As above - it seems fairly superfluous!
Of course, that above sentence is too short... So I'll add this bit to make it pass the automated check...
I agree it is superfluous :D (I love that word).
I believe this should be deleted with the intent to move the questions associated with it to other tags which make more sense. I mean, if it was car identification it wouldn't fall directly under "car" ... it's an ID question, tag it as such. Anything else is plain idiotic to me.
There are other offenders (stats as of today):
58 x car questions
32 x truck questions
2 x pick-up questions (this gem's tagged with all three!)
268 x motorcycle questions
I can understand why folks might tag a question as motorcycle, but I'm not entirely convinced it is useful when the make and model are clearly specified.
