Heard from my DS. Confirms P85D December deliveries will have old model seats. Change out planned for January, when new seats available. Tesla did not want to hold up deliveries to install seats. I expect this has a lot to do with meeting year-end product goal.
All safety function hardware installed. Only radar and lane following software activated. Remainder will be activated over the air when cleared testing. Car should have shipped yesterday (Monday). Transportation time based on one or two drivers in the truck. Two drivers can get to Florida in approximately 4 days with no weather or other limitations. One driver requires 7-10 days to make the transit.
