There's orders of magnitude different in having to walk up to the
windshield of every car you're interested in vs. passively sniffing IP
traffic to discover VINs of thousands of cars in a go.
And dare I mention the big brother aspect of setting up roadside
monitors? And what about son-of-google-street-view? The privacy aspects
of being able to reverse-map IP traffic to VINs are staggering.
It is relatively costly today to set a distributed monitoring
infrastructure that tracks the comings and goings of automobiles (and by
proxy their owners) (think city of london or stockholm) and the use of
and access to such datasets is generally restricted and subject to
strong privacy protections). it should not be the case that we trivially
enable such data-gathering.
I remain unconvinced that there should be any special case in the
protocol for this, as I've yet to see an argument as to why ULAs are not
sufficient. I remain violently opposed to any protocol definition that
supports VIN <> IP address mapping.
