[Land-speed] roof flaps

[Elon]

Benn I have been interested in the same thing. I measured the angle on a
NASCAR car on display. It was 45 degrees to the longitudinal line of the
car.  -Elon

Anyone have a sense of how tricky the design of roof flaps is?  Snip. I
assume they must be positioned exactly right on theroofline to both stay
shut during forward motion and open readily as the yaw angle gets to the
critical point.  Thoughts?
