I'm not sure whether the same issue affects Chummies, but one of several reasons I never use the hood bag (or indeed the hood) on my Ulster is that it inflates as you drive along, largely blocking any view to the rear. A central strap was installed in an attempt to curb this, but didn't make a lot of difference. I think it's not so much a rush of air getting in at the front opening, as negative pressure above which 'sucks' it upwards. Given several other negatives, it generally resides somewhere in the garage loft space.
