Doubt about the etymology of the word "car"

I was watching the anime "Orbe: About the movements of the earth" and the protagonist quoted a popular saying "you don't put the cart before the horse", but pay attention because he said "car" and when I think about car I think about vehicles powered by combustion and not by carts, which was what existed at that time(middle ages), my question is whether the term car was really used at that time or was this just a nomenclature error in the caption(in my opinion, the saying goes wrong, well with the time, but the term no), I have a video showing it, but the subreddit won't let me send it🥹
