Because if they were; there would be some excitement and talk about this simple mod.

Correctly sized inlet and outlet plus waste heat gets you the Meredith Effect.

ie: Get the flow going backward, with the right sized opening/velocity
And you get the same drag decrease without losing cooling capacity.

I always wonder how often my links are followed?
I get the feeling not at all!?

Especially as it's a car company's research.

Ah! Some 'free standing' pics found!

Credit where it's due, that looks like it would work pretty well. Admittedly, I have no idea what the underside of the Insight looks like, I've been mainly behind the wheel of it.

Thx!
The link to the paper again, with yet more pics!

If I may;
Why no following of links?
I ask as I'm useless at... is it; psychology? (low EQ)
And want to learn why people will seldom click (my?) links?

Correct!
For higher speeds than a car normally does, but the effect should still help at lower speeds.
It's been discussed quite a lot here.

But... not really the case here as there are lots of other air exits, like into the wheel-wells etc in/out of an engine compartment.

I would hinge the belly-pan in the front (or make it flexible), so that the rear gap is adjustable.
That would allow one to experiment a little and find the optimal opening.

Also you'd be able to close the belly-pan when reversing, which is likely to make said experiment last longer than a day or 2!


Had you followed the link and seen those pics before I posted them locally?

Cooling air flow: Backward rather than downward.? The one where you proposed ducting engine compartment air through the A-pillars?

Well; that's a later idea, in the same thread.
That thread starts with the above, gapped backward flow out of belly-pan idea.
So it's like the very reason for the thread went completely unnoticed because of a link, rather than 2 embedded pics..!??

(When you think about it, the A-pillar idea is just a continuation of this; 'Radiator air out hood vent' thing used in a lot of race cars:

ie: Race cars vent radiator air into the low pressure area of the hood:

To both (Meredith Effect) suck the air out/through
And
negate the unwanted lift in that area.

ie: Just do the same on the roof low pressure area.

I cant speak for others, but for myself it's mostly a combination of being tired from working almost 80 hours a week (Like all good Americans must if we wish to truly "Make America Great Again" /endrant), and having a short attention span from unmedicated ADHD...

I used hood vents in my race car for this very purpose, though I'll admit that I goofed a little on the placement of the center vents and once the hood is cut it's cut, so oh well I guess...
