They could use a fixed car address and use mobile IPv6 with a

That would help. A rendezvous point (e.g. home agent) always
helps to protect confidentiality. Plus a firewall to protect the
always-out-of-date vehicle software. They can work out how to do
path optimization later.
I agree. If you put the "home agent" in the middle of the internet
(for some value of middle), then path optimization probably isn't
that important.
Makes some sense. This "middle" depends on latency; and core network
has an order of magnitude (sometimes 2) less than even the first hop to
vehicle.
That means that it may suffice to put the HA on wired link, anywhere in
the Internet, and relatively close (in terms of hopcount) to where the
handover is about to take place. And not necessarily put it where eg
akamai stuff sits.
