I noticed a similar thing when viewing a replay (Sierra), where I could change that view to reverse but not back. Ie. the release position of the button didn't work. All the other views continued to work as expected. But after restarting the game it was back to normal.When going into the pits (I only tried that online) using normal cockpit-camera, sometimes the in-car camera changes to looking back during the entire time you're in the pitlane.
I've never experienced that before.
