Limitations of 3D Physics Engines: Unintended Explosion

Inherently unstable objects are difficult for most simple 3D/game physics engines to accurately simulate.
A rigid car frame sitting on wheels and ball bearings is shown in this example. A multitude of forces are constantly pushing on the ball bearings and the ball races.
These forces are very small, and the physics engine has a hard time accurately simulating the forces and positions of the objects, which results in small unnatural movements.
These unnatural movements are not dampened, but instead compound together into violent shaking and finally a powerful explosion that blows the ball bearings and the entire car apart in a shower of force/position errors.
