Passenger of Vehicles

I think it would be great if the player in the passenger seat of vehicles could rotate 360 deg. That way for example if you playing R. Hog Race the passenger can turn all the way around and fire at what’s behind him/her. I kind of find it annoying that the passenger can’t do this, the narrow field of vision makes this player almost useless unless he/she is carrying a flag or bomb. Anybody else liks this idea?
