It is necessary AFAIK to drill the screw or bolt holes oversized and install grommets in the holes to insulate the plastic from any shock or concentrated pressure from the fasteners. I've used screws and bolts with shoulders to install plastic windows to prevent over tightening cracks in the plastic.
From reading his site I think his concern about using screws involves twisting forces. As to the race car, well the windows need only last for the length of the race, these need to last through summer/winter for years. Still, I see many screwed down plastics. I'll ask him when I call.

I like the gromet idea.
