I think you have a pretty big misunderstanding if you think that electric cars are driven like petrol cars where you always charge to 100% and then don't charge until the battery is at 0%.
Your link has a graph[1] that indicates that while using 75%-25% charging states, which is what most of the electric cars use by default, you would get 10 000 cycles and still retain 80% of the original capacity. On a 500km range electric car, like that hypothetical Tesla Model 3, that would be 80% capacity left after 2 500 000km. You can Google quite easily that there are for example Tesla Model S cars with over a million kilometers driven.
