couln't be worse than those mid/late-1950s compound curve windshields made the way aerohead describes.
I've been looking, today, at the new Lexus RZ540e. It has an interesting design vocabulary.

That's an interesting use of a perforated mesh over two different air intakes, one vertical and one horizontal. This has the deepest pores I've seen since the Porsche 959:
What comes across on the production version is the strong taper of the front fender top and bottom, while the rear fender is bulging out at the middle. Look at the rear edge of the door cut line, and the strong chamfer on the nose. The concept has a blunt, narrow nose that stands proud of the windshield, with massive rectangular intakes.
