Drive-In Movie Theater in contradiction with FAQ about carring vehicles?

[Cammagno]

This dungeon from Scooby-Doo states that all vehicles, also if "only-carried" and even if the player can't normally use them, get an additional +3 bonus.

I was under the impression, according to this FAQ , that a vehicle could not be only carried as not equipped, and that if it could not be used must be get rid of.

So, is this a mistake in the card, a change in the general guideline requiring an update of the FAQ, or simply the general rule is overwritten in this Dungeon, and here (and only here) the players can carry unequipped vehicles?
If this is the case, does this mean that in this dungeon those unequipped vehicles also grant their normal combat bonus (if any), or only the +3?

The Rules of Scooby Doo state that vehicles carry themselves and that you can only have one. The only sense I can make of this Dungeon is that it is allowing you +3 for each vehicle that is still in your hand. Otherwise, I do not understand how you could be "carrying" one.

Note that the Bad Stuff of another Scooby-Doo card, Witch, is
Lose all equipped Vehicle cards

I think this need some clarification too

The rules state that some cards might allow you to equip more than one vehicle, and you could always Cheat one. This is different from the Drive-In stating you could possibly be carrying some.

Right, I agree with you
