why don't we have 'i', but 'fi' instead?
I imagine it's because the sentence translates literally as "there is a car to me" or "car with me" so the pronoun is in the dative case (an indirect object).
why isn't "ddim" used here?
What instead of dim?
I imagine it may have something to do with things appearing after the subject getting mutated?
"Dw i ddim" has "dim" after the subject "i" and so turns into "ddim", but "does dim" has no subject and so "dim" stays "dim"?
Yeah that's correct.
what is fi. this is poorly explained
does i become fi? no explanation. very confusng
