Drivers are generally irresponsible though, at least half the time. If an EV is running the heater, it will be lucky to last a few hours close to an idle traffic speed. Most won't wind up setting out with a perfectly full/charged battery either. An ICE vehicle can run the engine intermittently as such and benefit from the 'thermal inefficiency' to keep consumption under .2gallons/hour easily while remaining relatively comfortable/safe.
This is a very valid concern for owners and disaster management/planning staff alike.
How many people run their heater when evacuating a hurricane? Virtually no one because they don't hit when it is cold out.
They use 3-7 miles of range when running their A/C vs an ICE that will use 1-2 gallons of gasoline to do the same.
