I was thinking the same, especially the lawn edging.

Also, I was thinking that you could back it with spongy foam to act as a spring. It would be light-weight and would allow the coroplast to compress/bend up and bounce back after hitting a speed bump and other urban predators of low-profile air dams. If the foam is integral to the air dam support structure, it would need to be "rigid" enough to withstand highway "wind" speeds (i.e. 60 MPH).
