Analogue instruments may not be as accurate as digital ones but they
have a hysteresis that damps the movements and stabilizes the readings,
especially bi-metal ones, that with the easier interpretation by
position of the hand (it is OK if somewhere near the middle) rather than
reading the actual figure and interpret what it means makes analogue
instruments in cars far superior to digital instruments.
