You are absolutely at the right place. We have gone to extra length to design our code so that vehicle specifics are abstracted away behind interfaces. Also things are easily switchable. For example, don't like our physics engine, bring your own! As mentioned in release notes, we are working on other vehicle types. However water based crafts are not on our radar. My guess would be that physics would be more expensive and less accurate in general for water based vehicles.
