A lot of ICE cars won't even start at 40 below. Those cases should count as zero mile range
To be fair, it typically costs about $50 for a block heater which allows you to start below 40 degrees in an ICE. Whats the solution for EV?
Even if not plugged-in they'll try to keep the battery above temperatures that may be damaging, e.g. -30C. This only works for a sufficiently charged battery.
