It's not clear DMCA applies in this setting. I'm neither a lawyer nor a "hacker", but reading through the whole page you linked I can't figure out what part implies cars are covered? If they were, then it seems like it would put mechanics at best in a gray area.

Is it? I know it is illegal to strip a game and upload it to the internet. But is it illegal to save your own digital copy? I was under the impression that this violates terms of use, but isn't illegal. That the legality was focused around distribution.

IIRC Sony lost that court case where the Navy turned their Playstations into a supercomputer.

I'm not trying to argue, but I'm trying to state my understanding so someone can better help me understand. I really do want to know how many crimes I've committed lol
