I can understand that. I have an OBD-II module that I’ve used on my EV to unlock certain stupid locked features (including larger gas tank capacity — it’s a PHEV), but I definitely didn’t want to touch anything that could cause, say, a computer crash while driving down the road. But I’ve also had tires blow out, headlights fall out, transmissions break, and engines seize over the years as well. There are plenty of mechanical things that anyone could do that would cause catastrophe on the roads. I just don’t wanna go overboard on the government involvement since I think we should be able to actually repair/tinker with/jailbreak whatever we own, especially when it costs tens of thousands of dollars.
