I thought this until I looked at the histogram of private car trip lengths. The vast majority of trips are very short. Its unlikely they're all being done on the same day.
Yes, that is not an average situation, but there's a lot of peace of mind not having to think about it at all. By the time I get down to 250 miles in my ICE, I can fill up in 5 minutes, but still have a very comfortable margin for anything that may happen.
And, worst case, if I run out of gas (never happened in my lifetime)? I can get a gallon of fuel and drive away. How does that work with an EV?
