I think that the definition of speeding is somewhat subjective, really. Local or state government sets a spped limit based on criteria I am not really sure of in most cases (some cases, such as heavily residential areas, are obvious enough, but when it comes to rural or highway limits, I'm not convinced all the time). I say speeding is subjective because I believe that there are many factors to consider, including but not limited to the skill and experience level of the driver, road and traffic conditions, weather and visibility, and the performance (and braking) capabilities of the vehicle being driven. I guess I drive over the posted speed limit most of the time, but I usually don't consider the speed that I'm traveling at to be excessive for the conditions. Slow drivers tend to irritate me, but that neither makes them wrong nor me right.
