The hand wash down the street will clean your car, but they just can't completely sanitize it like a rocket car can. How, you ask? Simple. It douses it in pure, organically-raised flames. All of the exposed surfaces are bathed in purifying waves of light and fire. The end result? The world's cleanest car.
On a side note, we're probably a bit away from a "sit in your car" version of this car wash.
