Tired of the indignities of riding public shuttles? Don't want to pay a smuggler's exorbitant fees? Try flying yourself! These days, shuttle controls are so simple that even untrained (read: non-pilot) users can putter about their local system.
And for the low, low cost of one astromech droid with hyperspace capabilities (an R2 or better), the Galaxy can be your oyster. No one to tell you "no," and no planet, space station, or asteroid you cannot reach.
