Strangely enough, the only person I know that I would qualify as a "super tasker" is a Captain in the Army.
He could be talking to a General on the phone, drinking his coffee and driving in some of the worst traffic imaginable and it wasn't a problem at all. (traffic and rules of the road in South America make the worst traffic in the US look like a driver's ed training session)
One time a car came out of *no-where* and he reacted to it instantly before anyone else in the vehicle had even realized it was coming, avoided it, accelerated out of the situation and kept going, all the while not spilling a drop of coffee and not interrupting his conversation in the slightest.
I don't think I'd feel safe with *anyone else* I know doing that, but with this guy, he could pull it off.
