Volkswagen issued DMCA takedown notices three times on drawings of beetles. Insects, that is. It took a lawyer's letter to get the matter corrected — that's how unfair the DMCA takedown system is, in practice.

IANAL, but I don't think it would have changed matters if they were drawings of Volkswagen cars. As I understand it, there is no US copyright on the shape of a car (it is not a sculpture), so Volkswagen would have no copyright grounds to object to someone else's drawing or photo of those cars.

The DMCA applies to copyright law and only copyright law, not to the bogus category of "intellectual property" which does not correspond to real laws. If you use that term in your thoughts (or worse, your words), it is confusing you.
