As the primary driver of our twosome, I spend my time in the passenger seat practising what in convents is called "custody of the eyes". I notice anything and everything that moves, but my depth perception is wonky when I'm on that side of the car -- I'm blind in one eye and, therefore, lack the slightest schmick of stereoscopic vision.

Himself says I'm hyper-vigilant, which makes perfect sense. I think hyper-vigilance is a rather useful trait, if not particularly restful.

For the record, I have been driving since 1975 and have precisely three impacts on my record: I backed into a bulkhead in a parking garage (above the roofline until the critical last nano-second) and a stanchion beside a historical marker in Flanders (below the bottom edge of the back window), and I sideswiped the barrier around a tight roundabout on my first day of driving a clunky Vauxhall on the British side of the road.

Himself notices all cats and dogs. I'm better at noticing wildlife than he is, especially birds. He notices two kinds of birds: cardinals, and all the other ones.
