feat(vehicle): an uneven track shakes the cab by itself

Browse Source 
On such a track the sway drawn from the lateral acceleration, that is
from the curve radius, and the jolts drawn at random are off. Tracks
with no unevenness shake the cab as before. Hunting stays: it goes by the
vehicle and its speed, not by the track.
