It's all in the mounting.  We've done suspension development for several 
years with in-car PCs, usually providing a GUI and data logging services 
for '332-based controllers (those TPUs _are_ mighty useful).

We beat the crap out of our suspension cars, and the old PCs have kept 
right on ticking.  Remember that street cars are quite softly sprung.  We 
rarely see peak vertical body accels above 2g, and then only momentarily.  
If the slightest effort is made to mount the PC correctly, it will never 
see enough acceleration to disturb the boards, and high frequency vibration
will be almost non-existent.
