I know this is an old thread, but just to add to this something that was not mentioned, if you drive on Daytona with its steep banks with locked to horizon turned on, and you're in VR, the car will rotate to the left when it's on the banking, but your view will not. It will be as if the car is rotating 45 degrees around you as you sit in a chair that's on level ground. Not a pleasant feeling. So in this case, you'll want to turn it off so that you are sitting in the car, not floating in a car with the car rotating around you. Hope this helps someone.
