A Skill may be divided into TWO or more Knowledges, like Driver is divided into ACV, Automotive, Grav, Legged, Mole, Tracked, and Wheeled. If so, you must choose your first two skill increases as Level 1 in two different Knowledges, or put both skill increases in a single Knowledge. Further skill increases go to Driving as a whole and improve all the Knowledge areas, since skill-levels stack as Skill+Knowledge, but there will always be 1 or 2 Knowledge areas greater than Driving skill-level alone. So if a player generates a character and gets Driving skill 4 times, they might end up with Driving-2 but Wheeled-3 and Grav-3; or Driving-2 and Grav-4.
