Its really hard for product designers to get how problematic temperatures are in Canada and the upper plain states. It comes up a lot when dealing with poor people and vehicles. You need to keep it running in -20F / -29C to 100F / 38C. Heck, I remember one winter (89?) where the temp went from 60F to -20F in one day. That was problematic.
