Politics ? Oh dear (or words to that affect)
So as 55012 is harmonised under the EMC directive you could in theory meet that directive but fail the automotive directive.

No: their scopes are, or should be, mutually exclusive. The point is that 2 dB isn't going to make the difference between a product that is safe to use in a car and one that isn't, especially as production units could vary by more than 2 dB when installed (e.g. due to different wiring). So there really seems no technical reason for the difference, but different people and different committees prepared the documents.
