Car.cs Missing things??

I have been comparing the car.cs from tgea and t3d and there seems to be the following code missing. The buggy works sorta, but not very well, so I was going to make a few changes. If this code isn't in the server/car.cs, then where might it be?

//----------------------------------------------------------------------------

datablock WheeledVehicleTire(DefaultCarTire)
{
   // Tires act as springs and generate lateral and longitudinal
   // forces to move the vehicle. These distortion/spring forces
   // are what convert wheel angular velocity into forces that
   // act on the rigid body.
   shapeFile = "~/data/shapes/buggy/wheel.dts";
   staticFriction = 4.2;
   kineticFriction = 3.15;

   // Spring that generates lateral tire forces
   lateralForce = 18000;
   lateralDamping = 6000;
   lateralRelaxation = 1;

   // Spring that generates longitudinal tire forces
   longitudinalForce = 18000;
   longitudinalDamping = 4000;
   longitudinalRelaxation = 1;
};

datablock WheeledVehicleSpring(DefaultCarSpring)
{
   // Wheel suspension properties
   length = 0.85;             // Suspension travel
   force = 2800;              // Spring force
   damping = 3600;             // Spring damping
   antiSwayForce = 3;         // Lateral anti-sway force
};

datablock WheeledVehicleData(DefaultCar)
{
   category = "Vehicles";
   shapeFile = "~/data/shapes/buggy/buggy.dts";
   emap = true;

   maxDamage = 1.0;
   destroyedLevel = 0.5;

   maxSteeringAngle = 0.75; //0.385;  // Maximum steering angle, should match animation
   tireEmitter = TireEmitter; // All the tires use the same dust emitter

   // 3rd person camera settings
   cameraRoll = true;         // Roll the camera with the vehicle
   cameraMaxDist = 4.8;         // Far distance from vehicle
   cameraOffset = 1.5;        // Vertical offset from camera mount point
   cameraLag = 0.26;           // Velocity lag of camera
   cameraDecay = 1.25;        // Decay per sec. rate of velocity lag

   // Rigid Body
   mass = 380;
   massCenter = "0 -0.2 0";    // Center of mass for rigid body
   massBox = "0 0 0";         // Size of box used for moment of inertia,
                              // if zero it defaults to object bounding box
   drag = 0.6;                // Drag coefficient
   bodyFriction = 0.6;
   bodyRestitution = 0.4;
   minImpactSpeed = 5;        // Impacts over this invoke the script callback
   softImpactSpeed = 5;       // Play SoftImpact Sound
   hardImpactSpeed = 15;      // Play HardImpact Sound
   integration = 8;           // Physics integration: TickSec/Rate
   collisionTol = 0.1;        // Collision distance tolerance
   contactTol = 0.1;          // Contact velocity tolerance

   // Engine
   engineTorque = 3300;       // Engine power
   engineBrake = 600;         // Braking when throttle is 0
   brakeTorque = 8000;        // When brakes are applied
   maxWheelSpeed = 50;        // Engine scale by current speed / max speed

   // Energy
   maxEnergy = 100;
   jetForce = 3000;
   minJetEnergy = 30;
   jetEnergyDrain = 2;

   // Sounds
//   jetSound = ScoutThrustSound;
   engineSound = BuggyEngineSound;
//   squealSound = ScoutSquealSound;
//   softImpactSound = SoftImpactSound;
//   hardImpactSound = HardImpactSound;
//   wheelImpactSound = WheelImpactSound;

//   explosion = VehicleExplosion;
};

It really surprises me the car has wheels and works at all unless this code has been moved.
