What they need is a giant sliding bar (like in old jail cells) that locks the overhead doors shut on takeoff, and won't get released until at the gate. Last time I flew on a commercial flight, I got clocked in the head by some jerk who couldn't think ahead and put 'something important' in the overhead. I think it would be fair to carry the small package under my seat (my laptop), but reaching for overhead is a joke.
