Irrelevant. The point is that if your destination is less than 250 miles away, then it doesn't matter whether the car charges in 5 minutes or 50.

It's not irrelevant, as the whole point of this particular thread was the hypothesis that many people want to travel further than 250 miles.

"Many" does not mean most. Cars which need to drive more than 250 miles at a time are a niche market. The only reason there is a desire for that amount of range is because of the incredible inconvenience involved in stopping at a gas station multiple times per week.
