I like to ride with the #3 camera view which is kind of like a POV when riding in a bunch. But to check behind I have to change the camera view and then change back.
It would be cool to have the option to have second camera view in a small pain. For racing this would be great because being able to be facing forward but also be able to take quick glance back to see if anyone is coming up would be much more realistic than having to change the camera view with it animations and then change back.
