I can pull my 12V out and bring it inside to warm up though
I think you missed the point. EVs also have a 12v, for the same basic reason of starting the vehicle. But the bigger factor is that EVs are often plugged in, which will automatically warm the battery.
I was under the impression that the 12v also runs all the standard car electronics
That is correct, and EV's are equally dependant on the 12V battery as ICE vehicles
It does, but that's because the 12v starter battery was already present. The electric starter predates any electronics. This just made an easy and available source of power for anything else that came later.
There's actually a movement to switch to a higher voltage, such as 48v, but there is a ton of inertia to overcome with that.
