"Cars are driven in Paris."
Translation:Tiomáintear carranna i bPáras.

You say 'sa' if you are talking about something whose base includes 'an' (like an Fhrainc) or if you want to say 'in the' (like 'Tá an siosúr sa tarraiceán'). If you just want to say 'in,' you say 'i' + urú.
tl;dr: i = in, sa = in the
