I did a full discharge/charge test a month ago. After dividing the two numbers (original vs current) the battery still has 99.4% of its original capacity. This is after about 2500 charges, although many of those are just quick 10 minute top offs. At this rate these batteries could probably go a half million miles or more before there is any noticeable loss in range, and even then they will still work fine for most uses. I think real soon people will realize battery life isn't an issue anymore.
If the batteries will last longer than a motor or transmission in a gas car before they blow up and need to be replaced it's actually a reason to buy an electric vehicle. In fact there's a good argument never to buy a gas car, as you know after 100,000 miles the transmission will fail and 150,000 the motor will need to be replaced. Electric vehicles don't have these problems.
We are so used to cars breaking down and service stations all over the place we forget how awful and problematic gas vehicles really are until you ride electric for a while and realize you'd never go back to gas ever again, and wonder why everyone else on the road puts up with a gas vehicle and doesn't get an EV. They just must not be informed yet is all I can think.
