I'd like to propose an object that can be attached to a vehicle like any other part, the only purpose of which is to be the perspective source for a first-person camera.  IE, you hit a button and now your view is locked to where the object is, facing the direction it is facing, and will move as the object/vehicle moves until you hit the button again to return to the default view.

This object could be in several different forms:

A port-hole / eye-shaped decoration, attached to flat surfaces (like you would an armor plate)
A Spy-Glass, mounted exactly as you would a cannon.
Or even a "passenger", a little man you can have standing or sitting on/in your vehicle (also serving as an amusing decoration / launchable, even if you don't use the first-person-view feature)


Specific benefits to such an object would include:

Making a 'bumper cam' for precision driving (or front-row seat for vehicular manslaughter)
Mounting next to cannons or other launchers, for accurate aiming.
Attaching to the bottom of a flier, as a bombing-cam
Putting on the end of a swinging weapon or launching out of a catapult in slow-motion, just to enjoy the view.


I hope this isn't too much to ask, as I feel many users would enjoy the feel of being on or in their siege-engines.
