In practice we're seeing ~25% loss of capacity at 40k miles in LEAF real world testing. 30% loss at 50k miles is the accepted norm. Capacity goes down annually after that. It seems that some cars are doing better, but play cars owned by the rich that get very few miles like the early Tesla sportscars. Real world daily-drivers like the LEAF experience the exact decay that was predicted. Lithium-ion isnt some new hot tech we don't understand. We understand it very well.

Americans replace their car every 6 years now. You may have 30-50% capacity at year 6, depending on a lot of factors. This is unacceptable considering the anemic range of a new battery. EV means losing almost all your car's value after 3-5 years. High trade-in values we enjoy now will be lost as the majority of the cost of the vehicle will be its battery. These batteries will fill landfills and be an environmental disaster.
The current "fix" is just to build the battery replacement cost into the warranty. So now your car is more expensive. Warranty claims now become a legal struggle over what is faulty or not. Nissan claims 70% battery power is non-faulty. That means your 75m LEAF range is now ~50m. My gas car gets that in a gallon and a half.
>You also seem to be VERY anti-tesla as seen in your other posts in this thread.
Its a 12 year old company that has done nothing but burn money. They have no mature product on the horizon and their promises of making a middle-class cheap EV with great range and durability are just not in the realm of technology. The stock has been on a decline since mid last year and they have a celebrity CEO who is good at PR and gimmicks but not delivering affordable vehicles.
>Also, saying the only incentive of buying an electric car to save money
This is the only motivator for mass market acceptance. The idle rich love the acceleration of that $100k car, but that doesn't matter to someone who makes half or a third that in a year.
