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.

Have you never driven longer journeys "non-stop", with just pauses to
visit the toilet and swap over drivers?

Manchester to Dover, across to Calais, along to just past St. Malo, a
visit to a house, a visit to a "solicitor" to buy it, to a hardware shop
for woodworm spray, to the house, back to Calais, across to Dover and
back to Manchester. Three of us, over a weekend, so as not to lose time
off work.

Also, "non-stop" Manchester to the south of France and Manchester to
Nottingham to Stuttgart.

And a number of others.
