I think if it was obvious it would already be on the market. To me reaching out of your car because you drove to far away from the ATM is a problem. It makes it inconvient for people to use drive up solutions. If the peices are extended out problem solved. Is it obvious? Again Drive up ATMs have been around for a decade not one does it this way. After I point it out sure it seems obvious, but almost all patents are that way.
