Net partition

Hi all

Does anyone know how robust the "net partition" option is likely to be on the Superb 3 ?

I'm wondering if it is strong enough that you could confidently load up to the roofline and it restrain stuff in the event of a frontal collision ?

The word "net" doesn't make it sound particularly strong....but the times when we'd be likely to load right up are when the kids will be sat in the back.
