Daniel, What you state may be correct, but take a look at the Garmin GPS in-car units. They update speed extremely quickly, and track a car's speedo accurately. I'm not sure how they can do that (maybe in the ways Neil points out), but I am impressed at how well it does work, so much so that I'd like to try using an iPhone app (or just get a Garmin) instead of outlaying a ton of cash to fix my car's speedo proper.
