Really? Just what, exactly, does the phrase "well proven to absorb enough impact to help prevent this" mean? How much impact, at what angle?
Your views appear to differ from those of the CEO of the Snell Foundation, which tests helmets. In 1999 he said that the weight constraints on bicycle helmets made it impossible to make one that was effective in accidents with motor vehicles. It is indeed the car hitting you that you have to worry about, and in such cases the helmet is so massively overmatched as to be irrelevant.
