It's a fallacious, superficial argument premised - as so many of yours unfortunately are - on a rather literal and/or simplistic understanding of what is being discussed.

The rules of thermodynamics haven't changed in 100+ years - but today we don't design engines like those of the 1930s, or even 1960s or 1980s.

The rules of resonant mechanical systems haven't changed in 100+ years - but today we don't design suspension systems like those of the 1930s, or even 1960s or 1980s.

But I for one, will always keep reading historic documents on engine and suspension design - and aerodynamics - because I think the historic context informs current thinking.

But it's a completely different thing to think that it should dictate current thinking.

If you presented historic examples in the context of 'hey, look at this - isn't it interesting?' I'd be applauding what you do. But you don't - you pretend (or even believe?) that this history should be directing what we do now - and that is just ridiculous.

Your approach has unfortunately led you to have lots of mistaken beliefs about what is happening with airflow on current cars and then to - unforgivably* - advise people based on those erroneous beliefs. And you have been very successful - I can see time and time again people on this group parroting the falsehoods you have disseminated.

(*I don't care what you believe - lots of people believe all sorts of weird stuff. But I do care when you are leading others astray based on your incorrect beliefs.)
