All you have quoted is your perceptions and predictions, not hard evidence. But your perception of 80% battery life after 6 years is garbage backed up by the fact that no manufacturer will guarantee batteries over 8 years old. No doubt they will get better with time but the early generation EVs will be worth little when you have to pay £4k for a new battery for a Nissan( your figures). Like I said before EV needs to mature and the comments about chargers, queues and lack of infrastructure back this up even on this thread.
Why would an EV worth little when it can still do 50% of its original range? Similar to current crop of limited range EV's, it's still a car, it is still far cheaper to run than a petrol supermini. It will still work great as a second car for school runs. Not everyone need to drive to Scotland in a moment's notice, sub-200 miles EV doesn't work well for long distance driving before warranty runs out, it will not work well with a new battery.
No 18k service intervals aren't standard.
Unless your car is outside the manufacturer warranty period, your car will still need to be serviced by a vat registered garage at the required intervals or you will be in breach of warranty and the manufacturer will be less likely to honour any claims. There is a great deal more to a service than brake fluid and pollen filter change.
Like visual inspections and other checks? There's really nothing needs
doing for minor servicing of the Leaf, and only 2 real work being done for major servicing.
On ICE, there's the engine oil, oil filter, air filter on top of the same checks.
Then there's also extra items that will cost more than a new Leaf battery people forget often: DMF, DPF, EGR, new clutch and rusted exhaust.
If an ICE car has an issue out of warranty an awful lot of the parts can be replaced at a fraction of the cost of an EV battery. Not sure any single component on an ICE cost that much, no doubt somebody in the motor trade can confirm that. Therefore more viable to keep going.
If an out of warranty EV has a problem with battery degradation, you can swap out individual cells cheaper than a new car 12v battery. Only difference is there isn't a lot of garages have the expertise at the moment, but it will change as more and more EV's on the road age.
Replacing the battery is akin to replace the whole ICE.
Im not writing it off at all, i'm saying EV technology is not yet ready to take over from ICE. Modern petrol engines are cleaner and more fuel efficient than they have ever been and certainly much more user friendly than any EV. EVs are great for short city commuting where there is the infrastructure and demand for what is a pretty narrow mode of transport with very poor range.The early generation EVs will be worth nothing when their batteries die - hardly a green solution! EVs will get there but not yet and certainly not outside the major conurbations..
I totally agree on EV as a solution to personal transport and it's not ready to go beyond home charge point yet.
But I don't agree on user friendliness of modern ICE cars, it may operate similarly, but under the hood there's too much going on these days. I press the accelerator and it doesn't go, it has to kick-down. I can't get traction in snow because of the non-smooth clutch work in the DSG. I drive normally and my MPG takes a nosedive when DPF is regeneration. I creep forward in traffic but stop/start interferes.
ICE may become cleaner and cleaner, but the clean vehicles doesn't get trickled down to the masses. Any slight improvement in the national grid is propagated to all EV's, no matter its age.
EV battery will not die like a ICE car won't start. This is just completely wrong on so many levels. The battery will degrade over time, giving you plenty of time (years!) to consider whether the car is still suitable for your needs.
