One thing I noted early on in the launch, the hardpoint brackets do not seem to be mounted in a standard direction. I would think that you would want the mount opening to be towards the front of the car, so that as you attach any accessory, it slides to the rear, and air resitance is your friend. If the opening is put to the rear, any item without a tightened braket might slide back. Maybe they will figure that out later.
Like everything on this car, that was a considered decision.
The force from braking (or impact) was considered greater than from wind or acceleration. Regardless there are 4 knobs that need tightening and a pin/lock that prevents it sliding off even if all the knobs came lose.
