Well, I do know my ADD helps me at least. I remember when my mom wanted to put me on meds again, I could barely drive. I had to force myself to stop paying attention to one thing at a time, like tearing away my gaze or something. Without the meds, I can easily "zone out" while driving and still be perfectly safe...and I won't feel like I'm on the road as much.
Course, there's the downside, sometimes ADD gets you staring at one thing a little too intently, like billboards, haha. But that's not that often.
