What happens if he needs the heater and the wipers etc as well though?

On my EV there is no heater and the wipers and lights etc run from an
independent auxiliary battery so wouldn't affect the range as such,
especially in the dry and daytime. ;-)

So on a long journey in the rain the wipers and lights would pack up?
What's the capacity of the aux battery? Normal wipers draw between 5 and
10A at 12V so you'd need a big ass battery to keep then working all day
long.

It's charged from the traction battery.
It's a tiny battery. (No starter motor)
If it goes flat, the car can't be charged, run or anything.
