On mine, I used the curve of the edging itself and the ball end down to increase the rigidity in the airflow. I am sure it does not flex as you theorize. I know because I cannot move it aside to get a Jack under the car unless I use significant force.

have tried and destroyed lawn edging air damns more than a few times
use a tire tread or two for wide applications , on the geo metro a 185 60 15 re 92 with both side walls sliced off to the edge of the steel belts is about
perfect
it will scrape sometimes but it will never break or crack or split or bend out of the way
unlike
the
useless
lawn edging
which will do all of the above in the first 30 days of use

While I have replaced the edging once and had to improve the mounting a couple times, I have seven years of experience across 80,000 miles that suggests it's not useless as you assert. I think it matters how you mount it. I have not had to redo it in a few years now. It scrapes sometimes. Stays in place.
