However, you do have to dribble when driving
Have you ever watched an NBA game? Those guys NEVER dribble when they attack the basket. Four, five steps and traveling is rarely called, particularly if you are a star whose 'move' involves walking with the ball. :)
I think you are looking for too close a match between reality and the game engine. DRIVING is more the ability to create your own shot. I say that because GMs have said it impacts jump shots. HANDLING seems to be used for turnover prevention, while PASSING is a skill that adds to the chance a teammate will make a shot.
