The best side elevation photograph of the EQXX that I could come up with, short of a 'blueprint', indicated that it's tearing edge intersected the roofline contour of the 'Template Part-C', as did Lightyear Zero, Hyundai IONIQ-6, Tesla Model 3, with optional carbon fiber rear spoiler, and some others.
If we had wind tunnel smoke-flow imaging of the these cars, we could see the point, and elevation of where the lowest streamline filament begins to deflect, above, or below the nose, which would also indicate the elevation where a 'long-tail' would terminate, and the streamlines would rejoin there original, un-disturbed location in space. This would also allow measurement of the total distance traversed over or under the body, closest to the surface boundary, allowing calculation of instantaneous velocity and pressure at any point along the pathway.
The wake areas versus frontal areas, and Cds would allow comparisons to the results PhD Jeff Howell et al, at Loughborough University experience in their 2D, and 3D Windsor Body boat-tailing research.
