Cables are short, but the EM environment is harsh, and magnetics
(transformers) give quite a lot of up-front assurance that immunity will
be high.

I continue to look into questions on ethernet magnetics.
For automotive applications, are magentics required if all nodes are
within short distances and within a single vehicle?
I always understood magnetics to be required for long cable runs and
nodes at different ground references. The automotive vehicle is an
exception to those two in that cable runs are not 100m, and all
nodes share a common reference.
Thanks in advance.
Patrick.
