You're assuming that you always start from a full charge (an assumption I used to make before I got an EV). That's not always the case. I live in a townhouse, so I'm in the process of getting a charging station installed (it's been six months so far and we're still in the paperwork stage ...) In the meantime, I charge where I can. That means I almost never start my day with a full charge. Worse, there are only a few places I can charge, and my best options add 20 miles of range in an hour. Say I start my day with 70 miles of range, which should be more than adequate for my ~45 miles of round trip commute. But an emergency comes up and I have to run an errand. It's just a short 10-mile trip, but now I'm coasting in to home with just 5 miles of range left ... if my meter is accurate (it's not), if traffic's not bad (it might be), etc. Charging stations are few and far between, which means the nearest one might be outside of my remaining range. Or, if I can get to one, it might be occupied. At a gas station I can just wait five minutes. At a charging station, I might have to wait hours for someone who's trying to get a full charge.
