Not everyone in New Zealand lives in cities. Out here, fibre is something off a sheep's back and an EV charger would be as much use as a chocolate fireguard.
Fortunately both EV ranges and capabilities are rapidly improving. But speaking as someone who needs his sheep sheared at the moment and also drives an EV every day, I'd really like to get fibre at some point in the next 50 years.
Range is not the issue as much as load capacity, towing capacity, off road ability etc etc.
Imagine an EV that will carry 4 blokes, 6 dogs, towing a trailer loaded with 3 tonnes, across farm terrain, in temperatures of -5. All Day. And charges in 10 minutes.
Then you'll be there.
