Please forgive a tired old man's failing memory & question.  I know I knew (frustrating as hell) what the trailing wheel was for, but can't recall it.  Was it a calibrated speedometer?  Slip angle detection?  Wheelspin detection?  None of the above?

Thanks,

The fifth wheel, in Germany called Peiselerrad after its manufacturer, is a calibrated instrument for length measurement.

therefore gave accurate speed data during acceleration testing.
They probably use GPS-derived data nowadays.
