We have those kinds of issues on cars ...

Here in the 'States,' roof strength regulations are pushing stronger 'pillars'.
Pedestrian safety regulations are raising cowls.
The submerged cowls may also have to do with safety,and to provide enough pressure for fan-off ventilation.The depression,locked in by the A-pillars may have to do with fresh air as much as drag.
So far,there are no low drag concepts with this submerged cowl.
