This is the view I get when changing cameras after the cockpit view. It appears to still be from the cockpit but it like it streaming two separate views from the center like it's a 3d image.
The camera between cockpit and headcam is like a rollbar camera, usually up in the roof space or back seat somewhere. In your shot it looks like it happens to be fixed just in front of the mirror. Not sure why it's distorted, maybe to do with it being so close to the mirror. From memory it's a really wide angle by default, so that could be affecting the reflection too. edit: it's never really a useful driving view, it's more suited to replays
The mirror in that car is distorted however you view it. At least, it is in VR. The car right side seems to show a different angle from the rest of it.
then it should be entered in the bug reports section Bug Reports - Automobilista 2 (Read the Opening Post)
Go ahead if you think it's needed. I'm not really interested in trawling that thread to see if it's already been posted or not. It's so obvious that Reiza probably already know, but this is a beta... they have bigger things to fix first.
It looks great in replays on the open cockpit stuff, one problem is there is no way to lock the camera to this view in the replays.
The mirror is meant to be distorted, it gives you a wide angle view to the sides for seeing if someone is along side.
