I have been told that, if I am to continue posting here, I am not to address any posts that Aerohead makes. That is unacceptable to me, because unfortunately Aerohead is the greatest source of misinformation on this subgroup i.e. the one about car aerodynamics.

What he posts here falls into one of four types of posts:

- completely wrong - that is, utter garbage, that no-one versed in the field would ever support (about 40 percent of his posts)

- misleading in context - that is, because of what is *not* said, quite misleading (about 30 per cent)

- misleading because Aerohead has been proved utterly wrong and is fighting a stupid rear-guard action where black is white (or vice versa) - about 20 percent, but rising quickly.

- really good and interesting posts - about 10 per cent.

Apparently, the owners of the website are happy with this this mix, no doubt because page views are good when such misinformation is being spread without challenge.

As a book author, I find such an approach impossible. In my books, I go to endless lengths to try to nail everything down correctly. For example, in the aero history book, Professor Jeff Howell and I sometimes had 5-6 emails back and forth, all about one tiny point on a single page!

Doug Milliken (one of the most famous names in the field of vehicle dynamics, ever) with whom I am working with on my current history of suspension book, is even more pedantic! (Which is great.)

It is all light-years from the approach taken here: and I just find it impossible to switch effortlessly between 'anything goes' and 'here is the definitive account'.

A few weeks ago, I was told that I couldn't address Aerohead's BS in this forum - and I have considered how to respond since.

I am really sorry, but I think that getting real and credible information out to car modifiers is actually really important. (Why? Because I spend hundreds of hours modifying cars. Yeah, strange I know. Who else would care about such a waste of time of heading in wrong directions? Certainly some here who never lift a finger to do anything real in car mods - it's all just a game to them.)

So unless there is a dramatic change here, goodbye. It will certainly save me many hours of thinking and typing!
