The "Dealership" QC model isn't my favorite, but it sounds way better than today's model (zip, unless you pass by Mitsubishi with a low SOC). Not sure the dealers will want to write an invoice and send you to the cashier for a $7 fee, but if Nissan can pressure their dealers into offering this, I'd use it. Nissan dealers are usually next to freeways (Cerritos, Monrovia, and Thousand Oaks pop to mind, plus Fontana), making them ideal, easy-to-spot en route stations. They have restrooms, vending machines, and usually a TV, and are secure. Downsides: not 24/7, they won't get them in all dealerships, and history suggests Nissan will never be able to enforce consistent pricing, hours, or access the way we customers would like (how does McDonalds make fries come out the same in 4,000 restaurants, but Nissan can't make 10 dealers offer consistent L2 access??).
I'd prefer imperfect QC's to non-existent ones.
