not really ..... if the ship is not buffetting why would the pilots head (your body/neck acts as a damper
) ..... I have run into all sorts of low altitude turbulence ..... and it never does to a plane/glider what it does in IL2 or that vid ...... as RAF Winger confirmed there is nothing close to that kind of amplitude or violence.
The comment about dropping a wing or a short 'bump' are much more accurate.
