I agree with you when we classify edge-site scenarios.   Also we need to
understand applicability of edge computing use case (not NFV use case we
already know) at each type of edge-site.

According to the following 5G Automotive Association’s WP(p11),  “A typical
challenge in IoV is the big data processing and storage resulting from a
huge and growing number of sensors in smart/connected vehicles and roads.
This, in turn, requires new services platforms with powerful processing and
computing resources, low cost and trusted storage, and real-time
communication capabilities. MEC appears as a promising opportunity to
migrate Cloud resources closer to the vehicles and the data sources and
hence save network resources and reduce the latency. “


How can OpenStack Edge Computing help Automotive industry?
