The noise in the system made with many atoms and electrons etc is probably 
inevitably much bigger than the inevitable discreteness imposed by atoms and 
electrons in the axle. The discreteness imposed by the discrete nature of most 
physical things is on a very small scale indeed in most circumstances and is 
only observable in very noise free situations which also amplify the 
discreteness. Is an unmeasurable theoretical discreteness in a measurable 
quantity a discreteness in that quantity? Lots of semantics and definitions here.
