The modder’s name is Stan Dmitriev, and he is the CMO and co-founder of SurrogateTV. According to his Twitter bio, he’s into robotics, chess, and esports. He is also a talented SBC enthusiast, as his latest project demonstrates once again.

Dmitriev also worked a GoPro and capture card into his project, though notes users can employ a Raspberry Pi camera module or webcam instead.
“The setup runs via a website called Surrogate.tv and uses its open-source Python SDK. There’s a premade game template for an RC Car setup, so you don’t even need to code to replicate the setup,” Dmitriev explains.
What is especially neat about this mod is being able to control the RC car through the web, with a pretty fast response time. According to Dmitriev, there is about a 200ms delay. That might be disastrous for gaming, but as he demonstrates in the video, it works really well with the RC car, which he can drive back and forth, and change direction, all while seeing a feed captured with the GoPro mounted on top.
This is something you could replicate yourself, if you are so inclined. Dmitriev posted a guide (embedded above), complete with links to various documentation and an SD card image to make it as easy as possible. If you do attempt this, he recommends using a 4×4 jeep or something similar, with a 1:16 scale being ideal for this project. That way it can go over different terrain without getting stuck.
As one of the commenters alluded to, this same mod could be applied to an RC boat, for some fun RC boat racing—no need to stick to land, if you don’t want to. Either way, this is a really neat mod.
