I always use first person, much more immersive. The only time I switch to third person is on bumpy roads because the screen shake is annoying. Would be good to have this an an option to turn off as well.
While I use third person view (which seems to be the default) I do find the automatic camera cycling when joining a start pen to be annoying. So every time I join an event early I have to set the camera back to third person.
And another thing, the emotes always default to elbow so you have to scroll down to ride-on every single ride (if you want to give out ride-on bombs).
It would be really nice if Zwift would simply remember your last selected camera and emote. Then there’d be no need to add anything to the user interface. It would just save it at the end of the ride (the same way it saves bike choice/rider kit/user personalisation).
