“Auto” means “unaided; by itself.”
“Mobile” means “moves.”
So, an “auto-mobile” is something that moves by itself, right?
Well, actually, a car needs someone to drive and steer, so it isn’t really auto mobile.
But the Army is developing something that is. MULE (Multifunction Utility/Logistics and Equipment) runs completely on it/s own. And, as the video at the link shows, it can climb over obstacles up to five feet high.
Just the thing for getting out of traffic jams!
