My dad has an amazing ability to ignore what's going on around him.
sometimes this comes across as being focused, but when he's behind the wheel it comes across as being scary. it doesn't matter that they live outside of washington DC and that no one ever drives the speed limit. My dad will drive down the beltway, 10 miles below the speed limit with cars zooming past on both sides. His eyesight isn't the greatest, as he seems to have to squint at everything. he'll be in his own little world, driving and smiling and pointing out things as if everyone else in the car is seeing the world for the first time.

Dad: "man, look at all these cars."

Imagine that, cars on the highway, all of which I'm surprised haven't rear ended us.

Dad: "i used to work in that building over yonder"

In fact he did, and i lived under his roof for many a year when he did in fact work in that bulding over yonder. I remember it like it was just last year, maybe becuase it was just in fact last year when he stopped working there.

dad: "woooo-weee! Did you see the tits on that girl!"

Oh not this again. Well maybe his eyesight isn't that bad after all.
