My autistic neighbor has an imperial seal on his car...
We don't have anything to be proud of anymore so we don't.
Our shows of national pride are when we paint our faces during football word cups.
Oh boy, tons of that shit. It's not uncommon to see cars with WWII symbolics or stickers on them, pic related being an example.
It's also hilarious to see Civics with "TROPHY CAR" sticker on them.
