They figure how fast everyone was going, do the math on
the forces involved on the bumper in the accident, and prove that the
weak link was the hitch that let go. They can prove that a properly
designed hitch would have held under 2X to 4X (or more) of the forces
involved in that incident - so whoever made that hitch is at fault.

Baloney.

The (Florida) law requires a hitch to be of "sufficient strength to pull
all weight towed thereby". There is no "proper design" beyond that. The
performance in a *collision* is of no legal significance. The liability is
strictly with the at-fault driver(s).

By your "proper design" theory, you could be sued for driving a Hyundai
instead of a Humvee. It's your fault you got hurt riding in a tinfoil car,
not that somebody rear-ended you.

You can beef up your vehicle to take a meteorite hit, but it will be no
more or less liability in a collision.
