Isn[t there still a mile marker every mile on the Interstate, and indeed on 
most Federal highways?  I usually go by the tach at 3000 rpm in high gear, 
and time by stopwatch over 5 miles; this gives a simple check, and the 
observed error is pretty correct as a per centage for other tach readings. 
My cheap tachs usually work better than the speedometers in my late models.
