As with most things similar that come along, usually the sky is not falling. There will be some issues, I am sure, but I have read a lot of write ups on this thing from a lot of sources and I think people are over reacting. they should be concerned and question everything that comes out of government, but not go into a brain cramp. All I have ever been able to get from all I have read is this all centers around ECM's and software in them. Granted, these vehicles are becoming more like rolling computers, but there is a lot about them that has nothing to do with having to go in to the ECM or data bus in any way. I am not even convinced that folks will not be able to still plug into the OBD port and read a code.
