I recon those who drive 10-15mph below the limit when it is perfectly safe to drive at the speed limit just like the idea of being in control of the car behind.
Or...
they lack confidence to drive faster
they're not in any hurry, so don't see the need to go any faster
their vehicle is limited in some way (running on a space-saver spare, power:weight ratio slugged by a heavy load, autobox/ECU dropped into limp-home mode)
Theres nothing wrong with driving sub-limit when conditions are good for at/ever-so-slightly-above-limit drivng, if the driver makes the effort to reduce the effect it has on other road users, but there are going to be times when it's not possible to avoid some disruption to anothers journey.

My beef is with those who do about F O U R miles an hour over speed humps.....

I have overtaken a few of those in my time.
There are a few humps I have to drive over on a regular basis which if taken at anything more than a brisk walking pace would be bloody uncomfortable for anyone inside the car, and would also risk damaging the car itself... This is whilst driving an Omega with standard suspension, wheels and tyres - no massive ground-scraping bodykit additions or lowered suspension to cause ground-clearance issues, yet I've had the bottom of the front moulding hit the ground whilst going over a particularly high hump at about 15mph, and with just a slightly heavier load than usual (to the tune of one extra passenger and a PC in the boot - Dell, not Metropolitan

) I've managed to scrape the exhaust on the angled edges of some newly installed humps - first one we took at 15-20, next one we took at a crawl, same result. Been over them again with just two people and an empty boot and got away scrape-free, so I'm guessing the clearance is marginal.
And then there's those evil narrow rubber bumps most often found in carparks, where negotiating them at any speed gives you the feeling that your suspension has just had several 000's of miles knocked off its useful lifespan...
...now, having said all that, if a driver really is taking the piss, then may a plague of Gatsos rain down upon them for all eternity!
