TBH, the repairability concerns seem to be overstated so far. There are still conventional crash structures in front of and behind them. It takes a lot to damage the casting beyond repair.

You are right, though. The jury is still out in that they haven't really been used in the real world for long.

> Audi did in 2016 with the SQ7 TDI, no?

I didn't know about that one, but it was still a dual architecture. Going full 48V is a bit different, assuming Tesla really did that.
