I am a problem, but on the other spectrum - OEMs ain't getting the repair €€€ because people like me repair stuff (but a different approach than Vanja).

Then, almost no manufacturer that sells in the EU knows how to do this (Renault is almost the only one that doesen't have pyrofuses in the battery, almost everyone else has). The catch is, the routed power is not problematic, the problem is when something gets squished and redirects that routed power to somewhere else. Which tends to happen in a metal tincan.
