There are some good sources that strongly disagree with these points though. For example, a study done by the sae showed v type 4 point harness to be as safe if not more safe than 3 pt harnesses with no occurrence of submarining in their tests. This study assists limited though as the test numbers were small and the crash scenario was quite limited.

And schroths crash test videos with the 4pt ASM belt are impressive to watch (although I always question when a company does research that so strongly supports it's own claims)

Anyway, thanks for the replies. It's always nice to hear other people's insights and feedback.

If you watch the ASM video, look at the dummy's neck at the 1:20 mark. Thats why a 4pt (or 5/6) with no hans is no bueno
