Car dealerships, museums, garages ... several reasons for why a car would be indoors
"Látok bent autókat." (I switched the word order because this is the neutral one. The original one emphisises "bent".
Where I come from, we don't use that word for car. It would be an "automobile." And anyway, I think that's a different word.
I don't know of any dialect of English where a car is called "an auto".
This sentence would be much easier if it were more realistic like 'I see a car outside' or I see a boy inside
A semantically unrealistic sentence can test how much we are relying on real world knowledge instead of knowledge of the language.
