This is what the car is smart enough to do but appears not to be doing under one extreme circumstance which should help all of us in the long run. It does transition between regenerative and friction brakes all by itself. Possibly the software change will be to add a variable of when it switches to friction (temperature limit or something?). Something caused them to crash (computer speaking) not sure if it was temp. It stranded 6 of them but did not hurt anybody/thing from what I understand.Maybe my wording was bad, but in this case you would use the conventional brakes, which means it turns to heat. The brake disks are huge heat sinks.
I would switch half way down such a steep descent until patched. Plenty of old cars have brake-failures in that particular hill due to stress on the discs.
Even in any ICE car with only friction brakes I would still want really really good brakes going down that mountain where it happened. I can see the braking system getting pretty warm going down that. I would also bet there are a few old local stories about that descent. Wonder how they do on rotors around there (replacing warped ones that is). You can make the rotors glow red under the right circumstances. Huge heat sink is a relative term.
Are you referring the the MME's in Norway or in general? If in general I am providing my case of permanently broke.Nothing is permanently broken.
