I noticed there are only elevator mods for vertical transit but none for any horizontal movement.

I believe this is because (prior to the ladder), vertical mouvement in the game was a pain to do, either taking too much space with stairs or require a jetpack.

As far as I can tell it’s because elevators are just pistons with specific parameters to follow. I’m wondering if it’s possible to do something similar for horizontal movement.

It would be possible, it's just a matter of modeling a 'piston' as an horizontal elevator. But really just walk that distance, it's faster... (except special niche case)

引用自 BrainJax：

Piston pushes an elevator to its designated floor, releases the elevator while a horizontal piston grabs onto it and moves it horizontally.

Sound like you have your non modded version sorted out, you just need to implement it, also you may want the horizontal pistons to grab the cabin before the vertical one release it.
It's just a matter of magnetic plates or landing gears, detached small grid cabin, and pistons, and a good script or well designed timer blocks and event controllers.

VCZ Multifloor elevator does a really good job making a vertical elevator system look seamless. I’m looking for something similar.

I am not aware of any horizontal ones either, as I said, usually walking is faster (unless niche case). But you could ask for the modders if they are willing to implement it.

I suspect that any attempt to implement this in the current game engine will only end in spectacular destruction.

You are correct. And frankly, it’s pretty useless to implement it vanilla anyway. The distance it would be able to travel horizontally is pretty short. VCZ multifloor elevator somehow found a way to change the max distance the “piston” can push the elevator from how far a piston can extend to how many floors the elevator shaft has (max 9). Something similar would have to be implemented to make horizontal transit useful over just getting out and walking.

A literal turbolift (from star trek) is in the star trek mod pack by quarrania. It is technically a teleporter so there's no literal movement but I think it can teleport to any one of the turbolifts on your grid.
