Ok, I didn't know. The joke really isn't that creative, so not surprised someone else also thought of it. I think you should maybe keep that in mind next time you accuse someone of plagiarism.
Edit: I was actually being serious. I guess I'm more gullible today than usual. Now that I re-watch it and read the comments it is very clearly a joke.
This is mentioned in the comments on youtube as well. The reply from author is "That's because there was a half-second near the end in my driveway where the thinning of my hair was much more visible than I was comfortable with, so I edited that part out."
I feel like Occam's razor applies here in a non-intuitive way.
Either he:
1. Recorded a video of him driving a car and frantically pressing the horn
2. Made a screen capture of Doom that matches the gun fire, turns, and weapon changes perfectly to his car video
3. Did some video editing to superimpose the video including several cases where his thumb goes over the screen while shifting
Or....
1. He put software on the car console (which is pretty much a full computer)
2. He actually mapped the controls to data being read from the onboard computer
I mean, I couldn't do this... one I don't know how to write software for a Porsche console and two I can't afford a Porsche :-P but faking it seems like way more work and worse ROI than actually doing it.
Edit: alternatively in some cars the console actually takes RGB or HDMI input and you don't even need to run directly on the console assuming ODB-II has enough info to read the input signals. I can totally see myself doing this if I had the time. Seems fun (albeit a bit dangerous for my taste)
Edit 2: It could still be a fake but it's not unreasonable to think it isn't.
It might very well be my experience bias. As someone who is good at software engineering and bad at video editing, to me actually making it work seems more interesting and doable.
If you follow along at 0.25 speed one can tell that the screen is moving slightly in a non-linear fashion while the car is just beginning to move. Also the screen mysteriously does not experience any motion blur, though the rest of the car does.
He didn't bother to do the extra work required (in After Effects) to progressively superpose the seat over the screen in a credible manner. Video edition is much more time consuming when moving objects get in front of the faked screen.
This sits right at the intersection of insane and awesome.
Note the WASD controls are replaced by the throttle, brakes and steering wheel. The horn is for shooting the gun, and the gearbox controls the currently selected gun.
