Whatever it is it COULD be 8" lower. Just look at the Jay Leno/Elon Musk video. Jay is not super tall at 5'11" but he has SOOO much headroom. Musk does too at almost 6'2" and they are both sitting very upright. Somebody 7'6" could sit in there without reclining the seat at all.

You do understand that the leading and trailing longitudinal edges are pulling air around the top, reducing he volume that goes straight over?

True, but how are you going to wear a ten-gallon hat? That's really important in the pickup capital of the universe.
If you like speculations, I believe that NHTSA rollover/ roof-crush structural safety standards have something to do with CYBERTRUCK's 'truss' roof. The second speculation has to do with providing and aerodynamic trip-strip, right where it would count.
In addition, in the near-impossibility of a rollover event, that 8-inches might make the difference with respect to a spinel cord injury and permanent paralysis, learned from Ford Explorer and Expedition crashes. You may 'survive,' but perhaps paralyzed for life.
CYBERTRUCK is the 'lowest' pickup offered so far. I agree in spirit with 'excess' headroom. I vomited when Volkswagen brought out the 'New Beetle' and 'New New Beetle.' Asinine headroom.

I thought we were talking about a comeback, which could happen as soon as television tells us it should happen.

Top, sides, or bottom?

I have no confidence in their capability to represent reality. I've seen them ascribe Cd 0.46 to a RAM pickup with a Cd 0.36 published by Dodge.
Lamborghini constructed a car with a forebody quite like CYBETRUCK. Hard edges and all. Photos show tufts in perfect attachment.
And Lamborghini did not have a favorable pressure gradient all the way to the middle of the car as Tesla.
Their beltline was not raked as with Tesla.
Frederick W. Lanchester's book, Aerodynamics, 1907, clearly lays out how CYBERTRUCK's nose works with virtually zero aero penalty.
Seems like Franz von Holzhausen is a genius.

What I really want to know in freebeards graphic: what is diverting the straight flow? Newton law #2 hints stuff doesn't go hard right for just S&G

[freebeard]

I find it believable because the venerable Beetle, with it's external rain gutters, approximates the back half of the Cybertruck. Whether the front edges, in a positive pressure gradient, would perform as advertised is an open question. aerohead's 'trip strip' might be more 'to the point'.
