So even tho this game doesn't technically have cross-progression, if you link your PSN account to the same Microsoft account you use for your gamertag, your Xbox/PC friends' Drivatars will appear. Also it looks like while my Playstation play through stats are reset, my records from my xbox account are still on theleaderboard (ie it says I discovered 399 roads but in game stats are much lower)
Also your favorited designs from your xbox/pc account will still appear in your favorites section on PS in the designs section as well which is clutch
