To ensure that the update process finishes without interruption due to weak battery - if that happens it can brick your car. Tbf you can also just connect the battery to a power source and keep the engine off. Depending on update and car updates that take a few hours are not unheard of
That’s a really nice thought and I agree, but it doesn’t answer any of the practical questions the current of many countries often poses. Imo a, maybe temporary, solution that protects these artifacts is necessary.
Sadly FP will not change for these kinds of reasons, which is not saying we shouldn’t push for it nevertheless. In the meantime I fear not much good will come from an idealistic stance but rather practical solutions that at least preserve the hope we can at some point in time marvel at artifacts in their proper context. Just my opinion though
