Agreed to all points in the previous post. I have definitely observed the range differences in my ICE vehicles. The range of what I typically drive on long trips can vary from just over 300 miles (480 km) under adverse conditions (high speed, headwind and rain) to over 450 miles (720km) under optimum conditions (speed just above the transition from the friction dominated regime to the drag dominated regime with a tailwind).
What is different between ICE and EV is the range margin to other limits like time between comfort breaks etc.
The best EV have little or no range margin to a wide variety of users in long range driving. (Agree that EV have lots of range margin for the daily short range drives that constitute most trips.)
The majority of ICE have significant range margin.
There can be a lot of discussion as to what that long range definition is, and to how much range margin is required. Most would agree that the desired range is somewhere in the 200 to 350 mile (300 to 600 km) ballpark. Many EV have negative margin to these distances. The best electric car (a Tesla which claims 335 mi range) has somewhere between a small negative margin to 70% margin to the desired range, depending on your definition. There are a very few ICE vehicles that do not have range margin to the shortest range figure, while some have 100% margin to the long end of the desirable range. If you are operating with only a few percent margin you have to worry about wind and air conditioning. ICE vehicles are less likely to be operating in that few percent margin case, no matter how you define range requirements.
For me the desired long range segment is about 325 miles (520 km). So under very adverse conditions I end up with very little or even negative range margin in the ICE vehicle mentioned above. Which is why I have my gas gauge well calibrated and know all of the many options for refueling on that route segment. I can tell from the gas gauge if driving conditions have negatively affected range, and can select an earlier stop if necessary.
