Hey! When did this topic turn to people with ADD?
Ok, anyways, I have ADHD, which is close enough, and I'm learning to drive now, and I can drive a stick shift (somewhat), but I just perfer to drive a manual. I don't think it makes you more aware of anything - it becomes second nature when you're shifting and you don't even have to pay attention to doing it.
But getting back to my point - I've driven both a manual and an automatic and I have no no problems, even for a kid with ADHD.
