The windshield is a structural part of the vehicle and performs a
function in rollover strength. The molding doesn't contribute much to
this aspect. The molding is not only aesthetic though. The edge of the
glass must be protected from any nicks whatsoever or the glass will
crack. It takes almost nothing on that edge to produce a crack either
at the time of the incident or weeks later.
