I don't get it either.

I don't think having the windshield intact and 3" of overhanging roof will protect anyone from anything, nor do I think it would have prevented the Dayton incident.

I'm very much all about alternatives and backup plans.

But as a matter of "routine", I feel we should just clear it all away when possible. Take it all. When not possible, use your alternatives: flaps, flops, flips, flip-flops, etc.

We should always try to respect airbag safety zones inside a vehicle.
