I was involved in a Nissan advertisement project connecting Playstation 4 with a cars as controllers[1]. They did a convention tour with 4 cars playing the same football game in front of a projector.

I did everything except front end and CAN interface though, $20 USB CAN reader device + python. I remember it took a while for my colleague to figure out the right input signals as the bus was quite chatty/high output, like tailing android logcat on verbose. We didn't use any factory unlock codes or anything to get more data.

As a gamer it was not really up to par - big deadzone when turning the wheel from one side to the other as we did not have time to get analogue movement read correctly.

On that particular car model you had to interact with the touch display every 15 minutes or else the whole car went into power saving mode and the CAN bus stopped sending messages.

I recommend the SCRAFT channel if you want to see 3D printed mechanics: https://www.youtube.com/@SCRAFTchannel/featured

Usually they are connected to a electric motor and different speeds are tested. Some mechanics get a nice sound.

No the SteamVR tracking system used by Valve Index, HTC Vive, Pimax and some headsets with extra tracking-plates use IR photo-diodes:

VR users that want full body tracking usually go with outside-in tracking, with tracking devices strapped to their bodies. It is expensive, but the accuracy is very good.
