Sorry, now you've lost me. I am interested in modifying cars - as was my belief, were most of the people on this forum.

Automotive...since there is no thread on heavy lorries, I assume that means cars.

Yep, and I guess we're all waiting for you to show a practical, real-world car that drives on highways and has lower fuel consumption because of its aero lift.

If it were as easy as this, don't you think that, like, it wouldn't be being trumpeted from the roof tops and every carmaker wouldn't be doing it?

And I can assure you, they're not.

You may be, I don't think anyone else is. It is a theoretical discussion.

Theoretical discussions aren't worth the electrons they are written on. You as may well have a theoretical discussion about zero drag vehicles.

Great for people who apparently don't do anything real. Not so good for people in the real world of car modification.

Honestly, FFS!

I don't think good or even proven ideas always make it into actual production cars. In the end, all manufacturers want to do is make a vehicle that's close enough to what people want in order to sell it and make money.

An example of this is the Aptera. Lots of people here have complained about how they don't like the looks of the Aptera. We know boat tails work, but people don't want them.

There are even a lot of people who don't like the shape of the Prius just because it doesn't look like a normal car.

Car manufacturers are pushing for "coupe" SUVs and CUVs because they are now aerodynamic than the typical box-butt SUV or CUV. But there are probably a lot of people who don't like that either.

Now add a bunch of airfoils on a vehicle so that it lofts party if the weight off the ground... Who wants a car that looks like it was built by a mad scientist.

I would... That's one person in 8 billion. And I'm not a new car buyer.

So what isstopping you from doing that and showing people you're right?

Methinks there is more to heaven and earth than fit into your schemes

That's incorrect.

Maybe because I'm lazy. Since I've joined Ecomodder about the only "ecomod" I ever did was I added a grid plate underneath a carburetor and rebuilt an engine trying to make every eco-friendly choice I could within a budget. My current cars, the Avalon and the Prius, are unmodded, except a lousy OEM block heater on the Avalon and a few grill blocks I've had on three different cars that I don't notice do anything except cause the engine to overheat once I go out of town on the highway.

Another thing too is that I've started a couple of aeromods before and my wife didn't like what I was doing. She doesn't want to drive around in a vehicle that's got a boat tail or wings on it. Maybe once I get the Prius running I'll start modding it. But then again, we always go out of town on the highway together in the same car. Around town the speed limit is 25mph townwide except the 35mph main highway that runs through it. So any aeromods or wings would be pretty much useless, other than to take once on the highway just to try to prove a point and nothing else.

unpacking Julian Edgar's logic

Most people let your sort of comment pass (just like they do with: "there are no stupid questions") but if people keep spouting garbage and no one challenges, then it just goes on and on.

I showed the silliness of that notion very easily with my moon/cheese example. If you can't see that, that's fine: keep voraciously chasing mirages. But for me, and most people I professionally deal with, that would be a waste of a seriously finite life.

Instead it is far better to say, "When confronted with a new idea, I ask for the evidence for that idea, and then weigh that evidence up carefully".

[Shrug] I can see lots of stuff here that has taken on a life of its own over the years (eg The Template), where there was a severe lack of evidence but it was adopted wholeheartedly* - so maybe what you say is of no surprise.

*Yes Freebeard, I know you occasionally demurred.

I just see so much rubbish circulated re car aerodynamics that one starts to wonder what intellectual rigor (propositions; evidence for those) people are actually applying. Usually, very little or none, I think.
Julian's comment was not directed towards me, however, he never loses an opportunity to attack me, so I thought I'd throw in my three cents:
1) ' a moment of thought' ............... typically the source of much consternation, as brain ejaculations may be followed up by thinking, perhaps up to a month later.
2) any comment concerning 'rubbish' would imply possession of critical thinking skills, required for discernment. In over a year now, I've never experienced, by observation, that these discernment skills ever existed.
3) comments about 'most people' imply firsthand knowledge of what most people think. A rather ridiculous proposition coming from the son of a scientist.
4) people have been burned at the stake for espousing 'garbage' ideas, which are currently held as universal scientific fact.
5) Rules of etiquette allow for a 'challenge' which doesn't attack or rob a person of their dignity. If your personal constitution demands that you play judge, jury, and executioner, then I suggest you take that elsewhere. You've made EcoModder.com an unhealthy environment for over a year.
6) Mr. Edgar's particular network of professionals doesn't appear to include anyone ever involved with low-drag aerodynamics, something I'd presume would be a prerequisite.
7) When Professor Alberto Morelli presented his 'evidence' for a low-drag road vehicle in 1976, it consisted of a bunch of numbers on a page, derived from a two-dimensional fluid dynamics model from 1947.
8) Morelli commented that ' it is possible to develop from theoretical considerations ideal shapes aimed at reducing drag to a minimum..........'
An 'idea' which became fact that year.
9) on a least seven occasions, I have presented the scientific origins and scientifically-derived, empirical test data, supporting the 'template.' Julian Edgar has never addressed this scientific evidence, which I can only interpret as cowardice.
19) as a pedant, Mr. Edgar cannot himself defend his assertions, relying on his select panel of experts, of whom, all communications are filtered through Julian Edgar. I've no idea what was said to them, and what they actually said in response. ( 'To know, and not tell, makes cowards of men.' Abraham Lincoln )
20) It's comical that 'experts', and the corporations they work(ed) for, who allegedly, and completely discount any merit of a 'template', use the 'template' for their lowest drag products.
21) evidence of any self-attributed 'intellectual rigor', in possession of Julian Edgar, will be lost on anyone unfortunate enough to own a copy of his book on aerodynamic modification of road cars. Some of the logic-reversals are of epic proportions.
22) and he'll never know. It's structurally impossible for people to know what they don't know.
23) and the worst thing of all is, that when mentioned in a tactful, diplomatic, and constructive manner, there's never any hiatus, time-out for introspection, just hostile pushback against the possibility of any self-ignorance or intellectual bankruptcy associated with the topic.
When a toy poodle struts into the marked territory of a wolfpack, tail up, hiking it's leg on everything, it can never end well.
Keep on thinking Julian. And keep on thinking wrong. We know you can't help it.
