The only ground vehicles I have seen are the Gallentean ground vehicles that are a commodity item. This leads me to believe that Caldari State and the Amarr Empire use, something else.
Hyperloops, trains, and moving sidewalks make a lot of sense on densely populated highly urbanized Caldari worlds.
Why no ground vehicles? Well, Caldari society is a militaristic fascist state. You don't go from point A to point B without proper authorization and clearance. If everyone travels by tube, there is an opportunity to check everyone's ID, inspect their itinerary, and scan them for contraband before and after they board.
Ground vehicles represent a certain degree of freedom, which is why the Gallente are so fond of using them and the Caldari heavily restrict their use.
I had actually imagined that the Amarrians would eschew motorized ground transportation completely, with the exception of trains and pneumatic tubes for slaves and cargo.
They would instead, still use animal mounts such as horses or giant two legged lizards for transportation. The reason for this? The Amarrians would argue that these animals are mentioned in scripture, and ground vehicles are not. In the stratified feudal heirarchy of Amarrian society, only the upper echelons of society (i.e. the 'Equestrians') would have the privilege of being able to ride mounts. Human slaves as rickshaw runners might also provide a taxi service in some cities.
