Although it might not have been a true suicide attempt. You'd have to be a real dimwit to attempt suicide in a Hummer. The idea comes to mind that she may have wanted to impress/control/punish the "someone" she had argued with, and used the Hummer because she felt that it would protect her enough to prevent serious injury. Not very bright.
Hmm, sounds like a good lawyer could sue the manufacturer of the Hummer vehicle for the unexpected results of the plaintiff's attempt to feign suicide, in that the Hummer brewed up like a
Sherman Tank unexpectedly, when the vehicle was marketed by the company as being built like a tank and could easily manage a quick off road detour down an embankment into some small trees without the driver being injured.
