[The Atomic Ass]

I've seen a few of the threads about basjoos Aerocivic, and it's gotten me to thinking about my design a little. I was originally planning to get as close to a tear drop as possible, by placing the windshield out far ahead of the cabin, but I'm wondering if the effort would be worth it, or if I could even achieve .11. I'd probably end up at more like .14 or .15, given the wheels and imperfect tear drop shape, I'm thinking.

This is on a ground-up build, so I can really do it either way, but I'm thinking the necessary glass may be very costly and/or heavy.
