In Eastern Europe I regularly hear that car disintegrated into three pieces or engine fell off after a collision. These do not happen to a car having minor crash in its history, these happen to a car which had been totaled in the past. Eastern Europe is the scrapyard of Western Europe and yet its inhabitants found a way to fell superior about their 15 years old BMWs with engine mounted on three screws.
Some modern cars are specifically designed with frangible engine mounts to eject it downwards in a frontal crash. This is a safety measure to dissipate energy and prevent the engine from being pushed back into the passenger cabin.
