I don't think I particularly take the numbers into account - once you're used to a car it's much more about where the needle is pointing - you kind of get a feel for it visually on that basis. Thinking of it as a clockface, 6 would be 0mph - if it's in the 9ish range I'm within the limit for town, 12 is about right for out of town, maybe 1, even 2 on the motorway.
There's a surprising amount of wastage there - my speedo goes up to speeds way beyond legal, which wastes space - and therefore precision at lower speeds.
My previous car had a digital speedo, which made it impossible to get that rough glance "am I in the right ballpark" view of speed. On the other hand, the (illusion of) precision probably kept me under the speed limits due to the difference between being able to tell myself I was doing "about 30" and the car telling me I was doing exactly 34...
