I have the usual concerns about privacy. I have no problem with someone
knowing the endpoint that is communicating is associated with a vehicle

someone can map easily from an IP address to a VIN (thus knowing the
specific vehicle from which the communication is happening), and I have
no choice but to reveal that information in order to communicate at all,
I am not comfortable. In general, as an architectural principle, I want
the option to control how much personal information I reveal. That's
called privacy.
Actual the problem is much simpler, it's not that easy to get the
unique ID of a vehicle today, however with the proposed solution it
become extremely easy.
In my experience the VIN is readily visible on most stationary vehicles
(by virtue of of of the locations being behind the windshield). using
it as a host address certainly implies that it's being broadcast more
widely.
Sort of the same idea that caused IPv6 to create all IPs based on the
mac address... we know how that ended, we created the privacy option.
Do we want todo it all over again?
