I noticed, that in VR Mode with a Xbow the "hud map" is not shown, or only be shown if you turn your head to left. I use the HTC Vive.
I can confirm this. My default is map off but for this purpose I turned on the HUD map. Tested with the XBow on Laguna Seca and sometimes the track map pop ups when looking left and then disappears. BTW Xbow is also a joy to race around the tracks. Fun car and behaves very realistic.
