I've seen what an unlatched hood can do at highway speeds. It will rip the hood right off the dampers and smash the windshield. FSD won't help you.
I guess these Teslas have “suicide frunks”!
I imagine either regulations and/or good engineering makes it safe to drive with an open but latched hood considering that you can pop the hood while driving by accident.
