Detroit: where'd you get that?
Anyhow, no a car PROBABLY woudln't flip unless really weird circumstances arose (say it snaps right in the middle of a 90mph turn at an autocross and the driver loses control? or some other very silly and almost impossible senario). Anyhow, the result would likely be just a very very ticked off driver at a stop light or driveway, or perhaps a sudden "no power" in the passing lane going 80mph on a major interstate......*wreck*...
ya, basically, get that stuff fixed now.
