Logic

[Crushnight]

Because wheeled vehicles already exists. They're just not known by the term "car".

You also have to consider when you can do this event which is right after 2.0 story has been done where the most technological advanced thing was ultima weapon which was a primal slaying monstrously sized mech, this car is then the next most advanced thing and its purely ironworks creation after cid looks and probably reversed engineered blueprints when working on fixing ffxv's version.

@Malzian ofc many things aren't canon within the contents of the story but within this collaberation's own story a car doesn't make us bat an eye but we have no idea what a photograph is and can actually question it, this is where i see the logic fault :P
