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.
