I don't know why but it made me think of the original premise of Drivatars in Forza games - Microsoft selling it as an "AI" learning how you drive, then your individual driveatar would be submitted to Xbox Live and would randomly appear for other players in their offline games, but it would drive just like you drive. Really cool concept, of that "footprint" of your play appearing in other people's games.

Shame that it just languished to a point where I think Microsoft completely lost both interest and control over that feature, where in Horizon 6 it just gives you the exact same few driveatars every race, and somehow no one at Playground Games is interested in fixing this. At this point I strongly suspect that they literally don't know how to, the knowledge is lost in the depths of the netcode.
