Very true this bit. The crashing physics in Grid was quite astonishing, and the engine has to take into consideration ratio mass of the car + weight + velocity + the solidness of the object it impacts with + the shape of the part of the car that impacts with the object and so on and so on. Forza 4 will apparently have the most realistic crash physics of any racing game to date (or so they've said). Not just crashing though, turning, accelerating, braking, even gravity for when the car jumps off a steep slope when going fast (it has to calculate the velocity with drag and the weight of the car to give an approximation as to how the car would react whilst in the air and how it would react when landing back on the ground again along with possible wheelspin from coming back into contact with the floor AND how the suspension would react also).

When you consider all of those, and that's just a few of the hundreds of physics a racing simulator has to do constantly, making a character in a war game run or jump up and down realistically seems pretty mediocre.
