Roadster owners can download raw logs straight from their cars.[1] For Model S/X, you need a proprietary device to connect to the car's ethernet port (it may be possible to build your own -- not sure if they are encrypted), or you need Tesla to download them and hand them over. Tesla has told me that they will only release logs when ordered to do so by a court, but that they will download and hold them locally upon an owner's request, so that if you think you will have a legal need for them you have time to make that request before they get pruned/deleted by the car.
