This is an advanced civilization being modelled in Star Wars, not some rehistoric cave-man one. Frankly, that anyone at all is still going anywhere on foot is quite a leap of illogic. As civilization develops we continue to see things such as seques become more and more commonplace as well as scooters and hoverounds and all sorts of mobility devices becoming more in demand.
But, yet we have those who want to play without mounts, sprinting, running, and perhaps we even want to have their toons down on hands and knees or bellies crawling from one end of the planet to the other. Great for you! For my sub dollar, I'd rather spend more time killing and performing feats for missions not using my feet.
Everyone likes to play their own way.
