As big a pain as it is, yes, the one on the right is a subpanel, and subject to all of the rules thereof.
Around here the service wires between the two would be 2 2/0, 1 1/0, and a #6 green. I can't believe they used a tamper resistant screw on a deadfront cover...dumb, and possibly dangerous.

Hi,
The panel with the breakers could have been wired at the factory as a main service and be bonded inside. Sounds like it, since the service grounding conductor comes from the panel with the breakers.
Maybe nobody thought to ask about what side the service lateral was coming in on, so the utility put in the service lateral with a main disconnect where they thought it would be the most convenient for them.
It's my understanding though that equipment grounding conductors and grounded conductors are supposed to be separated past the main disconnect and that the service ground is supposed to be at the main disconnect. If that is the case, shouldn't any bonding strap or screws have been removed and the service grounding conductor moved to the main disconnect and then the main disconnect bonded and the service grounding conductor connected to a driven service grounding electrode?
The other thing is the "twisted" connection between a ufer cable and the service grounding conductor. This is the one cable that can't be spliced, so a new cable, long enough to reach the ufer, should have been installed.
That's my story and I'm sticking to it 'cuz electricity is my weakest area and I don't know any better. 
ONE TEAM - ONE FIGHT!!!
Mike

Thanks for the quick response guys. Thats what I thought also.
Brian, you know your sparkie stuff. thanks bro.
Mike, I think you are right about using the main panel as the sub because of a blank in the normal hole for the meter. It sure looks bonded to me! DOAH  d]
About 3 feet from the bottom of this panel is a bollard-less gas regulator in the driveway. NICE .... (notice: no sleeve around the plastic line where it emerges from the driveway) SHEEESH!
I have included photos
