I don’t really know what I’ll do. I currently have to dual boot windows 10 for work since I do unreal game dev. I guess push for managers to allow me to setup a Linux dev env? But Linux binaries for third party plugins arent always there. That’s where I got stuck last time I tried.

Look up black hat cooperative! It’s vr but sounds pretty similar to what you after describing.

Purely theoretical as I don’t have any sources on how cars are doing this, but they could be communicating over low band networks similar to how Amazon home devices make a mesh network. Your car could send data to another car of the same manufacturer, who then phones home that data.
