I too have a Leaf. It is perfect for my 60km round trip commute from Rangiora to Christchurch. In summer it will also get me from home to Waikuku Beach and back so I can go for a swim/play in the evening. That's charging it to 80% overnight.
Currently I even have it set to pre-heat in the morning, so the car and steering wheel are warm and the the windscreen de-iced.
It might be fugly, but it's great to drive and very cheap to run.
The i3 is great for really tall people - huge range of adjustment in the steering wheel and seat - just think of it as an odd two seater with loads of luggage space
The i8 is more supercar than commuter car and merely a hybrid, but driven properly sure as hell doesn't sound like an EV!!. It's also almost impossible to get out of - it has scissor doors which lower when you pull down on them for leverage. Even my teenage son found it difficult!
As for disposal, the batteries have a long life in the cars, and even after that can be re-purposed for static power storage, e.g. solar systems.
So it's EV during the week, but diesel Triton for weekend fun
