You know what I want to see more of?
Intra-planetary travel in Star Trek.
How did Vulcans travel cross-planet? Car type vehicles? Trains? Did they walk? If so, why?
Bajorans are hella art-nouveau. Would they have subway systems reflecting that aesthetic? Would some in large cities have been caved in to save the architecture from Cardassian modification/destruction?
There’s more to moving people than spaceships
