A comment on Tesla Transport Protocol over Ethernet (TTPoE). Parent comment
Random guessing - Ethercat seems more likely to take over for CAN because CoE (canopen over ethercat) is so common.
It's very easy to turn CAN devices into ethercat ones.
Harder to turn them into profinet ones.
Seems like a more incremental path for car makers.
otherwise the main advantage of profinet is that you can treat it like regular ethernet (IE switches, etc), but not sure anyone cares in a car.
