Read it again. "I also laid on the horn; for which I received a pair of one finger salutes from the backseat passengers before the car took the next off-ramp." Obviously they got back on after we passed; I check my mirrors religiously, but then one set of headlights tends to look like another during night driving, and there were a lot of headlights. When we were at the rest stop there was a couple of minutes before they showed up, so obviously they were quite aways behind us once they got back on the highway. I don't know what they did in the interim; all I know is what happened when they arrived.
