One problem for holidaymakers renting electric cars is that the charging infrastructure in rural areas isn't as thorough as it is on the UK's motorways.
Airbnb owner claims holiday makers running cables out the window is theft if electricity.
Just to pay devil's advocate for a moment - but let's imagine the house has oil heating (heating oil is basically diesel). Ignoring the problems of unpaid duty, given that the heating oil is provided as part of the holiday home's services, would it be theft if a guest filled up their diesel car from the heating oil tank? If that would be theft, why would (at least in the holiday home owner's opinion) it be unreasonable to not treat charging an electric car off the house supply in the same way, as clearly just as the heating oil isn't intended to be put in guests cars, the electricity isn't, either?
That's not the same, because fuel stations exist. You're expected to refuel at a fuel station, which can also be done nearly instantly. You do not leave your car.
An electric car is expected to be charged at home. You can charge them at work, or during a pit stop, but you CANNOT leave them at public charging places, and public charging varies a ton depending on location.
If there was a close by public charge station with overnight charging, sure, but there's not, and it's unreasonable for someone to expect a visitor to come and not recharge their car.
Are they supposed to wake up in the morning, drive to a public charger, and then sit there for 2 hours in the morning? No. No one does that. They drive home and charge over night if they're able to make it home.
I used to live in a house which used real diesel for heating. It was in a different country though. But the thing was that we had a special diesel storage. Meaning that the amount of fuel was limited. If I'd rent you such a house, I would put only as much fuel as you need to keep you warm during your stay. If you refuel your car with it, then you'll freeze to death at -30°. Your choice, mate, lol.
