The fact that your car can drive 700 miles without a fill-up does not mean
that you can drive it that far without a break.

For me, a practical use case is to be able to drive 1-2 hours between
breaks. I have a petrol car, but if I had an electric car, I'd just plug
it in at each rest break.

Would you normally take a rest break for as long as it *really* takes to
recharge a car - not the fairyland figure of 5 minutes.
