LOL, that's funny.
But, considering it's a redundant feature ina redundant vehicle, it makes sense as well.

In the world of horribly redundant superhero vehicles, the Supermobile reigns supreme!
And I suppose, among the vast science and technological resources that Superman would have at his disposal, a super vehicle of some kind makes sense.
My favorite aspect of the Supermobile is the Super-visor, a binocular like apparatus that rises from the dashboard, with a dial allowing Superman the option of x-ray, telescopic, infrared, and normal vision. Normal vision? Why is there a setting for normal vision? If he wanted normal vision, all he'd have to do is move his head to the side three inches.
