You can replace the fuse (not that easly) but for approximately the same price in a BMW. You do have to put in more work but the problem is with re-certifying the battery. Tesla does not care if the battery was damaged in the crash, they will (more or less) happily re-enable it. BMW decided that the only safe way is to re-certify the whole battery. I'm not saying it's the right decision, I think they over did it and VW does it better - but I do understand WHY they chose to do it so, and the WHY is not nearly as outrageous as a lot of people here think.

Ah that's interesting, IIRC in the video I'm thinking of they did get a 3rd party engineer to come out with a laptop and re-enable the battery in Tesla Toolbox, so that fits with what you're saying.
