That's a rather bold assertion. I have yet to see any evidence of VIN skipping. Do you have any evidence? There are times when VINs are seemingly "skipped" because they do a run of inventory cars, but we end up seeing these VINs for sale in inventory, and the cars are ultimately sold and the VINs are in circulation. If you have evidence of large numbers of VINs that vanished into thin air I'd be very interested to see them. Tesla batches builds, not VINs - VINs are issued (more or less) sequentially and then the build order can be based on a number of factors. Again, no evidence I'm aware of that VINs are held back or batched, but I'd love to see it if you have it.
Where's the evidence VINs were skipped for AP2.0? There's no way to tell yet. Whatever numbers you think may have been skipped could very well show up in US or overseas inventory in the next 2 months. There's also plenty of entries in the S order tracker to show the VIN trend and there's no solid evidence of VIN skipping. Here's a sampling of recent VIN assignment dates and VINs:
9/26 - 164,xxx
10/4 - 166,2xx
10/11 - 167,745
10/17 - 169,xxx
10/18 - 170,xxx
10/19 - AP 2.0 ANNOUNCED
10/23 - 170,xxx
10/26 - 170,xxx
10/27 - 171,xxx
That looks like a steady, strong trend to me. Where's the skipped VINs?
