There has been a lot of work developing standards for reliable ethernet for industrial and automotive applications, resolving most of the issues you mention which apply to 100/1000Base-T. Tesla isn't using your garden variety ethernet or abominations like ethercat.
100/1000Base-T1 is intended to be used with PoDL (802.3bg/cu) and TSN (various 802.1Q)to result in reliable links with guaranteed latency and bandwidth properties.
PHY power is a few hundred mw though, and star topologies are limiting to replace CAN/LIN nodes, that's what 10Base-T1S is for though (cheaper, bussed, lower power).
