Some cars, now have nonlinear speedometers. How can they achieve to get different spacing between some speed ranges?
For better understanding, see the image
of an old Audi A4 speedometer.
The range from 70 to 100 is not linear, because there are equally spaced marks, as you can see in the table:
Mark Increment from previous 70 5 (was 65, not shown on this table) 75 5 80 5 90 10 100 10
