"Conclusion
So which interface is best for automotive communications? They all are—but each for its own purpose. The CAN bus reigns supreme for low-speed control applications where cost is a driving factor. When bandwidth requirements move up, Ethernet can step in as an enhanced interface to support moderate bandwidth requirements. When the
highest bandwidth and lowest-latency link are required, such as for a surround-view camera system providing input to an autonomous vehicle pilot, then FPD-Link is ready to meet the challenge."
