A large map means nothing if the areas are not diverse and full of content. If the FFXV map is as rich as some of the other games that have been mentioned, then it will be very fun to explore. However, if it is a lot of open road you just drive through then there's not much point to it.

Just going by the information shown here, it is very impressive how much bigger FFXV is compared to some other popular open world games!

Also I know the car has been shown a lot for this game, but will we get to fly through this vast world too? I recall airships being one of the last things they are trying to create and that they are not guaranteed, but I hope fast travel (Xenoblade-style free and easy travel please) or some kind of free-flying approach is available.
