Boats or Trains

I’ve often thought of what would be the next mode of transportation would be after the devs felt like they’ve done all they can in the automobile portion of the game. Would you all prefer trains or boats

Trains: train engines are just huge car engines, they go on tracks so their is less worry about unpredictably, maps can easily implement tracks (west coast map already has trolley tracks) having a train route to haul people, materials and cars in career mode would be awesome as well as scenarios.

Boats: engines are just smaller car engines, some boats even have V8’s found in Chevy’s, they tend to be slower so it wouldn’t need to be a huge map compared to implementing planes but the downside is maps don’t have many boating harbors or ports. Putting boating jobs or races would be cool

Not to gloss over the progress or success of what they have done so far. Just curious as to what would be preferred
