That’s not nearly as bad as an endlink. Also, I seem to remember reading somewhere that the decceleration felt in a standard street accident were on the order of about 75G’s. On a 200lb human, that’s 15,000 lbs.

The shear strength of 2 lower grade M10 bolts is about 8,280lbs X 2 = 16560… so you would be “safe”… but not really…

also, the those bolts are not in pure shear, you have a small moment arm acting on the bolt, adding some tensile stress. I’d need to see some geometry to determine what the forces actually were… but it’s pushing it.
