My wife can read upside down. And she can see round corners, and has eyes in the back of her head.
But, I'll give you this, she can make very dumb navigational errors. But, she's much better at packing the boot (trunk) than I am, when there's a lot of stuff to fit in.
And, she is a good driver. Although, she did ram a stationary stump in a carpark once, hard, and remodelled the front of the car.
