I’m not so sure I’d dismiss the link between Frontier and low-class passengers so quickly. The LCCs do seem to attract some sketchy characters. And as for Mercedes, BMW, Audi, and other luxury cars, you’d think that for the price of the car it would come with turn signals and the ability to stay in the lane. There’s a link there too, I’m afraid. Those brands attract a lot of arrogant, self-important drivers who ignore safe driving practices here in the States. Their punishment should be a flight on Frontier.
I've seen low class passengers on almost every airline I've flown on. If you have a Facebook or Instagram account, search for account: passengershaming. The was a thread on it here not long ago. I think you'll realize very quickly every airline has their fair share.
As for German performance brand vehicles, if by chance you are referring to my earlier posts, you are missing the point. The point is, unless F9 employees provided the booze that got him to this level of intoxication (which we don't know at this point), this has nothing to do with F9 other than this particular passenger happened to be flying F9. I used drunk driving as an example to draw parallels between blaming F9 for this man's behavior and blaming an auto manufacturer for a drunk driving accident. I used BMW as this is the brand I own. And for the record, I use my turn signals religiously.
IMO, this passenger is an adult who should be more than capable of acting in a responsible manner, including making the sovereign decision to cut himself off, barring any medical issues like alcoholism. I'd expect an adult to behave appropriately in the setting which they are in. I'd also expect that an adult would take responsibility for their actions and not try and pass blame on any other entity. Airlines are in the transportation business. They are not in the business of hand-holding or babysitting adults.
