So exactly what was the route of the ‘service’ shuttle... Did it ever go through winter conditions... When it snows, and blows, etc? It would be lovely if we all had weather like California.... But most of North America suffers from this condition that starts in December and doesn’t end until April and it’s called winter. And if you live north of the border, it starts in November and sometime it doesn’t end until May... Let’s see what the maintenance cost is for a Tesla shuttle in Minnesota, or Calgary.
A good question.
No snow, no salt, seldom use the heater, but lots of AC.
Note the AC croaked at 290 K.
