Electric Vehicles

It wasn't unique in small American cars in those couple decades (notable for rushed designs with an indifference to safety across the board) but the numbers were a bit worse. They stood out for Ford's extensive crash tests, and well-documented knowledge of the lethal design flaw, their early decision to pay out for deaths rather than make a quite inexpensive design change, and recall, and for the decade of expensive legal battles and PR campaigns where they lobbied against federal rear-end collision safety requirements which would have saved lives and identified the problem. They were happy to throw money at every aspect of the problem except for the part that kept burning their customers alive.

Also it wasn't just the gas tank design but flaws with the frame and (essentially cosmetic bumper) which jammed every door even in minor rear end collisions.
