There's no better way to test it out in your area than to try it once, or twice, or for an entire tank. As long as you keep to the right, don't cut people off when you have to get out of a lane, etc, you'll be fine. I drive 55mph now and if my lane is ending I always wait for those coming up on my left to pass before I get over. I keep an eye on the mirror to keep track of who's around me.
It's really easy; the more visible you make your car, the less people tailgate, but then I'm going to start talking about "urban camouflage". From what I can surmise, people don't want to follow "official" looking vehicles for the same reason they don't want to drive next to cop cars.
