I'm one of those odd drivers who tries their best to drive at or below the posted speed limit. I include the word below here as sometimes there is a need to slow down to less than the posted speed limit for safety reasons. This often has consequences for me when I have to share the road with other drivers who do not subscribe to my philosophy on road safety. A good example of this is looking in my rear view mirror and finding the Volvo logo on the grille of a heavy transport truck following me closely enough that I could count the bugs stuck to it.
