ICEs are significantly less efficient at startup and until they get up to their normal operating temperatures. That's not so much a problem for long range trips

ICEs are significantly less efficient at startup and until they get up to their normal operating temperatures. That's not so much a problem for long range trips, but taking multiple single-digit mile trips spaced apart in the time dimension.
Overblown, at least for modern cars. Girlfriend sometimes drives an ICE 1.5 miles to work, Gas mileage suffers ~30% versus freeway driving. When I did ~7 mile trips to work and back efficiency was <20% worse than freeway driving. Combustion chamber temps warm relatively quickly.
EVs have no problem "starting" in low temperatures. You might not be able to draw as much power for the drive train as the pack is heating up, but it's not a primordial "fuel-air-mix won't explode" problem.
In theory you're correct. In practice, ICEs will start and operate at temperature of -40F (perhaps with a bit of help heating the oil). The Tesla in the article was brought to its knees in temperatures within the positive teens.
And then this is mostly an issue of infrastructure; if there were at least 120V plugs at every parking lot, you wouldn't ever have to worry about these vampire loads.
Except now you have to convince everyone to install 120V plugs in parking lots, wire them up, figure out a way to bill for this or provided it for free, AND you have to remind the consumer to plug in every time they park their car.
