Someone makes an admittedly lame jokey stereotype about the US.
A bit like a broad stereotype about the French liking baguettes, the Scots hating Scots, the Brits having bad teeth and talking like Austin Powers, or Germans not having a sense of humour. Even the Germans don't get offended. They've been taught that this is meant to be funny, and that the rules of etiquette suggest they should not be offended by it.
But the real punch line is always some humourless Americans taking it at face value and getting genuinely offended. "They're saying we don't have public transport. They're clearly idiots!"
Do any of you see times square on various holidays or have been to a parade?
No. No one outside the US has ever heard of New York. Just like everyone in the US drives a pickup truck everywhere. lol
