    <!-- Kart's center point:
        gravity-shift is the shift of the chassis with regards to the center of
                      mass. E.g. with the the value commented out below the 
                      chassis will be 30 cm higher than the  center of mass - 
                      or the center of mass will be 30 cm lower than the  
                      middle of the chassis. So this effectively lowers the 
                      center of mass, making the kart more stable and less 
                      likely to topple over. Default (if nothing is defined 
                      here) is that the center of the mass is at the very bottom
                      of the chassis.  -->

         backward-up-angke: Angle between camera and plane of kart (pitch)
                 when the camera is pointing backwards. This is usually 
                 larger than the forward-up-angle, since the kart itself

         its maximum speed (in m/s).

         the kart stops using nitro (and the fade-out-time starts).

    <!-- min-speed-radius and max-speed-radius define the smallest turn 
         radius at lowest speed (4.64 m at speed 0) and at high speed
         (13.5 m at speed 12 m/s). Maximum steering angles for speeds 
         in between will be interpolated. This allows for tighter turns
         at lower speeds. The actual steering  angle is dependent on the
         wheel base of the kart: radius = wheel_base/sin(steering_angle)
         By specifying the radius the steering behaviour can be defined 
         independent of the kart size. 
         time-full-steer is the time when a player's input goes from neutral
                         steering to extreme left or right.
         time-full-steer-ai is the time for the AI to go from neutral steering to
                         extreme left (or right). This can be used to reduce 
                         'shaking' of AI karts caused by changing steering direction
                         too often. It also helps with making it easier to push the
                         AI karts (otherwise micro-corrections make this nearly
                         impossible). A value of 1/maxFPS / 2 will guarantee that
                         the wheel can go from -1 to +1 steering in one frame, 
                         basically  disabling this mechanism.       -->
