A few cars just like this park in an underground commercial garage near where live. I see them coming and going at all hours. Sometimes I notice them cruising around town, curious appendages (cameras?) sticking out of their grills or jutting above their rooflines. They have drivers -- or maybe those are failsafe passengers in a fingers-crossed-self-driving vehicle? Anyway, walking to fetch the mail tonight, I observed what might've been a changing of the guard. Or guinea pig.
A guy gets out of the car as another guy walks up.
"How'd it go out there, Donnie?" the walking-up guy says.
"All right," says Donnie. "It's going all right." He stretches out the last two vowels like he's somehow living large: Aaaaall riiiight.
And with that (not much!), Donnie walks off into the early evening. The second guy takes the wheel. Or at least gets into the car. Or at least sits in the thing that resembles a car, but might actually be some top-secret contraption performing unspeakable experiments on local streets.
