Cucumbers aren't native to England. They're not even native to Europe.
The English, get this, incorporated the exciting new vegetable into their diet after being introduced by Indians, and ignored whiny people telling the world "cucumbers aren't English" until they died out and we're forgotten by history. Imagine the 17th century version of yourself saying they'll burn down any teahouse that sells the exotic Indian "cucumber" because it's not English?
You can't expand your culture if you never try to expand it and "burn down" any change.
Imagine the bellend in 1650 that went "oh tea? I don't touch that Chinese stuff, never tried it and never will, and I'll burn down any establishment that sells it"
The bonus cringe is they could have simply driven into the spot instead of reversing in, which means the drivers side door (Australia) opens to the shrubs. I don't even drive and I know this.
