Yeh, what I meant was it would be tricky to get the vibration looking 
anything like realistic.  Without simulating it properly (which would be a 
horrendous task in non-linear vibrations and FEM) I guess you need to think 
of a simple algorithm to determine the camera displacement at each frame.

My first thought is to define some macro that determines the camera 
displacement as a function of distance along the track.  Some sort of noise 
function, like Perlin noise might do the trick.  That way, the faster you go 
the faster the camera will vibrate.
