The peaked roof doesn't [appear to] add frontal area, but it has severely compromised rear headroom. The peak angle is 204° so the brake is only 24°. The long vortex generating edges fore and aft reduce the air that goes directly over the top. There is no bed/cab gap.

1) CYBERTRUCK has six body widths.
2) From nose to tail, the body is broken into five different planes.
3) It absolutely has plan-camber and plan-taper.
4) The $ 1 HOT-WHEELS die-cast model even demonstrates this architecture.
5) Consider the roof peak in connection with DOT/ NHTSA roof-crush, rollover requirements, and structural (truss ) triangulation.
6) The air comes off the top of the windshield at an 74-degree angle of layback.
7) The air comes onto the roof at a declination angle of 6-degrees, a 22-degree turn.
8) The air leaves the top-rear at 9-degrees ( Ahmed's drag-minimum ).
9) The beltline is positively inclined @ 2.75-degrees,on a tumblehome'd ramp, perhaps developed in R&D to 'tune' out edge-vorticity, one of the most critical considerations which can be considered for a fastback. An industry first ( hope to know one day ).
10) You may want to postpone any comment as to edge vorticity, anywhere on the body, until after careful consideration of the pressure gradients they're immersed within.
11) Yes, the cab-bed gap on Spirit cost 16-counts.)
12) I've not sat in the rear of CYBERTRUCK and have nothing to contribute on that topic.
