One man’s quest to turn a video game into a real drive.

Toe in to a new car’s throttle, and you’re asking a computer to send air and fuel into the engine. Computers ­mediate braking and steering and almost always decide when the ­transmission should shift gears. Cars are evolving into video games.

So, why not make a video game into a car? Specifically, give a vintage-1986 Sega OutRun arcade game some wheels and a motor and let the gamer drive the concoction through physical space. Think of OutRun as Gran Turismo’s great-grandfather, fulfilling the preteen dream of ripping through various landscapes in an exotic car. Today, its roofless, eight-bit Ferrari Testarossa looks stone-ax primitive; in 1986, it was high-tech rad.

Sega eventually ported OutRun to home gaming systems, but it first appeared as an arcade game. Canadian-born academic Dr. ­Garnet Hertz, 38, saw one of  the old arcade versions in 2006. “That’s crazy, how large the cabinet is,” he recalls thinking. “It’s like a fake car.”  Two years later, he bought an OutRun arcade unit via an internet group for $300, then paid $800 to ship its 800 pounds to Irvine, California, where he started tinkering.

The electronics and the software required the most exhaustive development. Two high-def digital cameras mounted atop the cart feed images to a flat-screen display (it replaces OutRun’s original monitor) and to an Apple MacBook Pro, which uses its video feed to detect real-world topographical features. The computer then determines where to place the horizon (in the game’s primitive 3-D perspective, players constantly chase the road’s vanishing point in the distance) and how to depict the road. The gamer/driver sees the road ahead of him on-screen, rendered in OutRun graphics with the real world above the game’s horizon. Original game music pumps through speakers located in the headrest.
