If it is measuring acceleration and time, It not only knows how fast you
managed to go but how far you went, eh?  (given x=v=0 when it starts to
measure).  More of that math stuff, is all.

So if you stop accelerating at "55" while trying to measure "0-60" it
either has to extrapolate or it likes being lied to... and isn't smart
enough to be able to tell.  Hmm, the ideal voter.
