I thought the new 3/Y cameras reduced the glare when using the turn signals at night. If true, it likely has nothing to do with FSD directly. I certainly would not reject a new order as a result, particularly if there is a financial penalty. Worst case and they have a feature you MUST have, get your wallet out and do a retrofit - it's easy enough and likely not that expensive. I too was once a new buyer of my very expensive vehicle and wanted everything to be perfect - but today, MEH.
But as many others have pointed out, we just don't know.
