So, I just got this game on PC. The second quest I got was to find "Slaky1980" and challenge him to a race. After the race I unlocked him as a Drivatar (whatever the F that is), which features a nice screenshot of a fully bearded Slaky. Also on the road I saw Bad Kermit driving around.
I'm pretty sure those two drivers are the Desipiots I remember. How they ended up in my game, I have no idea. Cheers all the same!
