TCP has the wrong abstraction for truly high performance.
I wouldn't necessarily standardize what Tesla does here, but most of the big companies have their own layer 3 transport protocol for things that need truly high speed and are operating within a datacenter.
Cray/HPE has their own Ethernet-based protocol (Slingshot was an earlier version of it - not sure what its name is now) which seems to be better than whatever Tesla has, but is not necessarily published.

RoCE sends huge packets down the wire.
