i'm betting that if schroth has DOT-approved belts, they're the ones with
retractors in them.

interesting rule. passenger looks over at driver and says "if i go down,
you're going down with me!"

what angles were tested? did they test with the belts angled down
below the vertical? how far down?
various racing sanctioning organizations limit angulation to no more than
45 degrees, and that's based on a lot of research. so i'm interested in
this testing you cite. can you be more specific about where to find it?
