Went to the Tesla store in Lynnwood, WA today. Currently they have no display cars and no test drive cars. All the new cars on the lot were for delivery to customers. Asked about what were the latest features he was seeing on new cars. He said he was expecting to see new cars with a new auxiliary battery, and new AMD chip, but it sounded like he had not seen them yet. Asked about rear windows being doubled glazed like the front windows, but he did not seem to know anything about this new feature. So not a lot of useful information gathered, posting this just as another data point.
