What if you show up at a gas
What if you show up at a gas station with 30 cars lined up? You can always come up with hypothetical situations that don't reflect reality. I've never been to a supercharger station with 56 chargers that was even 10% full, but if it was, with the average person using under 25 minutes, one would open up in 30 second.
My 2014 didn't have 400 miles of range, but it lost 6 miles of range since new with typical use. Don't act as if batteries won't last the life of the car. What if you buy a car and end up needing a new engine?
