Completely agree!!! All of this breathless holding, cancelling, removing holds, unmatching VINs is a bunch of nonsense.
Everybody's situation is different and unique and cannot be dismissed as nonsense. Tesla has a reason for allowing config changes and holds since it provides maximum flexibility to the customer.
The current deviation in EDD windows cannot be attributed to holds mainly. Given the supply chain issues (Tesla is handling this well compared to other companies but is not immune to it) and given that Covid is affecting Tesla's and other suppliers' employees , fluctuations in EDD's are expected.
