Well stated argument! I always wondered why your car sometimes launched to the sky in Stunts, from 1990. Yes, you could have for example energy limiters and total momentum checks in your algorithms. Energy can not be added in a collision. In a collision between two finite mass objects, total momentum is preserved (you can't use this with collisions with the ground). Maybe games already do this? You could also just fudge the equations to avoid singularities, like always add +1 to the divider. This could probably cause other problems though.
