No, not the plate with the numbers and letters on it, nor the little plastic card with your picture and birthdate on it, this is something completely different. For some of you (perhaps many of you) this will raise your hackles. Some auto makers are arguing that the electronica in the cars they produce are covered by the DMCA, that the buyers of their products should not be allowed to do any kind of work on those vehicles because they are copyrighted. They are arguing that they, the manufacturers should by IP law even be empowered to deny their customers the right to go to any mechanic who has not been approved by them. Do they have a leg to stand on? Should they?
