I fail to see why people think this makes the things completely unsafe.. Usually things are designed with multiple failsafes, and on top of that.. the safety factor has to be multiple times the expected loading etc. So far, at least as far as my understanding, this is a very small part of the system not like the entire chassis collapsed on a car, or caused the vehicle to suddenly derail. If those massive system fails occurred then yes safety would be compromised. As of right now, with the people in the know, and what has been shown, this is closer to a car tire losing a lug nut than an axle snapping.
