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.


I've done 900 miles with just a driver switch and 1200 miles with a 45
minute break half way

Plus cross channel ferry of course

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.


nah. I tend to do 4 hours a stint

I regularly do 6 hours non stop and 14 hours less often.
