The crossbars are the wrong shape.Well, first off, racks that are screwed into the body of the vehicle are fine for grounding.
Secondly, you can just screw the antenna directly into the mounting point, you don't have to hang it off a roof rack that adds more drag than your antenna.
The crossbar is a ---, not an X or a *.
A lot of people do hang antennas off the side of their car with fender and bumper mounts. This is distorts the radiation pattern when the antenna broadcasts, and it's probably fine for some applications.
The best place for an antenna is in the middle of a metal roof.
If the roofracks are easy to attach/remove, that may be the solution. I can add ground radials where they need to be, and attach it when I need it, and remove/disassemble it when I don't. But the devil is in the details of how it all goes together.
This is a solvable problem. But each solution comes with tradeoffs. I don't see an obvious winner for most use-cases the way there is for conventional cars (mag mounts and through-hole NMO).
