Likewise, there are plenty of plug-in hybrid cars which ought to be great home emergency backup generators (ie. they have a 40+ kilowatt generator and 7+ kilowatt inverter), but very few have this functionality even if the hardware in most cases supports it and would simply require a firmware update.

I had good luck with telling claude to rewrite my laptop bios to enable various power modes which were theoretically possible but disabled by firmware, like powering a fullsize screen from the laptop battery over usbc.

Maybe I'll tell claude to rewrite the car firmware too...
