well, um, I'm pretty sure the planes movies are in the same universe, and I think there were boats in one of them somewhere, so I think all vehi{les are?
in my opinion, um, the bigger question is how do things like hoofbeast-drawn {arriages work? are they alive? i-is the {riteria being a vehi{le, or having an engine?
I guess, I'm just working off the idea that within the movies, we see te{hnology advan{ing, whi{h implies that it must have advan{ed to some degree to get to the state it was in during the first movie
