I'm an RV'er, a former dump truck and OTR driver, and a "to the core" biker (notice that I did not say motorcycle enthusiast which so many riders today are).
Yes, bikes are fast and maneuverable, and should quickly and easily pass the average RV. Often the rider's sense of timing and knowledge of vehicle operation are not up to the task and accidents happen. This is a sad fact of highway safety. As an RV'er I suggest just maintaining your speed and direction. As a rider comes up behind you to pass they'll calculate their passing based on your motion, any change in your motion can throw them off and make for a dangerous situation, just let them pass you. Wave hello if you choose.
Also, regardless of how you feel about the riders and how they ride, do not do as I've had some do to me. Some drivers consider it their obligation to show a rider that he or she should not pass and the driver will then proceed to block them (I've seen truckers, RV'ers, and car drivers all do this). If you ask me this action is nothing less than attempted homocide and I have been on the receiving end of such "driving lessons" before, luckily I can ride better than they could drive. Don't forget, if a bike hits you it will do far worse damage to the rider and his vehicle than it will to your rig, that rider does NOT want to get too close to you.
Bikes tend to be symbols of a certain freedom of the road and due to their speed and maneuverability they are often used that way in traffic, hence the land splitting, white-lining, and cutting in front at traffic lights. You cannot stop it. Any attempt to do so might kill the rider and put you in prison for the rest of your days. All your complaining about this will be to naught. Education of riders is the key, but even then there are people who will heed the sound of the wind rushing past their ears and use their bikes to avoid traffic and find a piece of open road. And I wish them Godspeed!
