I don't think they have to do with inefficiency. Predictability is there because combustion engines operate the same regardless of weather conditions. AC / energy consumption anxiety doesn't exist because of said predictability as well as your ability to refill 1000km worth of fuel in a couple minutes. The only difference if ICE were 100% efficient would be a slightly smaller gas tank.
