I am surprised that overhead bins are not locked when the plane is in motion (i.e., not sitting parked at is origination or destination gate).

This would help with the idiots trying to drag their luggage out with them during an emergency.

And it would probably help with the inconsiderate who carry ridiculous amounts of carry-on hogging up all the bins. Once they found out the only thing you can access during the flight is the "personal item" that fits under your seat. Actually, under the seat in front of you, so that your personal item impacts your leg room, not somebody elses.

I'm talking remote controlled locks where one button push from the cockpit could lock/unlock everything at one time.
