What is wrong with courtesy - and sharing the road?
Advanced riders here in the UK are taught that you should pull over for people who want to ride faster than you, even if they are exceeding the speed limit. By blocking them you are probably raising their blood pressure and encouraging them to do something dangerous - in which case you are an accessory in the moral sense.
I believe that not pulling over to let a faster rider through is bad manners - whether you are on a Goldwing at 15mph or mounted on a Yamaha R1 doing 110mph.
I am not in any way condoning breaking the speed limit or treating the highway like a racetrack.
