PoE over CAN bus moves more complexity from EE world into software world. While Tesla currently has best auto software, this is still a very foreign and a different way of thinking/managing for traditional auto manufacturing. This won't be just using a different set of cables, it's going to flip their engineering departments upside down.

Wouldn’t it be PoC instead of PoE?

Power over Ethernet (PoE) is a technique for delivering DC power to devices over copper Ethernet cabling, eliminating the need for separate power supplies and outlets.

Yes, but afaik CAN is not usually done over Ethernet
