Is there a bus protocol similar to CAN bus except with ethernet sized frames?

• Not point to point like SLIP, but a multi-device bus.
  
  In the olden days there was 10base2 over coax but that disappeared long ago. Is there a modern equivalent?

• Well, there is CAN FD, which can have 64 bytes of payload data per message, but that is only equivalent to the least amount of data an ethernet frame can carry.

• RS-485 with your own protocol / packetisation?

• There's nothing stopping you from using CAN (or RS-485) physical layer components and writing your own ethernet-like protocol. Whether the amount of work required is justified here I leave to you to decide.

• Flexray is somewhere in the middle. 254 byte payload, looks to be time triggered instead of CSMA, ~10Mbps.
