ICEs use much more fuel than usual for their first 10 minutes or so after a cold start, and they are subject to the same sources of increased drag like denser air, more viscous bearing and gear lubricants and increased rolling resistance on snowy roads. However, they also have the ability to capture a portion of the heat they normally waste to keep the windows clear and the occupants comfortable, while EVs need to use extra battery power for that. The maximum battery charge capacity and maximum charge rate also drop in the cold, so a fully charged EV is starting with less stored energy when it needs more to do the same job, and its ability to preserve energy using regenerative braking is compromised. Together, these things result in cold having a much larger effect on EV range than ICE range. Finally, the EV's lower normal range and slower refuelling rate adds to the inconvenience. When an ICE vehicle's range drops from 500 km to 350 km, the owner needs to spend 5 minutes and $50 at a gas station a couple of extra times a month. When an EV that used to be able to go 150 km can only go 80 km, an owner who needs to drive 100 km needs to spend an extra half hour hooked up to a charger every day. It likely still costs less than feeding gasoline to an ICE, but it is much more of a PITA.
I agree with much of your post although I think you give something of a pass to ICE vehicles. There is no waste heat until the ICE has reached operating temperature. Or put another way, ICE efficiency is quite a bit worse when cold. My Prius was a champion when it came to time to heat up the ICE but I think it mostly reflected the fact that the car had a small Alu block and the car prioritized ICE warm-up. Owners who did not wish to wait used resistance heating or came to Prius forums complaining that their hybrids were no better than a regular ICE in the cold weather. Somewhat ironically they were told the same thing as I am telling EV owners here: short trips take a hit to fuel economy.
This requirement to warm up the engine block after every cold soak plays out all the time with ICE owners but they usually do not understand what is going on. They have just gotten in the habit to run the ICE to "pre-heat" the car for 10-30 minutes before they drive the car. You can bet that these ICE cars put through the same protocol that the AAA used would show awful fuel economy.
Do ICE owners then say "Ahh, I guess that means I cannot take my ICE out for a long trip ?"
Obviously no, for two reasons:
1. is that they refuel more often
2. The other is that during a long trip the warm-up penalty is diluted by the length of the trip.
It is (2) where the AAA has failed so miserably.
Lastly, it is exactly because EVs pull all the energy from the battery that any EV worth its salt has heated seats and sometimes a heated steering wheel. The cars are engineered for efficient personal comfort although it is still possible to defeat the efficiency by stupidity. I cannot speak to AB type climates but I drive in 15F - 40F temperatures for most of the winter and I average ~ 250 Wh/mile overall by mostly relying on the seat heating for comfort and use of forced air as a supplement. And that was the second miserable fail of the AAA study: they did not use the EV as designed.
