... I know they put it in Need for Speed - Shift and in Shift2.
There you can hear heavy breathing from the driver when you hit a wall or something like that and I think Shift2 is rated for 3 years old children.
But if you want to see heads ripped off by flakexplosions and blood spilling all over in the cockpit, for the realism, or a rear gunner with all his guts hanging out because he was hit by machinegun fire in his belly,... maybe you ask the developers if they want to bring out a 2nd version of the game, only for adults.
I personally would be already pleased if they iron out the existing deficiencies.
