I came up with another pipedream project.
This is another one that I doubt I'll have the courage to do but I want to ask what you think. Inspired by the fact that my car has a fairly steep windshield. Current Japanese high-FE products have a nearly continuous straight line from front of hood to top of windshield, except for a sort of cowling in front of the wiper blades.
(This is not my car, but the front body lines are the same. Mine = wagon)

I'd build it out of Lexan or whatever is the clearest, most scratch resistant plastic I can work with. This first version would need some clever hinging for when you want to check the oil. Which is why I thought of the second version...

This is a more moderate version.
Trebuchet03 and basjoos and others, what do you think about the aero value of these?
I think the second version would still need to be clear, but it can be attached solidly to the hood so the hood will still open. Hood is spring loaded but I could add a prop rod if needed for the weight of the mod.
