Let’s see...The area of New Mexico is about 2000 square miles so if the optimistic figures work out in the field all that is needed is just one state covered with machines! Easy!

"Let’s see...The area of New Mexico is about 2000 square miles"

You really ought to check your facts more closely:

New Mexico Land area: 121,356 sq mi

2000 square miles is only a rectangle 40 miles by 50 miles, which is a postage stamp compared to most states (except for perhaps Rhode Island). Even Massachusetts is around 8000 square miles.
