"…the #Cybertruck cranks things up a notch, with a radically new wiring harness that Tesla calls #Etherloop. This consists of a single continuous gigabit Ethernet cable that loops around the interior of the Cybertruck. Remember #TokenRing? It connects to 368 endpoints & reduces cross-vehicle wiring by 68%. Data is time-sliced and latency is just 0.5ms. If the loop is cut, data goes other way around."
