"They are taking the cars."
Translation:Az autókat viszik.
Well, no need for things to get heated...
Non-gender-specific, third person singular in English is "they" (Gender-specific: "he" and "she")
Third person plural - also "they"
I /always/ use they to mean a single person whenever the gender is either irrelevant or inappropriate.
I'm not sure why people would get heated over it... Singular they has been in existence and use for a loooooooooong time.
