This is exceedingly cool and tantalizing, but I have the reality of the Cali Highway Patrol, which pulled me over re: my driver side mirror delete today. I got off with a warning. That's actually my second warning. If I had a foot long projection I think I'd catch more trouble. I already run tint where I am not supposed to. I need a strictly legal solution here.

I have noticed this about the trunk lids. I like this idea a lot. I recently took apart the rear deck inside the car and I could attempt this, lifting the third backlight a little higher easily. In fact my first effort at a "spoiler" was maybe not altogether off from this idea... see old attached photo. It was just a 2'x4' sheet of 4mm thick coroplast taped down. I could elevate it a little and shape it in the spirit of the 82 TransAm. I could mount it to the lower window and cut it to curve around the the side, yes? Any further thoughts before I act on this idea?
