So what would you call a reasonable range, then, bearing in mind the
need to have some reserve because of that detour, or the extra part of
the trip cos you just remembered you need a widget from B&Q?

Or the temperature has just fallen to -0C and the "fully charged"
battery is only good for half the distance because you are using 1KW/h
just to keep warm inside the car.
