That's a good point. Before Starfleets starts installing seatbelts in its ships, it should probably invest in some better circuitry. Some breakers and well-placed surge protectors would go a long way, also.
This always bothered me about star Trek. They'll put seat belts on Captain Picards dune buggy and the captains chair..(see nemesis deleted scenes) .. but the inertial dampeners will fail when a ferengi farts and no one bats an eye.
And why oh why is all that power conduit juice streaming through consoles? Ive never understood the need to have a console explode in ones face. It got old after the first few times it happend in TNG
