On top of the racing updates that will be coming in 3.20, the community has created a series of race tracks in the PU. XGR made some really cool interactive maps of them in 3D and posted them on SketchFab!

Some of these are official tracks in the PU, while others are XGRs competition tracks:

The Snake Pit - PU Track

Yadar Valley - PU Track

The Icebreaker - PU Track

Beautiful Glen Circuit - XGR Track

Baijini Blitz - XGR Track
