Despite the provocative headline, it's not a bad rule of thumb.

But at least in the US, pretty much any new EV you can buy has a rated range of 200 miles or more. More than 100 miles of commuting per day is a lot! Also, workplace charging is becoming more of a thing, and would effectively double your range without any additional inconvenience.

Ironically, the inefficiency of ICEV engines is what makes them less variable in their range. First, you get heating for free because the engine produces an abundance of excess heat. Second, since the engines are at best 30% efficient, the effect of things like drag and grade are far less noticeable in terms of fuel consumption.
