Absolutely. They're clearly wrong. The regs don't say that and only talks about preference for gliders, balloons, and airships. One an argue maneuverability but I can tell you that an airship is in fact MORE maneuverable than many things it is given preference over. An airship can spin around on a dime. I can't do that with my airplane.
I never said they weren't. I was countering your incorrect statement, "The plane has the right of way in aviation, of course, because it is the less maneuverable vehicle." This is of course still wrong which you've already admitted:
1. The regulations don't say anything about airplanes having the right of way over ground vehicles.
and again
There is nothing in the regs or anything OFFICIAL from the FAA that says maneuverability enters into any of this.
