It is not uncommon for all or a portion of a "conventional" roof to collapse in a roll over. So, if a track is concerned enough about safety to arbitrarily ban convertibles then they should also require steel race cages for other cars.

I know you refered to Z4....
But I know of a Z3 that the windscreen did not hold up during roll over.
