Like you, I find the 30 million lines in the EMS to be very unlikely.

Now if you add in the entertainment systems and other dashboard
display and control systems, it might get a bit closer.

Tesla's and other vehicles with partial or full self-driving capabilities
are a different story, with incredibly complicated and large SoC's
with several different grades of processor, safety islands and
redundancy.
