I mean its reported tesla are looking around for alternate press suppliers and people in the industry have also commented that trying to make a casting that big is pretty ambitious and a 60% scrap rate is not unexpected.
People have also calculated deliveries of gigapress cars to confirm the scrap rate so its not BS.
Then there is the issue of the casting cracking in an accident which can potentially write off a car that would have been repairable with traditional spot welded designs, this will increase insurance rates for Teslas long term.
So it remains to be see if its a genius move from Musk, or if traditional spot welded designs are in fact the better approach.
