To me, this represents significantly more than just a "Heugh! That's pretty cool" moment. I think it represents a large - although not the first - step in the integration of the seemingly barely distantly related automotive and rocketry sectors.It looks like a spacecraft will be the first to use Tesla Plaid motors
"Direct drive using several Tesla Plaid motors in parallel for SN1. Simpler, lighter & more fault tolerant."
Elon Musk on Twitter
We already have had cross-pollination occur in the form of alloys developed at SpaceX becoming used in the Models X, CT and - I believe - 3, Y, and Semi. But to have motors as well make the jump - this should be considered yet another demonstration of the juggernaut that the Musk industrial universe is on its way to becoming.
