"She’s got character." Xavi leaned against the battered side of the van as the sun set behind him. The vehicle had been gray when dinosaurs ruled the Earth; now it was a jigsaw of different parts. The body was boxy, small engine in the front, driver and passengers seats crammed into a tiny cabin, then cargo space behind. The passenger’s door was green, the driver’s red, and brown twine tied in a scruffy knot held the rear doors together. Its engine belched blue smoke as it chattered to itself, the beat irregular. The only concession to modernity was the LIDAR array epoxied to the roof alongside a semicircle of bulbous lenses—an old autonomous driving system jerry-rigged to the vehicle. A blue cable snaked from the array to enter the cabin via the driver’s window.
