In this youtube video a hacker claims it is easily possible to mod the infotainment system in his Porsche to run the game Doom using the controls of his car to control the game.
This Gizmodo/Sploid story describes the supposed hack:
A YouTuber going by the name vexal uploaded this video tutorial showing what he claims to be a step-by-step guide to playing Doom on the console screen of a Porsche 911. That would be moderately interesting on its own but as he explains, the cars shifter, horn, accelerator and steering wheel all control the game—meaning you drive while you play.
According to his steps, take a flash drive that contains a single file with the car’s VIN number on it. Insert the drive into the Porsche’s USB slot and start the car. That should take the computer system into debug mode. Then, insert the game (he shows Doom II but says it works with the original as well) and select it on the console screen.
Even if possible this seems like a really insane idea. But the explanation seems simplistic to the point of unbelievability. He seems to claim, for example, that the game will just run once the car is in debug mode despite cars not usually running on Windows. Moreover, the controls on the car just work to control the game with no modifications or mapping to send control signals to the game.
Is it a spoof or is it real?
