There is no published textbook evidence that supports a template being used in these ways, and a single day of on-road testing will quickly show that these purported uses are incorrect.

Now do you see how far down the rabbit hole of delusion people are here?

The whole foundation on which many people here have built their aerodynamic understanding is completely wrong.

Why? Because they've been systematically and persistently misled over a long period.

Trouble is, to admit that is to also admit to being utterly sucked-in to believing in garbage - and clearly (with just 2-3 notable exceptions) people would rather continue to be wrong in their understanding than admit to having been so completely fooled.

Thanks for the helpful hint there. I was under the impression if I boat-tailed my car I might get a little better fuel mileage. Oh well. I guess I'll go back to trying HHO generators.
