I used to think these people were rude, then I thought they were stupid. After a long time, my brain cells took over.
These folks generally mean no harm. They are interested in the beautiful vehicle in front of them, they don't understand them, and they want to say something profound or at least appropriate. But the knowledge they have could be put on the head of a ball point pen with enough room to roller skate around.
I listen, and if the speaker gives me some sort of eye contact indicating that he's simply showing off for his date or 9 year old son, I'll bail him out as if he was the pro. If he's trying to demean, insult, or help me diagnose his learning disability, I ignore him and turn to stone.
I love these vehicles. I work on 'em and enjoy chasing the threads, for crying out loud. I study their technology, and I'm amazed that technicians and the true mechanics from 80 years ago made them work as well as they do. Observing the technological "stair steps" that have occurred since then, (each generation building upon the success of the prior generation), I would love to be here 100 years from now to see how things have progressed.
PS... Do you think that they will ever produce a wind powered vehicle for our politicians?
