Tesla has doubled their production over the past year. They are now producing 1,000 cars a day. To do this they have resolved lots of issues with vehicle production.
Now that volume has moved to delivering 1,000 vehicles a day. New bottle necks will show up up paperwork, payments, change orders, scratches, finish blemishes etc. Will take a lot of people to handle the volume and address the problems. Elon has stated that they want excellent employees, but they are not easy to find.
Just think of how difficult it would be to charge 1,000 cars a day. Some are going to go out the door without a full charge. It is not good to fully 100% charge the batteries and let them sit for a long time. Probably best would be to charge them to around 80%, however the moment you unplug them that charge will slowly decrease due to vampire drain.
Last car I bought had a extra charge on the Moronie sticker with a $35 charge for 10 gallons of gas. At least Tesla does not charge for your your first charge..
You really only need enough charge to get you to a local Supercharger, where you can "test" out your charging system and get used to the process.
I understand that everyone wants a perfect car, but no car is perfect. You just need to see if the car is acceptable to you. If it is, then accept delivery. If not reject the car.
Tesla is aware of the situation, and is instituting new policies to address them. New delivery centers are being opened all around the world. Some local deliveries are now being done at the customers home or place of business to reduce the handling and storage that can add to the smudges. You might even get your car hand delivered by Elon himself. He is on the line right now, rolling up his sleeves and seeing the delivery protocol for himself.
I expect Tesla to get a hand on delivering this volume of cars in short order.
In the future, I see a day when the car will drive itself from the end of the assembly line directly to the customers chosen location via Autopilot. Customer will inspect the car and type in a PIN to acknowledge delivery or another PIN to sent it back for issues.
