Well?
A gasoline engined car makes as much power with one gallon in the tank as it does when it's full. It's takes less than 5 minutes to fill the tank back up once empty and still there is no power loss.
When you pull your electric car draggin' ass into the garage near empty and then your kid suddenly falls off his bike and breaks his arm are you gonna tell him he needs to wait 8 hours before you take him to the emergency room?
And once that battery is toast, who's landfill are you gonna put it in?
