Picture this scenario: You and a friend are walking around your neighborhood when you stop at a crosswalk. As you wait, the noises of the world and your internal thoughts all vie for your attention. Suddenly, you see a motorist nearly hit a bicyclist.

“Whoa, did you see that?” you say to your friend.

“I sure did; that was a fully restored 1967 Ford Mustang,” your friend replies, referring to a car separate from the near-traffic collision.
