One thing that could be done to make the andromeda hold many people and still MOVE would be to just use the andromeda interior objects and make a script for the Andromeda to move above the ground, then everyone could jump off from their. Just no one would be driving, not that a driver is needed with a mover script anyway.
also, doing this not only eliminates the jerkiness from lag, but it is also possible and no one would have to download a mod.
